2 System management
####### This section describes the tools and utilities that provide system management for the workstation.
Topics Power management features on page 23 BIOS ROM on page 24 Computer Setup (F10) Utility on page 25 Desktop management on page 32
Power management features
ERP compliance mode This computer provides ERP compliance mode capability. When this feature is enabled, the computer shuts down to the lowest possible power state. The computer must then be turned on with the power button. One of the effects is that "wake on LAN" is disabled. When this feature is disabled, the computer shuts down conventionally.
Enabling ERP compliance mode
Disabling ERP compliance mode
Power management features 23
#### Hyper-Threading Technology (HTT)
This computer supports HTT, an Intel-proprietary technology that improves processor performance through parallelization of computations (doing multiple tasks at once).
The operating system treats an HTT-enabled processor as two virtual processors and shares the workload between them when possible. This feature requires that the operating system support multiple processors and be specifically optimized for HTT.
Use the Computer Setup (F10) Utility to enable HTT. Go to http://www.hp.com/go/quickspecs to determine if your processor supports HTT.
#### SATA Power Management
SATA Power Management enables or disables SATA bus and/or device power management.
#### Intel Turbo Boost Technology
The HP Z Workstation series supports Intel® Turbo Boost Technology.
This feature enables the processor to run at frequencies above the normal frequency. When all processor cores are not necessary for the workload, inactive cores are turned off and power is diverted to the active cores to increase their performance.
Turbo Boost is enabled and disabled with the Computer Setup (F10) Utility. Go to http://www.hp.com/go/quickspecs to determine if your processor supports Turbo Boost.
BIOS ROM
The BIOS ROM is a collection of machine language applications stored as firmware in ROM. It includes functions such as Power-On Self-Test (POST), PCI device initialization, Plug and Play support, power management, and Computer Setup (F10) Utility.
Go to http://www.hp.com/go/quickspecs to review the latest BIOS ROM specifications.
Computer Setup (F10) Utility
######## Topics
Computer Setup (F10) Utility functions on page 25 Accessing Computer Setup (F10) Utility on page 26 Computer Setup (F10) Utility menu on page 27
#### Computer Setup (F10) Utility functions
This section presents the Computer Setup (F10) Utility functions. In most cases, OS-specific information is described for a Windows-based computer, however much of this information applies to all operating systems. Occasional notes about non-Windows operating systems are included.
Computer Setup (F10) Utility enables you to perform the following tasks:
#### Accessing Computer Setup (F10) Utility
Accessing Computer Setup (F10) Utility requires a keyboard. To access Computer Setup (F10) Utility:
If you do not press F10 or Esc at the appropriate time, try again. Turn the workstation off, then on, and press F10 again to access the utility. You can also press Ctrl+Alt+Del before starting if you do not press F10 before the message disappears.
In the Computer Setup (F10) Utility menu, the following headings are displayed: Main, Security, Advanced, and UEFI Drivers.
NOTE: The option for selecting the language is available on first boot only. To reset the selection, press Esc during POST and from the Startup menu, select Change Language to switch between languages.
| | |---|
CAUTION: Do not turn off the workstation while saving Computer Setup (F10) Utility changes, because the Complementary Metal-Oxide Semiconductor (CMOS) nonvolatile storage could become corrupted. Turn off after you exit the F10 Setup screen.
Computer Setup (F10) Utility menu The following table describes the functions available in the Computer Setup (F10) Utility menu. NOTE: With new BIOS releases, the following content is subject to change, so the menu might be different than shown.
| | |---|
Heading Option Description Main System Information Displays the following information:
Update System BIOS Enables you to upgrade the BIOS from a ROM image on a CD, USB flash drive, or hard drive or network.
Set Machine Unique Data
Provides these options:
Replicated Setup Provides these options:
Save Custom Defaults Saves the current settings as default settings for the next operation. Apply Factory Defaults and Exit
Restores the factory settings as the default settings for the next operation.
Apply Custom Defaults and Exit
Restores the default settings defined in Default Setup.
Ignore Changes and Exit
Exits workstation setup without applying or saving changes.
Save Changes and Exit Saves changes to system configuration and exits the workstation setup.
Security Set up BIOS Administrator Password
Enables you to set and enable a setup password for the administrator. If you create a setup password, you must use it to change workstation setup options, to flash the ROM, and to make changes to certain Plug and Play settings under Windows.
Set up BIOS Power-On Password
Enables you to set and enable the power-on password.
Change BIOS Power-On Password
Allows you to change an existing BIOS Power-On Password.
DriveLock Security Lets you assign or modify a master password or user password for hard drives. When enabled, this feature prompts the user to provide one of the DriveLock passwords during POST. If the user does not successfully enter one of the passwords, the hard drive remains inaccessible until one of the passwords is successfully entered during a subsequent cold-boot sequence.
NOTE: This selection appears only when the system includes at least one drive that supports the DriveLock feature.
Password Policy Allows you to control the characteristics of a valid password. TPM Embedded Security
Allows you to control TPM once a BIOS Administrator password is set.
NOTE: Embedded Security Device must be set to Device Available in the Device Security menu, and you must create a Setup Password, in order to configure the Embedded Security Device.
Embedded Security Device—(Hidden or Available) turns the Trusted Platform Mechanism (TPM) on and off. Device Hidden is the default. If this option is made available, the following options become available:
— Reset to factory settings
— Measure boot variables/devices to PCR1 For more information on TPM go to http://technet.microsoft.com/en-us/library/ cc749022(v=ws.10).aspx.
To enable the Embedded Security Device and to access any security features associated with the device, you must enter a setup password.
Setting a device to Available enables the operating system to access the device. Hidden makes the device unavailable. It is disabled by the BIOS and cannot be enabled by the operating system.
CAUTION: Choosing Reset to Factory Settings may result in significant data loss. The embedded security device is a critical component of many security schemes. Erasing the security keys prevents access to data protected by the Embedded Security Device.
USB Device Control Set workstation USB ports to Enabled/Disabled:
Slot Settings Lets you enable or disable any PCIe slot. System Security Provides these options:
— Reset of Embedded Security Device through OS—Enables or disables the ability of the operating system to reset the TPM. Available only when OS Management of Embedded Security Device is enabled.
— No PPI provisioning
— Allow PPI policy to be changed by OS Advanced Boot Options Enables you to configure the boot order by physically reordering the menu entries. The following is the default boot order presented in the menu:
— OS-specific Boot Manager

For more information, go to http://www8.hp.com/us/en/ads/clientmanagement/drivers-pack.html.
#### HP SoftPaq Download Manager
HP SoftPaq Download Manager is a free, easy-to-use interface for locating and downloading software updates for the HP client PC models in your environment. By specifying your models, operating system, and language, you can quickly locate, sort, and select the SoftPaqs you need. For more information, go to http://www8.hp.com/us/en/ads/clientmanagement/drivers-bios.html#softpaq-download-mng.
#### HP System Software Manager
HP System Software Manager (SSM) is a utility that is available on Windows computers. It enables you to update system-level software on multiple systems simultaneously. When executed on a PC client system, SSM detects hardware and software versions and then updates the software from a central repository, known as a file store. Driver versions supported by SSM are noted with a special icon in the software, on the driver download website, and on the Support Software CD.
To download the utility or to obtain more information about SSM, go to http://www8.hp.com/us/en/ads/ clientmanagement/drivers-bios.html#system-sw-mng.
#### ROM Flash
BIOS settings are stored on a programmable flash ROM. By establishing a setup password in Computer Setup (F10) Utility, you can protect unauthorized users from modifying the BIOS settings. This function is important to be sure that the operating integrity of the computer.
To upgrade the BIOS, download the latest SoftPaq images from http://www.hp.com/support/ workstation_swdrivers.
##### Remote ROM Flash
Remote ROM Flash allows system administrators to safely upgrade the ROM on remote HP computers from a centralized network management console, resulting in a consistent deployment of, and greater control over, HP PC ROM images over the network.
To use Remote ROM Flash, the computer must be turned on, or turned on using Remote Wakeup. For more information about Remote ROM Flash and HPQFlash, see the HP Client Manager Software or System Software Manager sections at http://www.hp.com/go/ssm.
##### HPQFlash
The HPQFlash utility is used to locally update or restore the system ROM on PCs using a Windows operating system. For more information about HPQFlash, go to http://www.hp.com/go/ssm, and enter the name of the computer.
FailSafe Boot Block FailSafe Boot Block enables BIOS recovery in the unlikely event of a ROM flash failure. For example, if a power failure occurs during a ROM upgrade, Boot Block uses a flash-protected section of the ROM to verify a valid system ROM flash when power is restored to the computer.
If the system ROM is valid, the computer starts normally. If the system ROM fails the validation check, FailSafe Boot Block provides enough support to start the computer from a BIOS image CD that has been created from a SoftPaq. The BIOS image CD programs the system ROM with a valid image.
When Boot Block detects an invalid system ROM, the computer power LED blinks red eight times and the computer beeps eight times; then the computer pauses for two seconds. On some models, a Boot Block recovery mode message appears.
In preparation for system recovery, use the BIOS CD media file in the SoftPaq to create a BIOS image CD or USB flash drive.
##### Recovering the computer from Boot Block Recovery mode
To recover the computer after it enters Boot Block recovery mode:
If a setup password has been established, the Caps Lock light turns on and you are prompted for the password.
If the computer starts from the boot media and successfully reprograms the ROM, three keyboard lights turn on and a rising-tone series of beeps signals successful recovery.
#### Workstation security
This section provides information about providing system security through asset tracking, password security, hard drive locking, and chassis locks.
##### Asset tracking
Asset tracking features provide data that can be managed using HP Systems Insight Manager (HP SIM), HP Console Management Controller (CMC), or other systems-management applications.
Seamless, automatic integration between asset tracking features and these products enables you to choose the management tool that is best suited to the environment and to leverage investments in existing tools.
HP also offers several solutions for controlling access to valuable components and information:
The Smart Cover Sensor and cable lock are available as options on select systems. You can manage security settings as follows:
For more information about Computer Setup (F10) Utility, see Computer Setup (F10) Utility menu on page 27. The following Computer Setup (F10) Utility features let you manage computer security.
Feature Purpose Removable Media Boot Control Prevents booting from removable media drives USB Interface Control Prevents transfer of data through the integrated USB interface Power-On Password
Prevents use of the computer until the password is entered (applies to initial system startup and restarts)
Setup Password
Prevents reconfiguration of the computer (through Computer Setup (F10) Utility) until the password is entered
SATA hard drive security HP computers include the HP DriveLock facility for SATA hard drives to prevent unauthorized access to data. WARNING! Enabling DriveLock can render a SATA hard drive permanently inaccessible if the master password is lost or forgotten. No method exists to recover the password or access the data. DriveLock has been implemented as an extension to Computer Setup (F10) Utility functions. It is only available when hard drives that support the ATA security command set are detected. On HP computers, it is not available when the SATA emulation mode is RAID. DriveLock is for HP customers for whom data security is the paramount concern. For such customers, the cost of a hard drive and the loss of the data stored on it is inconsequential when compared to the damage that could result from unauthorized access to its contents. To balance this level of security with the need to address the issue of a forgotten password, the HP implementation of DriveLock employs a two-password security scheme. One password is intended to be set and used by a system administrator, while the other is typically set and used by the user. No "back door" can be used to unlock the drive if both passwords are lost. Therefore, DriveLock is most safely used when the data contained on the hard drive is replicated on a corporate information system or is regularly backed up. If both DriveLock passwords are lost, the hard drive is inaccessible. For users who do not fit the previously defined customer profile, this outcome might not be acceptable. For users who fit this profile, the outcome might be a tolerable risk, given the nature of the data stored on the hard drive.
###### DriveLock applications
The most practical use of DriveLock is in a corporate environment. The system administrator would be responsible for configuring the hard drive, which involves setting the DriveLock master password and a temporary user password. If the system administrator forgets the user password or if the equipment is passed on to another employee, the master password can be used to reset the user password and restore access to the hard drive.
HP recommends that corporate system administrators who enable DriveLock also establish a corporate policy for setting and maintaining master passwords. This precaution will prevent loss of information if an employee sets both DriveLock passwords before leaving the company. In such a scenario, the hard drive is inaccessible and must be replaced. Likewise, by not setting a master password, system administrators might find themselves locked out of a hard drive and unable to perform routine checks for unauthorized software, other asset control functions, and support.
For users with less stringent security requirements, HP does not recommend enabling DriveLock. Users in this category include personal users, or users who do not maintain sensitive data on their hard drives as a common practice. For these users, the potential loss of a hard drive resulting from forgetting both passwords is much greater than the value of the data DriveLock protects.
Access to Computer Setup (F10) Utility and DriveLock can be restricted through the setup password. By specifying a setup password and not giving it to users, system administrators can restrict users from enabling DriveLock.
###### Using DriveLock
When hard drives that support the ATA security command set are detected, DriveLock appears under the Security menu in the Computer Setup (F10) Utility menu. You are presented with options to set the master password and to enable DriveLock. You must provide a user password to enable DriveLock. Because the initial configuration of DriveLock is typically performed by a system administrator, a master password should be set first.
HP encourages system administrators to set a master password whether they plan to enable DriveLock or not. This gives the administrator the ability to modify DriveLock settings if the drive is locked in the future. After the master password is set, the system administrator can enable DriveLock or leave it disabled.
If a locked hard drive is present, POST requires a password to unlock the device. If a power-on password is set and it matches the device’s user password, POST does not prompt the user to re-enter the password. Otherwise, the user is prompted to enter a DriveLock password.
For a cold start, use the master or user password. For a warm start, enter the same password used to unlock the drive during the preceding cold start.
Users have two attempts to enter a correct password. During cold start, if neither attempt succeeds, POST continues but the drive remains inaccessible. During a warm-start or restart from Windows, if neither attempt succeeds, POST halts and the user is instructed to cycle power.
###### Enabling DriveLock
To enable and set the DriveLock user password:
If you do not press F10 at the appropriate time, you must restart the computer, and then repeatedly press F10 to access the utility.
| | |---|
When the computer starts, you are prompted to enter the DriveLock password for each DriveLockcapable drive for which you have set a password. You have two attempts to enter the password correctly. If the password is not entered correctly, the computer attempts to start anyway. However, the boot process most likely fails because data from a locked drive cannot be accessed.
In a single-drive computer, when DriveLock is enabled, the computer might not be able to boot to the operating system, and might try to boot from the network or from another storage device (depending on the boot ordering options). Regardless of the outcome of the start attempts, the locked drive remains inaccessible without the DriveLock password.
In a two-drive computer that has a boot drive and a data drive, you can apply the DriveLock feature to the data drive only. In this case, the computer can always start, but the data drive is accessible only when the DriveLock password is entered.
Cold starts require that you enter DriveLock passwords. However, DriveLock passwords are also required for warm starts. For example, if you boot to DOS and press Ctrl+Alt+Del, you must enter the DriveLock password before the computer completes the next start cycle. This warm-start behavior is consistent with the DriveLock feature.
##### Password security
The power-on password prevents unauthorized access to applications or data when the computer is turned on or restarted. The setup password specifically prevents unauthorized access to the Computer Setup (F10) Utility and can also be used as an override to the power-on password. An administrator can enter the setup password at the prompt for the power-on password and gain access to the computer.
You can establish a network-wide setup password to enable the system administrator to log in to all network systems to perform maintenance without needing to know the power-on password.
###### Establishing a setup password using Computer Setup (F10) Utility
Establishing a setup password through the Computer Setup (F10) Utility prevents reconfiguration of the computer (through the use of Computer Setup (F10) Utility) until the password is entered.
To establish a setup password using the Computer Setup (F10) Utility menu:
If you do not press F10 at the appropriate time, you must restart the computer, and then repeatedly press F10 to access the utility.
###### Establishing a power-on password using computer setup
Establishing a power-on password through Computer Setup (F10) Utility prevents access to the computer when power is connected, unless you specify the password. When a power-on password is set, Computer Setup (F10) Utility presents Password Options in the Security menu. The password options include Network Server Mode and Password Prompt on Warm Boot.
When Network Server Mode is disabled, you must enter the password when the computer is turned on and the key icon appears on the monitor. When Password Prompt on Warm Boot is enabled, you must enter the password. The password must also be entered each time the computer is restarted. When Network Server Mode is enabled, the password prompt is not presented during POST.
To enable Network Server Mode, you must set a power-on password under Advanced > Password Options. This option enables the computer to start without requiring the power-on password, but the keyboard and mouse are locked until you enter the password.
To establish a power-on password through the Computer (F10) menu:
If you do not press F10 at the appropriate time, you must restart the computer, and then repeatedly press F10 to access the utility.
###### Entering a power-on password

###### Cable lock (optional)
To prevent theft, you can attach a keyed cable lock to the bottom-left corner of the chassis. This cable lock attaches to the chassis and secures it to the work area.
#### Fault notification and recovery
Fault notification and recovery features combine innovative hardware and software technology to prevent the loss of critical data and minimize unplanned downtime.
If the computer is connected to a network that is managed by HP CMS, the computer sends a fault notice to the network management application. With HP CMS, you can also remotely schedule diagnostics to run on managed PCs and create a summary report of failed tests.
##### ECC fault prediction
When the computer encounters an excessive number of error checking and correcting (ECC) memory errors, it displays a local alert message. This message contains information about the errant DIMM, enabling you to take action before you experience noncorrectable memory errors. ECC DIMMs are standard on this computer.
##### Thermal sensors
Several thermal sensors in the HP Workstation regulate computer fans to maintain an acceptable, efficient chassis temperature.
#### Dual-state power button
With ACPI enabled, the power button can function as an on/off switch or as a button. This feature does not completely turn off power, but instead causes the computer to enter a low-power standby state. This enables you to go to standby without closing applications, and to return to the same operational state without any data loss.
##### Changing the power button configuration (Windows only)
CAUTION: To reduce the risk of data loss, do not use the power button to turn off the computer unless the system is unresponsive.

#### Battery
The battery that comes with the computer provides power to the real-time clock and has a minimum lifetime of about three years. Observe the following warning and caution when replacing the battery.
WARNING! HP Z Series Workstations use lithium batteries. There is a risk of fire and chemical burn if the battery is handled improperly. Do not disassemble, crush, puncture, short external contacts, dispose of in water or fire, or expose battery to temperatures higher than 60°C (140°F).
CAUTION: Before removing the battery, back up the CMOS settings in case they are lost when the battery is removed. Use Computer Setup (F10) Utility to back up the settings.
| | |---|
NOTE: Do not dispose of batteries, battery packs, and accumulators with general household waste.
#### Cable management
Proper routing of the internal cables is critical to the operation of the workstation. Follow good cable management practices when removing and installing components.
When removing the power supply power cable from the connector on the system board, always follow these steps:
CAUTION: Always pull the connector — NEVER pull on the cable. Pulling on the cable could damage the cable and result in a failed power supply.
#### Processor and processor heatsink
CAUTION: Observe the following cautions when removing or replacing the heatsink.
— When removing the heatsink, loosen all screws a little at a time to ensure the processor remains level. Do not fully loosen one screw, and then move on to the next.
— After you remove the processor heatsink from the chassis, use alcohol and a soft cloth to clean the thermal compound residue from the processor and the heatsink, allowing the alcohol on the processor and processor heatsink to dry completely.
— If you are reusing the original heatsink, apply thermal compound to the center of the processor top surface.
— If you are using a new processor heatsink, do not apply thermal compound to the processor because the new heatsink already has thermal compound applied to the heatsink surface. Instead, remove the thermal compound protective liner from the bottom of the new heatsink.
— Do not overtighten the heatsink screws. Overtightening can strip the threads in the chassis.
— Do not fully tighten one screw and then move on to the next. Instead, tighten all screws a little at a time, ensuring that the processor remains level.
CAUTION: Observe the following cautions when removing or replacing the processor.
— If you are installing a second processor, it must be of the same type as the first processor.
— Internal components might be powered even when the computer is off. To prevent damage, disconnect the computer power cord before you remove or install a component.
— The processor socket contacts and pads are extremely fragile. Do not touch the processor socket contacts or the gold pads underneath the processor. Use extreme care and handle the processor only by the edges.
— The processor socket contacts are delicate and bend easily. To avoid bending the contacts, use extreme care when installing the processor in the socket.
— Installing a processor incorrectly can damage the system board. Contact an HP authorized reseller or service provider to install the processor. If you plan to install the processor yourself, view the entire remove and replace video before you begin.
— Failure to follow the computer preparation instructions can result in an improperly installed processor, causing extensive computer damage.
#### Expansion slots
This section identifies and describes computer expansion card slots, and presents card configuration information.
Go to http://www.hp.com/go/quickspecs to learn which graphics cards are supported in the workstation, how much memory each graphics card includes, and graphics card power requirements.
##### Card configuration restrictions for power supplies
CAUTION: To prevent damage, the overall power consumption of the computer (including I/O cards, processor, and memory) must not exceed the maximum rating of the computer power supply. For power supply information, see Power supply specifications on page 69.
##### Choosing an expansion card slot
Whenever possible, use the following tips to help you select the proper slot for an expansion card:
— Install a PCIe Gen1 x16 or a PCIe Gen1 x8 card in the PCIe Gen2 x16 slot.
— Install a PCIe Gen1 x4 card in the PCIe Gen1 x4 slot. — Install a PCIe Gen1 x1 card in the PCIe Gen1 x1 slot. — Install a PCI card in the PCI slot.
— Whenever possible, install a PCIe x1 card in an x1 slot.
— Electrically matches the number of PCIe card lanes (for example, x1 in an x1 slot).
— Has more lanes electrically.
— Has fewer lanes, but is closer to your needs. For example, place an x16 card in an x4 slot, and an x4 card in a an x1 slot.

6 Configuring password security and resetting CMOS
This chapter describes how to configure password security and to reset CMOS.
Preparing to configure passwords Computer Setup (F10) Utility enables you to create setup and power-on passwords. There are three possibilities for setting passwords:
After you create both passwords, you can use the setup password in place of the power-on password as an override to log into the computer (a useful feature for a network administrator).
| | |---|
NOTE: You can only clear the passwords with the password jumper. Clearing CMOS does not clear the passwords.
CAUTION: Before pressing the Clear CMOS button, back up your computer CMOS settings.
Pressing the Clear CMOS button resets CMOS values to factory defaults and erases customized information, including asset numbers and special settings.
To back up the CMOS settings, run Computer Setup (F10) Utility and select Save to Diskette from the Main// menu.
Preparing to configure passwords 99
Resetting the password jumper
Use the following procedure to disable the power-on or setup password features and clear the power-on and setup passwords.
WARNING! To reduce the risk of personal injury from electrical shock and hot surfaces, be sure to disconnect the power cord from the wall outlet and allow the internal system components to cool before touching.

A Linux technical notes
HP offers a variety of Linux solutions for HP workstation customers:
| | |---|
NOTE: After you set up the operating system, make sure that the latest BIOS, drivers, and software updates are installed.
CAUTION: Do not add optional hardware or third-party devices to the workstation until the operating system is successfully installed. Adding hardware might cause errors and prevent the operating system from installing correctly.
System RAM
HP supports different amounts of total RAM in various HP workstations, based on the number of hardware DIMM slots and the capabilities of the system. The total memory supported for each configuration is listed in the Hardware Support Matrix for HP Linux Workstations at http://www.hp.com/support/ linux_hardware_matrix.
Audio
All HP workstations come with built-in audio hardware. The audio hardware is supported by the Advanced Linux Sound Architecture (ALSA) drivers included with all modern Linux distributions.
The audio hardware provides basic playback and recording features. The ability to simultaneously play audio from multiple sources, such as applications and CDs, is provided in the ALSA driver that provides audio mixing. The performance of software audio mixing and playback is greatly improved in ALSA version 1.0.13 and later.
After the driver is installed, the optional NVIDIA and AMD graphics cards that are supported in HP workstations also provide audio functionality over HDMI. The signal can be passed through the DisplayPort connector to a monitor with audio capabilities. The vendor driver must be installed. Such a configuration might present two audio hardware choices. If you do not hear sound through the speakers, one possible
System RAM 103
reason is that the graphics card (default) is selected for audio output instead of the DisplayPort. Check the audio settings (for example, Sound in gnome-control-center).
In some systems, embedded Intel HD graphics may also present a similar HDMI audio device that can be used through the DisplayPort interface. No proprietary driver is needed for this device, just a sufficiently recent kernel.
Network cards
All HP workstations include one or two integrated network interface controllers. Some support optional NICs. Most Linux distributions have drivers for these interfaces.
Hyper-Threading Technology
The Z Series Workstations support Hyper-Threading Technology (HTT), an Intel technology that improves processor performance by enabling the processor to simultaneously perform multiple tasks. The operating system treats an HTT-enabled processor as two virtual processors and shares the workload between them when possible. This feature can be used only if the operating system support multiple processors and is specifically optimized for HTT.
To enable HTT:
| | |---|
NOTE: On most recent Linux distributions (including RHEL 6, SLED 11, and updates to those streams), the kernel automatically detects that HTT is enabled and works correctly.
NVIDIA Graphics Workstations
Some workstation configurations come with NVIDIA Quadro graphics hardware. HP recommends the use of NVIDIA drivers for best results on Linux systems.
HP provides recommended versions of the drivers with RPM-compatible installers for RHEL and SLED distributions. These are available from the HP Installer Kit for Linux and from workstation driver repositories on hp.com. When HP installers are used, their contents and documentation links are located in the /opt/hp/ nvidia folder.
When installing Linux on a workstation that contains an NVIDIA card, administrators should select a VESAcompatible driver to avoid the instability that is experienced with some open-source versions of the Nouveau and DRM drivers.
Open-source versions of Nouveau drivers and NVIDIA drivers cannot coexist in the same runtime environment because they use the same hardware resources. If administrators create their own Linux environments using NVIDIA drivers but choose not to use HP-packaged versions, HP recommends that they manually append the following boot loader parameters to properly suppress the Nouveau driver at runtime (grub example below):
kernel /vmlinuz ... rdblacklist=nouveau nouveau.modeset=0 This action is applied by HP installers but must be applied/restored under other circumstances.
104 Appendix A Linux technical notes
To customize display characteristics and resolutions when the computer is using an NVIDIA driver, execute the following command:
/usr/bin/nvidia-settings To create and manipulate the /etc/X11/xorg.conf file, execute: /usr/bin/nvidia-xconfig
AMD Graphics Workstations
Some workstation configurations include AMD graphics hardware. HP recommends use of AMD graphics drivers for best results on Linux systems.
HP also provides recommended versions of AMD graphics drivers with RPM-compatible installers for RHEL and SLED distributions. These are available from the HP Installer Kit for Linux and workstation driver support packages on hp.com.
The open source RADEON and RADEONHD drivers can conflict with the AMD graphics drivers by claiming the hardware early in the boot process. The AMD driver installation process usually blacklists conflicting drivers and turns off kernel mode-setting in the initial RAM image.
Administrator customization of the display characteristics and many other aspects of an AMD graphics driver environment is available through the following command, which starts the Catalyst Control Center:
/usr/bin/amdcccle
Some settings for AMD graphics, including reconfiguration of the /etc/X11/xorg.conf file, can be accomplished through the many options provided by the following command:
/usr/bin/aticonfig Information can be found in these directories after the driver is installed: /opt/hp/ati /usr/share/ati /usr/share/doc/fglrx
If the automatic init script attempts to rebuild the kernel module, the name of the log file is /var/log/fglrxbuild.log.

Configuring Intel SATA RAID
This section describes how to use Intel® Rapid Storage Technology enterprise (Intel® RSTe) to set up and manage SATA RAID volumes.
| | |---|
NOTE: These instructions apply to Windows-based systems. They also apply to Linux distributions that include the isci kernel driver support for the RSTe technology. This driver is included on recent releases of most upstream and enterprise distributions, and may be available for addition to some previous releases. If this driver is not available in the distribution, or is not applicable to the platform (e.g., the RST controller), the Software RAID solution is recommended.
You can create a SATA RAID array that contains up to the maximum number of internal SATA hard drives and eSATA drives (if you use an optional eSATA bulkhead cable) supported on your workstation.
Two or more hard drives must be attached to a controller (sSATA) for that controller's option ROM to run. If two or more drives are on each controller, a unique option ROM executes for each controller.
The Intel SATA AHCI option ROM configuration utilities run when you select RAID+AHCI for the SATA emulation mode.
#### Configuring system BIOS
To set up a RAID configuration, the emulation mode must be set to RAID+AHCI in Computer Setup (F10) Utility. This is the default setting. If the mode has been changed, follow these steps to reinstate it.

Software RAID solution
This section summarizes software RAID considerations that are specific to the Linux environment, and provides links to additional configuration resources.
#### Software RAID considerations
The Linux kernel software RAID driver (called md, for multiple device) offers integrated software RAID without the need for additional hardware disk controllers or kernel patches. Unlike most hardware RAID solutions, software RAID can be used with all types of disk technologies, including SATA, SAS, SCSI, and solid-state drives. This software solution requires only minimal setup of the disks themselves.
However, when compared to hardware-based RAID, software RAID has disadvantages in managing the disks, breaking up data as necessary, and managing parity data. The processor must assume some extra loading: disk-intensive workloads result in roughly double the processor overhead (for example, from 15% to 30%). For most applications, this overhead is easily handled by excess headroom in the processors. But for some applications where disk and processor performance are very well balanced and already near bottleneck levels, this additional processor overhead can become troublesome.
Hardware RAID offers advantages because of its large hardware cache and the capability for better scheduling of operations in parallel. However, software RAID offers more flexibility for disk and disk controller setup. Additionally, hardware RAID requires that a failed RAID controller must be replaced with an identical model to avoid data loss, whereas software RAID imposes no such requirements.
Some software RAID schemes offer data protection through mirroring (copying the data to multiple disks in case one disk fails) or parity data (checksums that allow error detection and limited rebuilding of data in case of a failure). For all software RAID solutions on HP workstations, redundancy can be restored only after the system is shut down so that the failed drive can be replaced. This replacement requires only a minimum amount of work.
#### Performance considerations
Disk I/O bandwidth is typically limited by the system bus speeds, the disk controller, and the disks themselves. The balance of these hardware limitations, as affected by the software configuration, determines the location of the any bottleneck is in the system.
Several RAID levels offer improved performance relative to stand-alone disk performance. If disk throughput is restricted because of a single disk controller, RAID can probably do little to improve performance until another controller is added. Conversely, if raw disk performance is the bottleneck, a tuned software RAID solution can dramatically improve the throughput. The slower disk performance is, relative to the rest of the system, the better RAID performance will scale, because the slowest piece of the performance pipeline is being directly addressed by moving to RAID.
#### Configuring software RAID
See the following sites for additional information about configuring software RAID on Red Hat Enterprise Linux (RHEL) or SUSE Linux Enterprise Desktop (SLED):

D Statement of Volatility
Z440 Workstation
HP confirms that Intel-based Z440 personal workstation contains DDR RAM volatile memory (memory amount depends on the customer configuration). In addition, the motherboard in the condition originally shipped without subsequent modification or the addition or installation of any applications, features, or functionality, contain the following nonvolatile memory: PCH Real Time Clock (RTC) battery backed-up configuration memory (256 Bytes), Super I/O battery backed-up configuration memory (16 Bytes), masked keyboard ROM (2K Bytes), DIMM Serial Presence Detect (SPD) configuration data (256 Bytes per module, 128 Bytes programmable), TPM module (2.35 kB), and Serial Flash IC for System BIOS (128M Bits).
The volatile memory is cleared by removing power from the system for greater than 30 seconds. The nonvolatile memory on the motherboard is restored by following the steps below:
The DIMM SPD EEPROM is not readily available to the user, however there appear to be tools publicly available to read and write this part. To eliminate the possibility that it could contain sensitive information, remove the DIMMs or use one of these tools.

Z840 Workstation
HP confirms that Intel-based Z840 personal workstation contains DDR RAM volatile memory (memory amount depends on the customer configuration). In addition, the motherboard in the condition originally shipped without subsequent modification or the addition or installation of any applications, features, or functionality, contain the following nonvolatile memory: PCH Real Time Clock (RTC) battery backed-up configuration memory (256 Bytes), Super I/O battery backed-up configuration memory (16 Bytes), SAS FLASH memory (32Mbits) and an EEPROM (64K Bits), masked keyboard ROM (2K Bytes), secondary LOM Flash (4 Mbits), DIMM Serial Presence Detect (SPD) configuration data (256 Bytes per module, 128 Bytes programmable), TPM module (2.35 kB), and Serial Flash IC for System BIOS (128M Bits).
The volatile memory is cleared by removing power from the system for greater than 30 seconds. The nonvolatile memory on the motherboard is restored by following the steps below:
The secondary LOM Flash is inaccessible to the user via any publicly available tools. There are programs used by HP in manufacturing and R&D that allow access, but these are not available outside of HP. The embedded LSI 2308 SAS controller flash ROM can be read, written, and erased via a firmware and BIOS utility SASFLASH.exe available in the latest soft pack release on the HP website. The embedded LSI 2308 SAS controller battery backed memory can be erased following the instructions stated above in step 8. The DIMM SPD EEPROM is not readily available to the user, however there appear to be tools publicly available to read and write this part. To eliminate the possibility that it could contain sensitive information, remove the DIMMs or use one of these tools.
