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 specically optimized for HTT.

Use the Computer Setup (F10) Utility to enable HTT.

Go to http://www.hp.com/go/quickspecs to determine if your CPU 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 CPU to run at frequencies above the normal frequency. When all CPU cores are not necessary for the workload, inactive cores are turned o 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 CPU supports Turbo Boost.

BIOS ROM

The BIOS ROM is a collection of machine language applications stored as rmware 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.

ROM Flash

BIOS settings are stored on a programmable ash 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 ensure 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.

HPBiosUpdRec

The HPBiosUpdRec utility is used to locally update or restore the system ROM on PCs using a Windows operating system. For more information about HPBiosUpdRec, 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 ash failure.

For example, if a power failure occurs during a ROM upgrade, Boot Block uses a ash-protected section of the ROM to verify a valid system ROM ash 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 le in the SoftPaq to create a BIOS image CD or USB ash drive.

Desktop management 25

Recovering the computer from Boot Block Recovery mode

To recover the computer after it enters Boot Block recovery mode:

1. Remove any media such as USB ash drives or discs in the optical drives.

2. Insert a BIOS image CD into the DVD drive. You can also use USB media such as an HP DriveKey.

3. Turn the computer o, and then turn it on.

If no BIOS image CD or USB media is found, you are prompted to insert one and restart the computer.

If a setup password has been established, the Caps Lock light turns on and you are prompted for the password.

4. Enter the setup 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.

5. Remove the boot media and turn o the computer.

6. Restart the computer.

Workstation security

The following Computer Setup (F10) Utility features let you manage computer security.

26 Chapter 2 System management

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

Setup Password

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.

Prevents use of the computer until the password is entered (applies to initial system startup and restarts)

Prevents reconguration of the computer (through Computer Setup (F10) Utility) until the password is entered

If both DriveLock passwords are lost, the hard drive is inaccessible. For users who do not t the previously dened customer prole, this outcome might not be acceptable. For users who t this prole, 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 conguring 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 nd 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.

Desktop management 27

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

conguration of DriveLock is typically performed by a system administrator, a master password should be set rst.

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:

1. Turn on or restart the computer.

2. As soon as the computer is turned on, repeatedly press the F10 key until Computer Setup (F10) Utility

starts.

If you do not press F10 at the appropriate time, you must restart the computer, and then repeatedly press F10 to access the utility.

3. Select Security > DriveLock Security.

4. For each DriveLock-capable drive, select the drive by pressing Enter.

5. Under Enable/Disable DriveLock options, select Enable, and then press Enter to enable DriveLock for

that drive.

NOTE: To set the DriveLock master password, select Master.

CAUTION: If you forget the DriveLock password, the drive is inaccessible.

6. Enter a new user password (1 to 32 characters long), and then press Enter to accept.

7. Enter the password again in the Enter New Password Again eld. If you forget this password, the drive

is permanently disabled.

8. Select Main > Save Changes and Exit. Press Enter to accept the changes. After you press Enter, the

computer performs a cold start before invoking the DriveLock function.

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.

28 Chapter 2 System management

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 specically 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 reconguration of the computer (through the use of Computer Setup (F10) Utility) until the password is entered.

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.

CAUTION: Before removing the battery, back up the CMOS settings in case they are lost when the battery is

removed. To back up the CMOS settings, select the Save to Removable Storage option in Computer Setup (F10) Utility.

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.

●

Handle cables with care to avoid damage.

●

Apply only the tension required to seat or unseat cables during insertion or removal from the connector.

●

When possible, handle cables by the connector or pull-strap.

●

Route cables in such a way that they cannot be caught or snagged by parts being removed or replaced.

●

Keep cables away from direct contact with major heat sources, such as the heat sink. (Some air ow guides have a cable guide that lets you route cables safely around the heat sink.)

●

Do not jam cables on top of expansion cards or SODIMMs. Circuit cards and SODIMMs are not designed to take excessive pressure.

Component replacement guidelines 39

●

Keep cables clear of movable or rotating parts (such as fans, power supply, and drive cage) to prevent them from being cut or crimped when the component is lowered into its normal position and during normal operation.

●

When folding a at ribbon cable, never fold to a sharp crease. Sharp creases may damage the wires.

●

In all cases, avoid bending or twisting the cables. Do not bend any cable sharply. A sharp bend can break the internal wires.

●

Never bend a SATA data cable tighter than a 30 mm (1.18 in) radius.

●

Never crease a SATA data cable.

●

Do not rely on components like the drive cage, power supply, or computer cover to push cables down into the chassis. Always position the cables to lay properly by themselves or in the cable guides and chassis areas designed for cable routing.

When removing the power supply power cable from the connector on the system board, always follow these steps:

1. Press down the top of the retaining latch attached to the cable end of the connector.

2. Grasp the cable end of the connector and pull it straight out.

CAUTION: Always pull on the connector — NEVER pull on the cable. Pulling on the cable could damage

the cable and result in a failed power supply.

CPU (processor) and CPU heat sink

CAUTION: Observe the following cautions when removing or replacing the heat sink:

— When removing the heat sink, loosen all screws a little at a time to be sure that the CPU remains level. Do not fully loosen one screw, and then move on to the next.

— Do not overtighten the heat sink screws. Overtightening can strip the threads in the chassis.

CAUTION: Observe the following cautions when removing or replacing the CPU.

— Internal components might be powered even when the computer is o. To prevent damage, disconnect the computer power cord before you remove or install a component.

— Do not touch the CPU socket contacts or the gold pads underneath the CPU. Use extreme care and handle the CPU only by the edges.

— The CPU socket contacts are delicate and bend easily. To avoid bending the contacts, use extreme care when installing the CPU in the socket.

— Installing a processor incorrectly can damage the system board. Contact an authorized 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.

Using HP PC Hardware Diagnostics (UEFI)

HP PC Hardware Diagnostics is a Unied Extensible Firmware Interface (UEFI) that allows you to run diagnostic tests to determine whether the computer hardware is functioning properly. The tool runs outside the operating system so that it can isolate hardware failures from issues that are caused by the operating system or other software components.

When HP PC Hardware Diagnostics (UEFI) detects a failure that requires hardware replacement, a 24-digit Failure ID is generated. This ID can then be provided to support to help determine how to correct the problem.

To start HP PC Hardware Diagnostics (UEFI), follow these steps:

1. Turn on or restart the computer, and quickly press esc

2. Press F2.

The BIOS searches three places for the diagnostic tools, in the following order:

POST error messages and diagnostic front panel LEDs and audible codes

This appendix lists the error codes, error messages, and the various indicator light and audible sequences that you may encounter during Power-On Self-Test (POST) or computer restart, the probable source of the problem, and steps you can take to resolve the error condition.

POST Message Disabled suppresses most system messages during POST, such as memory count and nonerror text messages. If a POST error occurs, the screen will display the error message. To manually switch to the POST Messages Enabled mode during POST, press any key (except F10, F11, or F12). The default mode is POST Message Disabled.

The speed at which the computer loads the operating system and the extent to which it is tested are determined by the POST mode selection.

Quick Boot is a fast startup process that does not run all of the system level tests, such as the memory test. Full Boot runs all of the ROM-based system tests and takes longer to complete.

Full Boot may also be enabled to run every 1 to 30 days on a regularly scheduled basis. To establish the schedule, recongure the computer to the Full Boot Every x Days mode, using Computer Setup.

NOTE: For more information on Computer Setup, see Computer Setup (F10) Utilities on page 11.

5 Conguring password security and

resetting CMOS

This chapter describes how to congure password security and to reset CMOS.

Preparing to congure passwords

Computer Setup (F10) Utility enables you to create setup and power-on passwords.

There are three possibilities for setting passwords:

●

Dene an administrator password only. You will need the password to enter Computer Setup (F10) Utility, but you will not need a password to start the workstation.

●

Dene a power-on password only. This password lets you start the workstation or enter the setup utility.

●

Dene both. In this case, the administrator password lets you start the workstation and enter the setup utility. The power-on password starts the workstation but does not let you enter the setup utility,

After you create both passwords, you can use the administrator 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 Main > Replicated Setup > Backup

current settings to USB device.

Resetting the password jumper

CAUTION: Stringent security is a mode where there is no physical bypass of the password function. If

enabled, removing the password jumper will be ignored. To enable this mode, change the security setting Clear Password Jumper in Password Policies to Ignore.

If you lose or forget the password when in stringent security mode, the system can only be reset by System Management Command. This is a way for HP Service and Support to provide a secure method to access the BIOS and command a password reset for a specically identied unit under the direction of the owner. This scenario may not be covered under warranty.

To prevent needing a customer service event to restore access to the system, record your congured administrator and power-on passwords in a safe place away from your computer.

To disable the power-on or administrator password features, or to clear the power-on or administrator passwords, complete the following steps:

Preparing to congure passwords 69

1. Shut down the operating system properly, then turn o the computer and any external devices, and

disconnect the power cord from the power outlet.

2. With the power cord disconnected, press the power button again to drain the system of any residual

power.

WARNING! To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to

disconnect the power cord from the wall outlet, and allow the internal system components to cool before touching.

CAUTION: When the computer is plugged in, the power supply always has voltage applied to the

system board even when the unit is turned o. Failure to disconnect the power cord can result in damage to the system.

Static electricity can damage the electronic components of the computer or optional equipment. Before beginning these procedures, ensure that you are discharged of static electricity by briey touching a grounded metal object. See the Safety & Regulatory Information guide for more information.

3. Remove the access panel.

4. Locate the header and jumper.

NOTE: The password jumper is green so that it can be easily identied.

5. Remove the jumper from pins 1 and 2.

6. Place the jumper on either pin 1 or 2, but not both, so that it does not get lost.

7. Replace the access panel and reconnect the external equipment.

8. Plug in the computer and turn on power. Allow the operating system to start. This clears the current

passwords and disables the password features.

9. Shut down the computer, unplug the power, and disconnect the external equipment.

10. Remove the access panel.

11. Place the jumper on pins 1 and 2.

12. Replace the access panel.

13. Reconnect the external equipment and plug in the computer.

70 Chapter 5 Conguring password security and resetting CMOS

Clearing and resetting the BIOS

The CMOS button resets BIOS settings to default, but does not clear the passwords or aect any of the other Security settings. On Intel systems with advanced manageability features, the CMOS button will also partially unprovision AMT.

1. Turn o the computer and any external devices, and disconnect the power cord from the power outlet.

2. Disconnect the keyboard, monitor, and any other external equipment connected to the computer.

WARNING! To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to

disconnect the power cord from the wall outlet, and allow the internal system components to cool before touching.

CAUTION: When the computer is plugged in, the power supply always has voltage applied to the

system board even when the unit is turned o. Failure to disconnect the power cord can result in damage to the system.

3. Remove the access panel.

CAUTION: Pushing the CMOS button will reset CMOS values to factory defaults. It is important to back

up the computer CMOS settings before resetting them in case they are needed later. Back up is easily done through Computer Setup. See Computer Setup (F10) Utilities on page 11 for information on backing up the CMOS settings.

4. Locate, press, and hold the CMOS button in for ve seconds.

NOTE: Make sure you have disconnected the AC power cord from the wall outlet. The CMOS button will

not clear CMOS if the power cord is connected.

5. Replace the access panel.

6. Reconnect the external devices.

7. Plug in the computer and turn on power.

NOTE: You will receive POST error messages after clearing CMOS and rebooting advising you that

conguration changes have occurred. Use Computer Setup to reset any special system setups along with the date and time.

For instructions on Computer Setup, see Computer Setup (F10) Utilities on page 11.

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 dierent 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 conguration 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 conguration might present two audio hardware choices. If you do not hear sound through the speakers, one possible

72 Appendix A Linux technical notes

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 suciently 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 specically optimized for HTT.

To enable HTT:

1. During startup, press F10 to enter Computer Setup (F10) Utility.

2. Select Advanced > System Options.

3. Set Intel Hyperthreading to Enable, and then press F10 to exit the menu.

4. Select Main > Save Changes and Exit.

5. Restart the system 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 congurations 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.

Network cards 73

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 le, execute:

/usr/bin/nvidia-xconfig

●

Recovers from a single-drive failure.

●

Serves as a good entry-level redundant system.

Conguring Intel SATA RAID

This section describes how to use Intel® Rapid Storage Technology (RST) to set up and manage SATA RAID volumes.

NOTE: These instructions apply to Windows-based systems.

You can create a RAID array from two 2.5" drives attached to SATA ports, and/or two M.2 SSDs connected to M. 2 slots. RAID cannot be created across controllers, so 2.5" SATA drives cannot be congured with M.2 SSDs. RAID must be enabled (Advanced > System Options > Congure Storage Controller for RAID is selected) to set up any RST RAID.

Intel with RST

When the Option ROM Launch Policy is set to All Legacy, the Intel SATA option ROM conguration utility runs during POST if two SATA drives are attached. If only one drive is attached, the Intel option ROM conguration utility does not run unless the drive contains RAID metadata indicating a failed RAID condition. Legacy Option ROM cannot be used to congure RAID for M.2 SSDs.

76 Appendix B Conguring RAID devices

When the Option ROM Launch Policy is set to one of the UEFI options, the Intel option ROM conguration utility does not run at POST. The user must press Esc and select 3rd Party Option ROM Management (F3) or press F3 at boot to directly launch 3rd Party Option ROM Management.

To congure M.2 SSDs for RAID, you must enable remapping in BIOS. Remapping requires the following settings in BIOS.

1. Go to Advanced > System Options, and then select Congure Storage Controller for RAID to enable

RAID.

2. Go to Option ROM Launch Policy, and then select All UEFI or All UEFI Except Video.

3. Go to Advanced > System Options > RST Remapping, and then select Enable. RST Remapping will not

appear in the BIOS menus until you perform steps 1 and 2.

Conguring the system BIOS to enable embedded SATA RAID functionality

The Z1 G3 Workstation defaults to RAID emulation mode. RAID emulation mode includes the benets of AHCI with the added benet of supporting RAID congurations. If RAID mode has been disabled, follow the steps below to change it back.

CAUTION: Changing SATA emulation modes after the operating system has been installed will prevent the

system from booting and require reinstallation of the operating system. Back up your data before changing SATA emulation mode. Disabling RAID, changing to All Legacy Option ROM Launch Policy, or disabling remapping will destroy data that was on M.2 SSDs congured for RAID.

1. During startup, press F10 to open the Computer Setup (F10) Utility. Use the mouse or arrow keys to

navigate and select options.

2. Select Advanced > System Options, and then press Enter.

3. Select Congure Storage Controller for RAID.

If the operating system was installed when RAID mode was not selected, you need to reinstall the operating system.

Press F10 to accept the settings.

Select Yes and press Enter to save changes.

4. The computer reboots.

Option ROM Launch Policy set to All Legacy

●

When RAID mode is enabled, the Legacy Option ROM will display at POST when two drives are attached to the same controller or if a single device contains RAID metadata indicating a failed or degraded RAID.

●

RAID can only be congured using SATA drives in Legacy Option ROM.

●

Remapping of M.2 NVMe SSDs is not supported so M.2 NVMe RAID cannot be congured.

Conguring Intel SATA RAID 77

Option ROM Launch Policy set to All UEFI or All UEFI Except Video

●

Option ROM conguration utilities do not display at POST. Press Esc and select 3rd Party Option ROM Management (F3) or press F3 at boot to directly launch 3rd Party Option ROM Management to congure

RAID.

●

RAID warnings and Errors display during POST, but Ctrl+I does not launch the Option ROM conguration utility.

●

A Remapping option displays in Advanced > System Options, contingent on setting the Option ROM launch policy to one of the UEFI options and successful conguration of RAID mode.

Conguring RAID volumes in Legacy Option ROM

Use the following steps to create RAID volumes on SATA drives.

1. Press Ctrl+I when prompted to enter the Intel Rapid Storage Technology Option ROM. Use the arrow keys

to navigate and select options.

Displaying of Option ROMs is enabled by default but requires that you press a key when the message “Press any key to display Option ROMs” quickly ashes.

NOTE: If only a single hard drive is attached, the utility does not execute. No message is displayed

unless the single disk contains metadata indicating a failed RAID.

2. Select 1. Create RAID Volume, and then press Enter.

3. Enter the desired RAID volume name, and then press Tab.

4. Select a level in the RAID Level eld using Up and Down arrows, and then press Tab.

5. If appropriate, press Enter to select disks. Use Up and Down arrows to highlight the disks, and Space to

6. If appropriate use Up and Down arrows to select a size in the Strip Size eld, and then press Tab.

7. Enter the desired size in the Capacity eld, and then press Tab

8. Press Enter to initiate volume creation and press Y to accept. The screen displays the newly created

volume.

9. Press Esc twice to exit the conguration utility. The system reboots.

Conguring RAID volumes in UEFI 3rd Party Option ROM

Use the following steps to create RAID volumes on SATA drives or M.2 SSDs.

1. Press F3 during POST to launch 3rd Party Option ROM Management. Use arrow keys to navigate and

select options.

2. Select Intel (R) Rapid Storage Technology and press Enter.

3. Select Create RAID Volume and press Enter. The Create RAID Volume option will only be available if

there are drives available to be congured as RAID.

4. Press Enter to change the name from the default, and then press Enter after changing the name.

5. Press the Down arrow to advance to RAID Level, and then press Enter to see valid RAID levels. Use Up

and Down arrows to select the desired type, and then press Enter.

6. Press the Down arrow to advance to Select Disks, and then use arrow keys and Enter to select each disk

to add to the array. Selected disks are marked with X.

NOTE: If remapping is enabled in BIOS, M.2 SSDs may also appear in the disk list. M.2 SSDs and SATA

SSDs cannot be included in the same RAID volume.

7. If you are creating a RAID 0 (Striped Array), you can set Strip Size. Use the Down arrow to advance to this

entry, and then press Enter and use the Down arrow to select 128KB, and then press Enter.

8. Press the Down arrow to advance past the Capacity (MB) setting. While it is possible to set capacity, HP

recommends using the defaults. The default for a RAID 1 is set to about 95% of the maximum possible capacity. This allows you to replace a failed drive with a drive of the same capacity.

9. Press the Down arrow to advance to Create Volume and then press Enter. The screen changes to show

the active RAID volumes.

10. Press Esc twice to exit the conguration utility. The system reboots.

Conguring SATA RAID in Windows

This section explains how to use the Intel Rapid Storage Technology Utility to set up and manage SATA RAID volumes in Windows. It is assumed that the Intel Rapid Storage Technology Graphical User Interface (GUI) has been installed.

1. Press the Windows key and start typing Intel. Intel Rapid Storage Technology displays in Programs.

Select

Intel Rapid Storage Technology to start the Graphical User Interface (GUI). Alternatively, in

Windows 7 you can click the Start button at the lower left corner of the screen and navigate to Intel

Rapid Storage Technology.

2. Click Yes (if prompted) to allow the application to make changes to your system.

3. Click the Create button at the top of the window.

NOTE: The Create option is only available if it is possible to create a RAID array. If you are adding a

drive to create a RAID array including data from an existing drive, you may need to shrink the size of the main partition by 5 GB to free up space for RAID metadata on the drive. The create option does not display if there is insucient space for metadata. Use disk manager to shrink the last partition on the disk. This is typically the Windows partition. If the last partition is a protected partition, shrinking the Windows partition will allow RAID creation.

4. Follow the prompts to proceed through the creation process.

5. Close the Intel Rapid Storage Technology GUI.

6. Remember to open the Disk Management snap-in to initialize and format the newly created array. The

new array is not visible until it is initialized and formatted.

Software RAID solution

This section summarizes software RAID considerations that are specic to the Linux environment, and provides links to additional conguration resources.

Software RAID considerations

The Linux kernel software RAID driver (called md, for multiple device) oers 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, 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 CPU must assume some extra loading: disk-

Conguring SATA RAID in Windows 79

intensive workloads result in roughly double the CPU 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 CPU performance are very well balanced and already near bottleneck levels, this additional CPU overhead can become troublesome.

Hardware RAID oers advantages because of its large hardware cache and the capability for better scheduling of operations in parallel. However, software RAID oers more exibility 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 oer 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 aected by the software conguration, determines the location of the any bottleneck is in the system.

Several RAID levels oer 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.
