Maximum hard drive configurations

This section lists the maximum number of hard drives supported on HP workstations for RAID

configurations.

NOTE: This section applies to internal workstation configurations that do not use add-in cards and

JBODs.

TIP: Use the table values to determine workstation-specific maximum number of hard drives as

discussed the sections below.

Configuring SATA RAID devices

This section describes how to use the Intel Matrix Storage Manager option ROM Configuration utility to

set up and manage SATA RAID volumes.

The following SATA RAID configurations are supported on this workstation:

●Up to the workstation-specific maximum number of internal SATA hard disk drives and eSATA

drives (if you use an optional eSATA bulkhead cable)

●Intel Matrix Storage Manager (IMSM) for Windows

If only a single HDD is attached, the Intel Matrix Storage Manager option ROM does not execute.

Associated messages are not displayed.

The Intel SATA AHCI BIOS executes when you select RAID+AHCI for the SATA emulation mode. This

BIOS is only used to support serial-attached optical drives.

This section does not apply to configuring SATA RAID in the Linux environment. For Linux SATA RAID,

refer to the Software RAID in Linux Workstations section in the HP Workstations for Linux User Guide

at http://www.hp.com/support/linux_user_manual.

Attaching SATA HDDs

Attach the required minimum number of SATA hard drives for the desired RAID level:

●RAID 0: two or more hard drives

●RAID 1: only two hard drives

●RAID 5: three or more hard drives

●RAID 10: only four hard drives

Configuring SAS RAID devices

Supported configurations

The following RAID configurations are supported on this workstation:

NOTE: This section does not apply to configuring SAS RAID in the Linux environment. For Linux SAS

RAID information, including supported configurations, refer to Installing and Configuring SAS Hardware

RAID on HP Linux Workstations at http://www.hp.com/support/xw8600_manuals.

●Up to the workstation-specific maximum number of internal SAS hard disk drives

●LSI MegaRAID Storage Manager (MSM) for Windows

The following RAID configurations are supported on this workstation:

●RAID 0 – Striped disk array (IS)

◦Two drive minimum

◦Improved I/O performance

◦No fault tolerance

●RAID 1 — Mirrored disk array (IM)

◦Two drives

◦100% redundancy

◦Can recover from single drive failure

◦Improved read performance

●RAID 1E (IME)

◦Three drives minimum

◦Can be an odd number of drives

◦Can always recover from a single drive failure and, in some cases, can recover from two drive

failures

ENWW Configuring SAS RAID devices

SAS RAID 0 configuration

Use the following procedure to configure an Integrated Striped (IS) volume with the BIOS-based

configuration utility. The procedure assumes that the system has the required disk and disk controllers.

1. Start the LSI Corporation Configuration Utility. During BIOS start up, you are prompted to Press

Ctrl-C to start LSI Corp. Configuration Utility.

2. On the Main menu of the BIOS-based configuration utility, use the arrow keys to select an adapter.

3. Press Enter to go to the Adapter Properties screen.

4. On the Adapter Properties screen, use the arrow keys to select RAID Properties, and press

Enter to go to the New Array Type screen.

5. In the Select New Array Type screen, use the arrow keys to select Create IS Volume. Press

Enter to go to the Create New Array screen.

6. In the Create New Array screen, use the arrow keys to select the first disk for the IS volume. Then

use the arrow keys to move to the RAID Disk column for this disk, and press Space and +or -to

select Yes as the value for this column.

If partitions are defined on the selected disk, a message appears warning you that data on the disk

will be lost when the striped volume is created.

7. Press Mto migrate, or Dto delete the data on the drive.

8. To select additional drives for the striped volume, up to the workstation-specific maximum number,

repeat the previous steps.

9. When all drives are selected, press Cto create the array once. Use the arrow keys to move to

Save changes then exit this menu and press Enter.

10. When the new array is created, the Adapter Properties screen appears. Press Esc twice and

select Exit.

SAS RAID 1 configuration

Use the following procedure to configure an Integrated Mirroring (IM) volume with the BIOS-based

configuration utility. The procedure assumes that the system has the required drives and drive

controllers.

1. Start the LSI Corporation Configuration Utility. During BIOS start up, you are prompted to Press

Ctrl-C to start LSI Corp. Configuration Utility.

Enter to go to the New Array Type screen.

5. In the Select New Array Type screen, use the arrow keys to select Create IM Volume. Press

Enter.

6. To configure a two-disk mirrored volume with an optional hot spare disk:

a. In the Create New Array screen, use the arrow keys to select the primary disk for the IM volume

(the disk with the data you want to mirror.)

b. Use the arrow keys to move to the RAID Disk column for this disk and press Space to

select Yes as the value.

If partitions are defined on the selected disk, a message appears warning you that data on

the disk will be lost when the mirrored volume is created.

c. Press Mto migrate or Dto delete the data on the drive.

d. The value in the Array Disk column changes to Primary.

Use the arrow keys to select the secondary (mirrored) disk for the IM volume, and then

select Yes as the value for the Array Disk column.

If partitions are defined on this disk, a message warns that data on the disk will be lost when

the mirrored volume is created.

e. Press Delete to confirm erasing data from the disk, or press any other key to deselect the

disk.

7. When all drives are selected, press Cto create the array once. Use the arrow keys to move to

Save changes then exit this menu and press Enter.

8. When the new array is created, the Adapter Properties screen appears. Press Esc twice and

select Exit.

maximum number of drives:

a. In the Create New Array screen, use the arrow keys to select the first disk for the IME volume.

b. Use the arrow keys to move to the RAID Disk column for this disk, and then use the +or -

keys to select Yes as the value.

If partitions are defined on the selected disk, a message appears warning that the data on the

disk will be lost when the mirrored volume is created.

c. Press Mto migrate, or Dto delete the data on the drive.

d. Use the arrow keys to select the next disk for the IME volume, and then select Yes as the

value for the Array Disk column.

If partitions are defined on this disk, a message warns you that data on the disk will be lost

when the mirrored volume is created.

e. Press Delete to confirm erasing data from the disk, or press any other key to deselect the

disk.

f. Repeat the previous steps to select up to the workstation-specific maximum number of drives

for the IME volume, including configuration of a hot spare.

7. When all drives are selected, press Cto create the array once. Use the arrow keys to move to

Save changes then exit this menu and press Enter.

8. When the new array is created, the Adapter Properties screen appears. Press Esc twice and

select Exit.
