3 Operating systems and devices supported Operating systems supported HP RAID supports 32-bit and 64-bit versions of Microsoft® Windows® XP Professional (SP1, SP2, and SP3), Windows Vista® (SP1 and SP2), and Windows 7 operating systems. Devices supported This section describes the devices supported for RAID migration, including the SATA drives, computers, and docking station. Device support is summarized in the following table and then explained in more detail below the table. External USB SATA drives connected to the computer or docking station cannot be used for migrating to RAID. RAID 0 RAID 1 Recovery RAID 5 Primary and Upgrade Bay SATA hard drives in the computer Primary and secondary bay SATA hard drives in the computer Yes Yes Yes Yes Yes Yes No Yes Docking station hard drive or eSATA hard drive attached to computer No No Yes No HP SATA drive option kits HP offers SATA drive option kits for the computer Upgrade Bay and the docking station's SATAswappable bay to support RAID migration. For optimal RAID performance, it is recommended that both drives have the same speed. However, supported HP Business computers allow drives with different speeds to be used in a RAID volume. Drives of different capacities are also supported for RAID migration, as long as the capacity of the secondary (recovery) drive is equal to or greater than that of the primary drive. For example, if the primary drive is 200 GB, then at least a 200-GB drive is required in the Upgrade Bay to create a RAID volume. If the capacity of the secondary drive is larger than that of the primary drive, the excess capacity of the secondary (or third) drive will not be accessible. If, for example, the primary drive is 160 GB and the secondary drive is 250 GB, only 160 GB of the secondary drive will be usable in a RAID configuration. Therefore, for optimal use, it is recommended that both drives have the same capacity. Operating systems supported 7

HP SATA drive option kits
HP offers SATA drive option kits for the computer Upgrade Bay and the docking station's SATA-
swappable bay to support RAID migration. For optimal RAID performance, it is recommended that
both drives have the same speed. However, supported HP Business computers allow drives with
different speeds to be used in a RAID volume.
Drives of different capacities are also supported for RAID migration, as long as the capacity of the
secondary (recovery) drive is equal to or greater than that of the primary drive. For example, if the
primary drive is 200 GB, then at least a 200-GB drive is required in the Upgrade Bay to create a RAID
volume. If the capacity of the secondary drive is larger than that of the primary drive, the excess
capacity of the secondary (or third) drive will not be accessible. If, for example, the primary drive is
160 GB and the secondary drive is 250 GB, only 160 GB of the secondary drive will be usable in a
RAID configuration. Therefore, for optimal use, it is recommended that both drives have the same
capacity.
