AD248A HP Integrity rx2660 8 Port SAS Controller Options

AD248A is the 8 port SAS controller option of the HP Integrity rx2660. Option #106 is the embedded SAS RAID controller. Options #130, #530 and #540 are the HP 8 Port SAS Smart Array P400 controller card, which sits in a dedicated PCI Express slot with up to 1.3 GB/s of sustained bandwidth.

The embedded controller (#106) is supported by HP-UX, OpenVMS and Linux and is not supported by Windows. It supports a maximum of two RAID 1 volumes (2×2 disks) and a global hot spare disk, which makes five disks in RAIDed arrays. The remaining three of the eight supported disks can be accessed normally but not configured for RAID. MirrorDisk/UX is available for software mirroring on all disks of HP-UX systems.

The Smart Array P400 card supports RAID 1, 5 and 6, and all eight disks can be configured in any combination. RAID 1 needs two identical disks, RAID 5 three and RAID 6 four. The card is required on all Windows systems and is optional on HP-UX, OpenVMS and Linux systems. It comes with a battery backed write cache (BBWC) and 256 MB of memory, and factory configuration of a RAID set is available.

Each of the eight ports connects to one SAS disk over its own 3 GB link, and the cables to the internal disks ship with the system. The spare numbers for the P400 card are 405831-001 for the controller board, 405836-001 for the 256 MB BBWC memory module, 398648-001 for the battery module, 409124-001 for the battery cable and AB419-67008 for the PCI expansion board.
