Installing and removing the ROMB (RAID on Motherboard) activation key and dedicated RAID memory
Functionality for RAID levels 5, 10, and 50 is enabled by using the optional Intel RAID Activation Key
Important | The IOP332 ROMB option in BIOS Setup is grayed out unless a valid | |
Intel RAID Activation Key and compatible RAID memory are present. | ||
|
If IOP ROMB is enabled, the system boots using the ROMB option ROM. In this case, the SCSI channels are used by the ROMB solution to enable RAID 5, 10, and 50 functionality. If the RAID Activation Key and RAID DIMM are not present, the system boots in SCSI mode and the IOP332 ROMB option in system BIOS will be grayed out.
The onboard RAID (levels 1 and 2) and the ROMB RAID (levels 5,
Important 10, and 50) are mutually exclusive solutions. Only one of the two may be used at a time. A RAID array (using one or more drives) transfer from one mode to the other is not supported.
Your server’s system board includes a RAID cache memory socket. This DIMM is not shared with main memory and is for exclusive use as RAID cache for ROMB functionality. The ROMB subsystem supports one 128 MB, 256 MB or 512 MB DDR400
To install the RAID activation key and RAID DIMM:
