RH8100 V3 RAID controller cards

32

The RAID controller cards support RAID array configuration, RAID state migration, and RAID configuration memory. Observe the following rules when configuring RAID controller cards for the RH8100 V3:
? One or two RAID controller cards are required.
? RAID controller cards of different models cannot be used on the same server.
? The RAID controller card model varies with the front I/O module.
? RAID-1 belongs to compute module 1, and RAID-2 belongs to compute module 5. A RAID controller card is unavailable if the compute module it belongs to is not installed.

RAID controller cards supported by different I/O modules:
1. FM-A: RU320BC (LSI SAS2208), RU130 (LSI SAS3008), and RU430C (LSISAS3108)
2. FM-B and FM-C: SR430C (LSI SAS3108)

RAID card function description:
? RU320BC (LSI SAS2208): supports RAID 0/1/5/6/10/50/60, and an iBBU or supercapacitor for data protection.
? RU130 (LSI SAS3008): supports RAID 0/1/1E/10 and does not support a battery for data protection.
? RU430C/SR430 (LSISAS3108): supports RAID 0/1/5/6/10/50/60, and a supercapacitor for data protection.

Necessity of configuring RAID arrays for a RAID controller card
If the LSISAS1078, LSISAS2208, or LSISAS3108 RAID controller card is used, the disks can be recognized by the system only when they are in RAID arrays. If the LSISAS1068, LSISAS2308, or LSISAS3008 RAID controller card is used, the disks can be used as individual disks for OS installation, if they are not in RAID arrays.
