CONFIGURING the SERVER
STEP 4
SELECT RAID CONFIGURATION
The RAID controller choices are:
(1) Embedded RAID (on motherboard)
(2) Mezzanine RAID controller cards (not supported in 1-CPU systems)
(3) PCIe RAID controller
Cisco can provide factory-configured RAID systems depending on the RAID controller chosen and
the number of drives ordered. Factory-configured RAID options are listed with each RAID card
description.
NOTE:
If you do not select a mezzanine card, a PCIe RAID controller, or one of the
embedded RAID upgrade options, you will have an embedded SATA-only RAID
controller that supports up to four SATA-only drives (RAID 0, 1, 10)
NOTE:
When creating a RAID volume, follow these guidelines:
■
Use the same capacity for each drive in the volume
■
Use either all SAS drives or all SATA drives
■
Use either all HDDs or all SSDs
NOTE:
The number of RAID groups (virtual drives) supported per controller is as
follows:
■
Embedded RAID = 8
■
LSI MegaRAID 9271-8i or 9271CV-8i RAID controller card = 64
■
LSI MegaRAID 9285CV-8e or 9286CV-8e RAID controller card = 64
■
Cisco UCSC RAID SAS 2008M-8i Mezzanine Card = 16
NOTE:
The RAID configuration options listed in
Table 8 on page 24
are not available
if you choose embedded RAID (in this case, you must configure RAID yourself using
separate software).
