Cisco UCS Cisco UCS C220 M3 High-Density Rack Server (Large Form Factor Hard Disk Drive Model)

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) Plug-in PCIe RAID controller cards

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 plug-in PCIe RAID card, 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 9266CV-8i RAID controller card = 64

■ LSI MegaRAID SAS 9266-8i RAID controller card = 64

■ LSI MegaRAID 9285CV-8e RAID controller card = 64

■ Cisco UCSC RAID SAS 2008M-8i Mezzanine Card = 16

NOTE: The RAID configuration options listed in Table 7 on page 18 are not available

if you choose embedded RAID (in this case, you must configure RAID yourself using

separate software).
