Cisco UCS C240 M3 High-Density Rack Server (Small Form Factor Disk Drive Model)

CONFIGURING the SERVER

STEP 4 SELECT RAID CONFIGURATION

The RAID controller choices are:

(1) Embedded RAID (on motherboard) (not supported in 24 HDD backplane systems)

(2) Mezzanine RAID controller cards (not supported in 1-CPU systems)

(3) 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: For the UCSC-C240-M3S2 (16-drive server), 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: The UCSC-C240-M3S (24-drive server) does not support embedded RAID,

which is normally installed on the motherboard and does not consume a PCIe slot.

The only RAID support available for the 24-drive version is through a PCIe RAID

controller or a mezzanine card.

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 Nytro MegaRAID 200 GB PCIe RAID controller = 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).
