Cisco UCS C240 M3 High-Density Rack Server (Small Form Factor Disk Drive Model)
CONFIGURING the SERVER
27
Approved Configurations
The C240 M3 SFF server can be ordered as a UCSC-C240-M3S2 (16-drive backplane with no SAS expander) or
a UCSC-C240-M3S (24-drive backplane with SAS expander).
■ ROM5 and ROM 55 embedded RAID upgrade options support up to 8 internal drives with the
16-drive backplane and are not supported for the 24-drive backplane.
■ Mezzanine cards (UCSC-RAID-11-C240 and UCSC-RAID-MZ-240) support up to internal 8 drives
for the 16-drive backplane, and up to 16 internal drives for the 24-drive backplane.
■ The SAS 9271-8i and 9271CV-8i PCIe cards support up to 8 internal drives each for the
16-drive backplane, and up to 24 drives for the 24-drive backplane. For the UCSC-C240-M3S2
server, a two-CPU system is required to support two 9271-8i or 9271CV-8i PCIe cards and up
to 16 drives. For the UCSC-C240-M3 server, a single 9271-8i or 9271CV-8i PCIe card supports
up to 24 drives in either a one-CPU or two-CPU system.
■ The Cisco Nytro MegaRAID 200 GB card supports up to 24 internal drives for the 2-CPU
24-drive backplane only.
■ LSI MegaRAID SAS 9285CV-8e and 9286CV-8e PCIe cards support up to 8 external SAS ports
(240 external drives).
See Table 9 for a summary of the supported RAID configuration options.
NOTE: For the 16-drive backplane 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: As shown in the table, the NYTRO MegaRAID 200 RAID controller is supported
only in slot 3 of a 2-CPU 24-drive backplane system (UCSC-C240-M3S).
