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

SUPPLEMENTAL MATERIAL

Low-Voltage DIMM Considerations

The C240 M3 server can be ordered with dual-voltage (1.35 V) DIMMs. Note the following considerations:

■ Low-voltage DIMMs within the server must have the identical manufacturer, type, speed,

and size.

■ Low-voltage DIMMs and standard-voltage DIMMs can be mixed in the same server. Note that

this causes the system BIOS to default to standard-voltage operation (Performance Mode).

That is, the server cannot operate in Power Saving Mode unless all DIMMs are low-voltage

DIMMs.

■ CPUs that have a maximum memory frequency less than 1333 MHz support low-voltage

DIMMs operating in Power Saving Mode only, and do not support Performance Mode.

RAID Summary

The C240 M3 LFF server has a 12-drive backplane with a SAS expander.

■ No embedded RAID support

■ Mezzanine card (UCSC-RAID-11-C220) supports up to 12 drives

■ Mezzanine card (UCSC-RAID-MZ-220) supports up to 12 drives

■ 9266-8i and 9266CV-8i PCIe cards support up to 12 drives

Notes . . .

1. Configurations for optimum memory performance are highlighted in yellow.

NOTE: If you do not select a mezzanine card or a plug-in PCIe RAID card you will

have no RAID at all since the embedded SATA-only RAID controller that supports up to

four SATA-only drives (RAID 0, 1, 10) is not compatible with a SAS expander.
