Cisco UCS C240 M4 High-Density Rack Server (Small Form Factor Disk Drive Model)

CONFIGURING the SERVER

Select RAID Options

Select as follows (these choices are dependent on the backplane used (24-drive, 16-drive, or

8-drive backplane)):

■ For the 8-drive backplane system only, select the embedded software RAID 5 key upgrade

option for internal drives (see

Table 8), or

■ For all systems, select the Cisco 12G SAS modular RAID controller for internal drives plus

optional flash-backed write cache (FBWC) (see

Table 9 on page 26), or

■ For all systems, select dual controllers:

— One Cisco 12G modular RAID controller for internal drives plus optional flash-backed

write cache (FBWC), and

— One Cisco 9300-8E 12G SAS controller for external drives (see Table 9 on page 26).

Table 8 shows the product ID for the C240 M4 server entry-level RAID solution. This RAID option is

accomplished with embedded software that supports a limited number of drives, operating systems, and

virtualized environments. For a more comprehensive enterprise RAID solution, choose the Cisco 12G SAS

modular RAID controller listed in

Table 9 on page 26.

NOTE: The Cisco 12G SAS modular RAID controller can be ordered with or without an

optional FBWC. The FBWC backs up the RAID controller write cache. The FBWC is

available in 1 GB, 2 GB, or 4 GB sizes. See

Table 9 on page 26 for details.

NOTE: For all valid combinations of embedded RAID and internal/external RAID

controller combinations, see

RAID Details, page 68.
