Cisco UCS B200 M4 Blade Server

CONFIGURING the SERVER

STEP 4 CHOOSE RAID CONTROLLER AND DISK DRIVE BAYS

The UCS B200 M4 can be ordered with or without the Cisco FlexStorage RAID controller with disk

drive bays (local storage subsystem).

There is no RAID or local storage controller or drive bays included (embedded) with the B200 M4

server. Therefore, a Cisco FlexStorage RAID controller with drive bays must be purchased in

order to support any (1 or 2) local hard disk drives (HDDs) or solid state drives (SSDs). Either

Cisco FlexStorage RAID controller supports RAID 0 and 1 as well as non-RAID’ed configurations.

For servers that will not need any local HDDs or SSDs (for example, for booting from SAN), you

can order the server without a Cisco FlexStorage RAID controller with disk drive bays; however

be sure to select the Cisco FlexStorage blanking panels.

The ordering information is listed in Table 8.

See Figure 4 on page 17 for a top view of the B200 M4 server with and without the Cisco

FlexStorage SAS RAID controller and drive bays. See Figure 5 on page 17 for a front view of

these configurations. When no drive bays are installed, blanking panels must be installed.

2. The flash-backed write cache provides RAID controller cache protection using NAND flash memory and a

supercapacitor. In the event of a power or server failure, cached data is automatically transferred from the

RAID controller DRAM write cache to flash. Once power is restored, the data in the NAND flash is copied back

into the DRAM write cache until it can be flushed to the disk drives.
