Technical Product Specification

Peripheral and Hard Drive Subsystem Intel® Server System SR2625UR TPS

Intel order number E46130-010 Revision 1.8

6.4.2.4.1 Intel

RAID Activation Key

The Intel

RAID Activation Key enables the full intelligent SAS Hardware RAID solution. The

activation key plugs directly into a connector (J1A10) on the midplane board. With no RAID

activation key installed, only SAS Software RAID levels 0, 1, and 10 are supported.

6.4.2.4.2 Intel

RAID Cache support

To further enable support for hardware RAID, the active midplane provides a 244-pin mini-

DIMM connector (J8C1), supporting a single registered ECC non-parity DDR2-400 MHz Mini-

DIMM to provide Intel

RAID cache. Supported mini-DIMM capacities range from 128 MB

to 1 GB.

Note: For a list of Intel

validated mini-DIMMs, use the Server Configurator Tool available at

http://serverconfigurator.intel.com/default.aspx.

6.4.2.4.3 Intel

RAID Smart Battery Backup Module

With an Intel

RAID Smart Battery Backup module installed, data loss is prevented when data

is still present in the RAID Cache Module and power is unexpectedly lost. Depending on the

cache module capacity used, the battery backup unit can provide 48 to 72 hours of battery

backup power to allow data stored in the RAID cache to be processed. A 2x10 connector (J9A2)

is used to attach the battery backup unit to the midplane. For details, see Table 31.
