Hot-Swap Sas/Sata Backplane; Sas/Sata Backplane Layout - Intel SR1625UR Technical Product Specification

Intel® Server System SR1625UR TPS
7.2.2.4.2 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 DDR2-667 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.

7.2.2.4.3 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.

SAS/SATA Backplane Layout

The hot-swap backplane installs on the back side of the hot-swap drive bay inside the system.
Alignment features on the system and backplane assembly make for easy tool-less installation.
For instructions on installing and removing the backplane, see the Intel
SR1625UR Service Guide. The following diagram shows the layout of components and
connectors found on the board.
