Intel® Server System SR2500AL 

AXXRAK18E) and installation of a Mini-DIMM for Intel RAID Cache support. To protect from 
data loss during an unexpected power loss event, an Intel

®

 RAID Smart Battery Backup module 

(AXXRSBBU3) is also supported. Hardware RAID levels supported include 0, 1, 5, 10, and 50. 

The Intel

®

 RAID Activation Key enables the full intelligent SAS Hardware RAID solution 

engineered around the Intel

®

 80333 I/O Processor @ 500MHz.  The activation key plugs directly 

in to a connector (J1A10) on the mid-plane board. With no RAID activation key installed, only 
SAS Software RAID levels 0, 1, and 10 are supported. 

To further enable support for hardware RAID, the active mid-plane 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. Mini-DIMM capacities supported range from 128MB to 1GB.  

Note: See the Intel

 Server Board S5000PAL Tested Memory List for a list of Intel validated 

mini-DIMMs. 

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 mid-plane. See Table 24. Active Mid-plane SAS RAID 
Battery Backup Connector Pin-out for details.
