Chapter 2 – Hardware Installation

The RAID system controller board already implement a 512Mb memory for

the propose of Parity bit to support the ECC feature. There is no need to install

the SODIMM with parity.

Architecture of supported SODIMM:

SDRAM Architecture

 512 MB  16 (32M x 8)

 256 MB  16 (16M x 8), 8 (32M x 8) or

 8 (16M x 16)

 128 MB  16 (8M x 8), 8 (16M x8), 8 (8M x16) or

 4 (16M x 16)

 64 MB  8 (8M x 8), 8 (4M x 16) or

 4 (8M x 16)

 32 MB  4 (4M x 16)

RAID SYSTEM is normally supplied with 64MB (PA-08P/SA-08P) and 128MB (SA-16P/

PA-16P) DRAM installed.

There's no set formula to determine how much cache memory to use, but as a

general rule, a workstation, with mostly very large files, such as for audio or

video editing and playback, graphics or CAD files, can benefit from a large

cache. File servers, with multiple random access of varying file size, generally

have little or no performance improvement with additional cache.
