Recommendations for installing more RAM

The AXIS StorPoint CD+  is shipped with 32 MB of RAM. It's possible  to install additional RAM module of either 64 MB, 128 MB  or 256 MB size. The additional RAM should be a standard 168 pin SDRAM DIMM  module:  

  • SDRAM
  • PC100 or PC133
  • CL2 or CL3 (CL2 preferred)
  • 64 bits of data
  • Unbuffered
  • Non parity (Non ECC)
  • +3.3 V
  • Refresh 4k/64 ms
  • SPD (Serial Presence Detect)

Normally the standard 32 MB are sufficient, but in the following situations it could be of use to install additional RAM:

Typical situation 32 MB onboard 64 MB expanded 128 MB expanded 256 MB expanded
Large files that are accessed repeatedly do not fit into the current RAM cache Repeated use of up to ~10 MB files Repeated use of up to ~40 MB files Repeated use of up to ~100 MB files Repeated use of up to ~200 MB files
A large number of users work concurrently and repeatedly with different files on the same StorPoint CD+ ~5 concurrent users* ~10 concurrent users* ~20 concurrent users* ~50 concurrent users*
Multiple CDs are cached on the hard disk Up to ~150 CDs Up to 255 CDs N/A N/A

By accessing the statistics page of the StorPoint Web administration,  you will be able to see the number of currently attached users and time  elapsed since the latest access.

Note: If a module is connected, the mounted 32 MB SDRAM will become inactive.

Please refer to the user documentation for RAM installation procedures.  Functionality with the following RAM modules has been verified:
