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 |
* Significantly more users can have the CDs
mapped. "Concurrent users" refer to users that are
actively accessing CD data at the same time.
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.
