system requirements for storage node
Hey people,
I have looked up the requirements in system ressources for storage node. But can someone tell me what is the real systems requirements for storage nodes ?
For the past month we have problems with our storage node hanging for no reason. That is until I put another 2GB of memory into my SN and everything work like a charm.
Pure luck or the SN is ressource hungry.

It may be interesting if you post the spec of your storage nodes, the amount of throughput you are hoping to get and the number and type of drives you are hoping to drive...

My storage node is an IBM System x3550 ( dual core 3GHZ, 6GB of memory) running windows 2008 STD 64 bits. 2 GB NIC Card and 1 FC HBA.
My SN service 2 tape libaries (quatum i50 (3 tape drive) & quatum scalar50 (2 tape drive) ) in DDS mode.
As for throughput I never paid attention to it. Cause mu SAN admin takes care of it.
I like to know why it is memory hungry. My understanding of Storage node is that the only demanding resource should be CPU and SAN throughput and not memory no ?
Why should we need 16GB+ of memory on a storage NODE ?

a)If other applications are running concurrently with the backup on the storage node, they impose an additional load on the system. Heavy swapping or paging activities indicate that the server is CPU or memory-bound.
b)When a NetWorker server is saving a large number of save sets, such as 500 or more, memory consumption can reach high values. In this event, the parallelism may need to be lowered.
For best results, install the maximum amount of memory that your computers will sustain, especially for the NetWorker server and storage nodes.
