SAN16 Performance

[Andrew Phoenix]

I am running a small SAN with about 10 servers, 5 of which have 2gb redundant paths through 2 switches to an MSA1000, 2 servers on 1gb via one switch to RA4100 and 3 servers on 1gb via the other switch to an RA4100. This is a configuration that works OK.

However I am monitoring performance via the switches and the stats that they are providing would suggest very poor performance. I also tried performing Disk-to-Disk backups and experienced very bad performance. Backup to tape was giving me 1GB/min, but backup to disk was giving me 1GB/hour.

I am in need of assistance, can anybody help me get a clearer idea of what is going on here...


Many Thanks

Andrew

Andrew,
Do you have realtime virus protection running.

Do you mean on the servers...? If so the answer is no. I have attached a copy of the performance stats provided by the switch, hopefully you are in a position to help.

As you can see from the stats the figures shown are about at their peak, which seems to be far smaller than I would have expected. I'm beginning to think that maybe my expectations are wrong, in which case please correct me.

Have you come across any useful resources that I can use to help me in my quest...?



Many Thanks

Andrew

I am in a position to help you.
I will need more information about you configuration.

For instance,
OS
HBA
Backup App.

If you have time the tech support from CLI or a description on how your MSA drives are carved.
