HP File Server Optimization Tips

I have Hyper-V running on a powerful server and I have one of the virtual machines mounted to an ISO hosted on a fileshare on an HP DL380 G4, lets call it fileserver1. The bottleneck in the whole setup is fileserver1.

Fileserver1 is setup with a RAID5 array that we've been using for about 4 years i guess. Its been a great fileserver to about 40 staff members. Running Windows Server 2003 Standard with 2x Xeons @3.4GHz and 1GB RAM. All servers have 1GB NICs connected to GB switch. It is a really underutilized server averaging about 5% in every performance counter in perfmon. With the iso file mounted to the virtual machine on the other server, fileserver1's Pages/sec counter maxes out which is apparently the bottle neck.

My questions
1. How can I reduce this bottlleneck? I'm not sure if I should add more RAM becuase i've heard fileserving is not RAM intensive and this is the only time pages/sec even gets close to maxing out.
2. Is there a set of best practices or suggestions that will allow me to optimize the performance of fileserver1?

I notice one thing a little wile ago if you disable receive side scaling on the network card your network will work faster.
this teak was made in a DL380 G5. But you can try it and test it.

Thanks for the tip but the network doesnt seem to be maxing out at all
1) Check task manager and see if All the RAM is being used in the commit charge Section.

If total or peak is > 1 GB then you need more RAM

You should use perfmon to monitor more counters to see the exact issue

I hope this helps !

Under commit charge total is bouncing around 366,000 and peak is 1,169,504 so if theres a 1GB ram already in there, and commit is only around 360MB, doesnt that mean theres plenty of RAM?

Physical ram says 570MB available

Any suggestions for improving this bottleneck or best practices as I requested?
Well the problem is that your peak is over 1 GB, which means that at some point you were doing a lot of paging which drastically slows things down.

You should run perfmon in log mode to see when this is happening or simply add 1 Gb more RAM

I hope this helps !
