Why do I have slow network performance on HP DL360 G5 with MSA 30 attached

I have been running a new HP DL360 G5 with a MSA 30 DAS attached, running W2K3 SP2. The MSA has 8 x 300GB 15K U320 Drives

I have teamed the two internal 1GB network cards together and this is where the problems started, I had an issue where it was taking for ever to save anything to this server so I did a bit of research and installed some HP and MS patches (KB948496) that helped but the speed is now becoming an issue again.

The drives are setup in a RAID 5 to give me 2TB which is shared over the network via 10 shares for different departments; there is only 900GB of data.

Now the real issue is when I am doing any maintenance on the server e.g. resetting permissions on folders, moving data from one folder to another the whole of the network grinds to a halt and everyone who is using the server shares freeze until my processes have finished (approx 60 users over CAT5)

What will be causing this issue and how do I resolve it? Is it to do with the teamed network ports? Do I need to add more network cards and increase the team? Or is is an issue with W2K3?

Any help is much appreciated.

The first place I will start to look is how you teamed your NICs.  Did you team via the HP software in conjuction with your network switch for 803.2ad or did you select one of the others as show in the screenshot.

I have Automatic set.

I am running 3com 4200g switches all with default settings.

Before this new server I had a DL 380 G4 running the same with no speed issues or freezing problems.

Can you then please login to your switches management console and set the ports for your HP NICs to 1000 Full Dulpex. I am thining you have some port duplex mismatching going on...

I will give this a go but is this why when I do tasks on the server like permissions everyone freezes

Sorry, this did not work, when I perform the permission task (adding security group to 200 subfolders total size = 20GB) on the server it freezes the network still.

Any other ideas pleas.

Have you tried making the changes from the server's console and does the same effect occur?
