Alright, I've got a software RAID 5 set up on a server that is only handling the array.
Server specs: SuperMicro H8DAE, Dual Opteron 275's, 12GB ECC RAM, 3x1TB seagates in RAID 5 on a SM PCI-X card.
The problem is after about 2GB is transferred over at gigabit speeds (~95MB/s due to source limitations) the speed drops sharply to ~50MB/s and then keeps dropping slowly after that.
MTU is set to 9000 on the server, 9014 on the workstation (PCI-e Intel gigabit NIC), switch is an HP procurve 1400-8G
Is there any way to fix the problem, maybe by throwing all of the resources on the server at it? I'm assuming that the array is filling a 2GB buffer of system ram and dropping off in speed, so I'd like to give it full access to the four cores and 12GB of RAM.
