Hi everyone !
Here is my setup:
2 servers (Hyper-v / Xeon E5620 / 16Go each) running in cluster. Connected to a QNAP TS-859U+ NAS thru a ProCurve 6108 with 2x1GB trunked ports.
There are 11 guest VMs all running at very poor speed. For instance it takes up to 1 hour to complete less than 10 Windows Server updates.
When I'm checking the switch or the NAS status, it appears that bandwidth usage is extremely low: I've got 1-4% usage top on both ports of the switch. And no more than 4-5Mo/s of read / write operations on the QNAP ressources monitor.
I really don't understand what's going wrong with this quite simple setup so I hope you guys can help me out !
Thanks everyone and sorry for that bad english you have to read...
