Hi,
We are trying to deploy VM on NFS but it is giving us slow network performance while transferring the data from one nfs datastore to another nfs datastore hosted on 2 different filers, mainly while transferring multiple vmdk files simultaneously. Both the filers and esx servers are on same network and data transfer rate is around 7 mbps.
I have tried doing some tests and noticed if we transfer one VMDK at a time between the filers the performance is around 22 mbps whereas if we do the data transfer between same pair of filers and with same volumes using ndmpcopy and performance goes upto 130 mbps. Even when migrating the vmdks from DMX to Netapp we are getting only upto 40 mbps.
We are using all gbic connection with ESX version 3 in our environment.
Please let me know if you need some more information.
