Re: [Xen-users] iscsi vs nfs for xen VMs

[Jia Rao <rickenrao@xxxxxxxxx>]

Thank you very much for the prompt replies.

My intention of moving to iscsi is due to pure performance purpose.
The physical hosts and the storage server are connected through a 1G switch. The storage server uses raid-5 disk array.
My current testing using iozone within VMs on both iscsi and nfs produced similar performance results for sequential and random read.

I was told it will make a big difference if there are 10-15 VMs sharing the storage server. In my case, I have 8-10 VMs.

Any experience with a larger number of VMs in both nfs and iscsi?

Jia.
