Subject: Virtio on infiniband HW expected performance?
Date: Fri, 20 Nov 2009 07:52:33 +0100 [thread overview]
Message-ID: <4B063CB1.8080008@shiftmail.org> (raw)
Hi all
we are evaluating the purchase of infiniband hardware together with
Nehalem-based servers, for KVM use.
What performance can we roughly expect with virtio-net over infiniband
hardware?
Communication would be primarily for these 2 purposes:
1- VM to a HN: primarily NFSv4 imports from the fileserver (a HN) to the
VMs, for the files shared by multiple VMs.
2- HN to HN: fileserver serving VM disk-images via NFSv4 to the HN which
is running KVM.
What performances can I roughly expect in these 2 cases? Also, for
evaluating case #2: what is the performance of virtio-blk?
Our VMs would be 70% linux, 30% windows.
Thank you
Asdo
