The Dell SAS controller probably have on-board write cache which helps with
performance (write commit).
Based on my limited understanding, the 7110 does not have write cache on SAS
controller.

Hi all,
(down to the wire here on EDU grant pricing :)

The price is sure right. I'd use them in a mirrored, cold-failover
config.
I'd primarily be using them to serve a vmware cluster; the current config
is two standalone ESX

We tried using the 7110 with XEN Server 5 over iSCSI and NFS. Nothing seems to
solve the slow write problem. Within the VM, we observed around 8MB/s on

Both iSCSI and NFS are slow? I would expect NFS to be slow, but in my iSCSI

There's a configuration issue in there somewhere. I have a ZFS based
system serving up to some ESX servers working great with a few
exceptions.
First off perf was awful, but there was some confusion on how to
optimize network traffic on ESX so I installed a fresh one using only

With XenServer 4 and NFS you had to grow the disks (modified manually from
thin to fat) in order to get decent performance.

Hey Lawrence,
Make sure you're running the latest software update. Note that this forumn
is not the appropriate place to discuss support issues. Please contact your
