I am using iometer (http://www.iometer.org/) to test the IOPS from one of t=
he vm.
As for IOPS is more trying to test the performance of block, rather than re=
al file transfer.
In my environment, I am using 10Gbe to make two gluster nodes be replicated=
. And I mount it to vm as a volume. I tested the performance both for SAS a=
nd SSD.
This is my current result with iometer.

The issue for GlusterFS I found is
- It can not retain the nature of SSD and SAS, such as SAS is stro=
ng for sequential access. SSD is strong for random access.
- In some case, especially for SSD, the performance is pretty bad.
Thanks,
Cong

Do you have any metrics to give an idea of the difference. I am using NFS r=
ight now, and I am migrating to Gluster. I have the gluster system up, and =
I see that it seems to provision disks faster than my NFS. I haven't used a=
ny real measurement tools to get actual metrics, this is all perceived.
Do you have an operational gluster?
Do what are you using right now?

[ovirt-users] Performance issue for GlusterFS as the block storage=
for VMs
Hi
I have one question about whether GlusterFS is the suitable solution to be =
used as the block storage for VMs.
The failure tolerant and scalability is good for GlusterFS, but in my test,=
it seems the iops is pretty bad. In some blog, it said, it is even with wo=
rse performance than normal NFS.
Should I use iscsi+drbd for the block storage for VMs.
Can somebody give some advice for this?
Thanks,
Cong
