Are we talking about a single ssd or an array of them? VMs are usually large
continuous image files. SSDs are faster delivering many small files over large
continuous file.
I believe ovirt forces sync writes by default, but I'm not sure as I'm using
NFS. The best thing to do is figure out

Hi,
Thank you for your reply.
I'm sorry but I don't think so. This storage is fast, because it is a SSD based
storage, and I can read/write to it with fast performance.
I know, in virtual environment the I/O always slowest than on physical, but
here I have a very large difference.
Also, I use
Unless you're using a caching filesystem like zfs, then you're going to be
limited by how fast your storage back end can actually right to disk. Unless
you have a quite large storage back end, 10gbe is probably faster than your
disks can read and write.

Hi All,
I have to create a test environment for testing purposes, because we need to
testing our new 10gbe infrastructure.
One server that have a 10gbe nic - this is the vdsm host and ovirt portal.
One server that have a 10gbe nic - this is the storage.
