Xen users - May 2009 - Re: looking for some data regarding successful Xen deployment

On a similar note to Joe''s email below, I am looking for metrics or
documents concerning disk I/O performances for Xen 3.3.x.

More specifically, what are the performance gains observed between FC SAN (Emc,
Hitachi, 3Par..), iSCSI, NFS, SATA, and SAS disk storage?

Are there any domU image layout and tune up recommended? 

Thank you,
Lionel.
