Performance: Network Storage Protocols in a KVM Environment

Our performance group has published a new white paper titled "Network Storage Protocols in a KVM Environment - NFS/SMB/iSCSI Report" (.pdf and .html).

Abstract: 

"iSCSI, NFS, and SMB protocols provide access to storage resources via a TCP/IP network. While iSCSI provides block device access, NFS and SMB are file-level access protocols. In cases where the devices are mounted on the KVM host (as in our case) they could be functionally considered as equivalent when utilized for KVM guest device attachment with image files."
