Management server: HP Proliant ML350 G5 18GB RAM dual quad-core 2.0Ghz server SAN: HP Proliant ML350 G6 28GB RAM dual quad-core 2.66Ghz server running Open-e DSS v7 lite Virtual Hosts (2 identical servers) HP Proliant ML 350 G5 24GB RAM 2.66Ghz dual Quad-core with (4) gigabit nics Public, Guest, Storage, and Management networks are all assigned dedicated nics (cloudbr0-3)
Using NFS I'm getting 6-7Mbps write and 45-50Mbps read speeds with this setup. Using Microsoft software iSCSI from a Windows Vm running in this environment and attached to the same SAN, I get 13-14Mbps read/write speeds. (Access to the SAN traverses the virtual router. I'm not sure if this is affecting the speed or not.)
