Hi,

We are in the process of setting up a virtual environment with iSCSI connectivity to local storage on the network.

My question is regarding best practice of the switch setup.  We have a HP ProCurve E2510-24G switch.  This will be used only for the NAS and servers to connect to for iSCSI.  Other than jumbo frames setting up on the switch and the VLAN settings, are there any other best pracitices to be used?

Many thanks

Specific Network Recommendations
• Implement a separate subnet or VLAN for the IP storage network for dedicated bandwidth.
• Set the individual Gigabit ports connected to the storage nodes and servers at 1000-full-duplex at both the switch and host/node port level.
• Implement switches with full-duplex non-blocking mesh back planes with sufficient port buffer cache (at least 512KB per port).
• Implement Flow Control on the storage network switch infrastructure.
• Connect an IP route from the IP storage network to the rest of the infrastructure so that the storage modules can be managed and alerts can be sent.
• (Optional) Implement Jumbo Frames support on the switch, storage nodes and all servers connected to the IP-SAN.
