ISCSI Setup
I am working on a new setup where physical servers are going to be converted to virtual servers using VMware ESX 4.
What we have: 2 Dell R710 servers, 1 Dell PS4000 iSCSI SAN, 1 Dell PowerConnect 5424 switch.
Existing LAN: 192.168.0.0/23
New iSCSI LAN: 10.20.30.0/24
Question: Is this the best network design / IP scheme for this? Should the Dell 5424 switch IP be used as the gateway?
Attached is a diagram for you to view.
Thanks

The ESX hosts interfaces that are on the SAN subnet/vlan do not need interfaces.
The management interface needs a default gateway for heartbeat and communication

Looking at your diagram the red lines are your standard LAN, all of the addressing looks absolutely fine.
On the Equalogic you will have four interfaces (on each controller), and you have 10.20.30.1 as your group IP. I would drop 10.20.30.53, and use that interface on your 192.168.1 Network for management.
When you configure your ESX boxes, you will need to configure a VMKernel port group. Assign two NIC's to that port group which are patched into your 5424. As long as you give the VMKernel port group the IP of 10.20.30.54-57, it will not need a gateway as its all on the same network as the SAN.
You only need a gateway if you are connecting to anything on a different Network.

In addition to my previous post, any client on the 192.168.1 Network would not be able to ping any of the 10.20.30.* IP's - which is exactly what you want - a dedicated non routable network.
You will still be able to manage your Equalogic from your LAN

We already have plans on adding another 5424 in the next couple of months, they are not that expensive. I understand why not to use a gateway with 5424 but what about the SAN and ESX host, don't they need gateways?
