Question : Problem: WTF's up with my iSCSI network config ???

Experts:

I just purchased an EMC AX4-5i dual-SP SAN appliance; two racks, one for SAS drives and the other with SATA drives. I'm just setting up the appliance and I'm stuck, hoping you all can help me figure something out.

If you look at the attached file you'll notice my vanilla setup: 1 server with 3 NICs connected to a pair of GigE switches configured in a meshed network connecting a pair of SP units, each with two iSCSI ports of their own.

The problem I'm having is that on the server i can only ping one of two switches and only two of four iSCSI ports

So before I go any further and start configuring iSCSI initiators or LUNs, etc...I wanted to clear up this networking mystery

Both are decent, The first one is more detailed on the clustering, the second one is more along the lines of how to fit clustering into your network enviroment. Both are a good read.

As for Web Related links, not sure what your looking for exactly, but here is a page from MS with tons of clustering links;

There's also a Step-by-Step Guide on this page.
