I can't seem to find any good documentation on connecting a UCS system to iSCSI SAN storage. We run a Equallogic iSCSI SAN and I need to connect our UCS system to it. I can find plenty of documentation on Fibre Channel but obviously that doesn't help me. Does anyone know if any iSCSI configuration documentation that they can point me to? I just plan on using it for storage and will NOT be trying to boot from SAN.
There's no "formal" guide for iSCSI access, but it's pretty straight forward. It's just like setting up ethernet access to anything else. The only consideration you'd want to make is to your MTU size. Most people will configure Jumbo MTU/Frames on their iSCSI VLAN.
This requires the following to accomplish.
1. Creating a UCS QoS System Class with an MTU of 9000 & apply to the iSCSI vNIC(s) by Service Profile -> vNIC ->
2. Enable Jumbo Frames (MTU 9000) on all switches between Initiator (UCS) and iSCSI Target (Equalloqic).
3. Enable Jumbo Frames on OS Adapter (Vmkernel port for ESX, Network Adapter Advanced Properties on Windows)
As you can see the only UCS-specific task is the QoS policy which allows an MTU size of 9000 Bytes - assuming you're going to use jumbo frames in your environment - highly recommneded especially with 10G.
