P4500 DSM with 554FLR Accelerated iSCSI
I'm using 554FLR 10Gb Cards for a Converged fabric Hyper-V 2012 setup with P4500 storage backend.
I'm using DCB with Accelerate iSCSI. I'm unclear on the MPIO side of things.
1. Should I be using the Emulex OneCommand Manager to present/connect the iSCSI volumes or should I be using the iSCSI iniator select the HBA's as the source adapters? Both work for me I'm just unclear on the best practise and the supported MPIO route.
2. What is the correct MPIO setup in this scenario? Should the HP DSM be installed if using HBA/Accelerated iSCSI? I can get it working so I can disable either path and stay connected, but it doesn't appear the DSM is actually making the connections. If I check the StoreVirtual CMC I only see initiated connections to 1 of the 3 StoreVirual nodes. Normally when you connect to the Cluster VIP you would see initiated connections to all the nodes. I only see 1 redirected connection to a single node.
HP's documentation on this is severly lacking. Their LeftHand products feel neglected.

Re: P4500 DSM with 554FLR Accelerated iSCSI
So now, the 554FLR connected to a 5920. Does anyone know if I can get 4 NIC's our of those card? I've tried changing the personality to NIC only through OneCommand but after a reboot it never changes. It just goes back to iSCSI persoanlity (2 Host NIC's + 2 iSCSI HBA's).

Re: P4500 DSM with 554FLR Accelerated iSCSI
I disagree about the lacking documentation... most of their stuff is very clearly laid out with good step by step directions anyone should be able to follow. "Severely lacking" is a bit harsh when you are trying to find documentation on a setup that is not part of their suggested best practices... that said, I"ve said many times that if some new features such as thin space reclamation or SMI-S aren't added soon or clearly put on a published roadmap, that these products will be dead in the water in a few years.

Re: P4500 DSM with 554FLR Accelerated iSCSI
I feel like their R&D department. I buy the stuff, waste all my time. Spends hours with their tech support to get through to someone with a clue, only to find out I was sold a bunk solution.
For instance, their Comware switches and Procruve switches don't have a compatible 10GbE DAC cable. One is compatible with one switch, one with the other.
I've opened a case with HP. So far just the typical 2hrs repeating what I've already done with their Tier 1.

Unfortunately, this forum is like HP support... pretty dead... so I would be amazed if someone here actually had your exact setup.
