    CS220 with direct iSCSI connections to two ESXi hosts?

    Ron Fisher Newbie

      I found out today that Nimble does not support direct connections for iSCSI networking between ESXi hosts and the array. We have a couple HP DL380G8 hosts and the CS220. It is currently setup and functional but won't allow a software upgrade due to network issues. I'm unable vmkping the discovery IP on the array from the hosts yet the existing LUN.

       

      Has anybody ever made a direct connect (no Ethernet switches in the middle) work or are we stuck with having to add the switches? It is a remote office with no IT people so a long trip may be required.

       

      Thanks for any insight

          Hi Ron,

           

          This isn't a supported configuration - virtual IP floats across controllers so in your case not all vmkernel ports are going to see the VIP - I've had this same issue trying to direct connect hosts using HPE Storevirtual VSA.

           

          When using iSCSI you will need at least a single switch. Fibre channel is the only way I've ever been able to direct attach storage to hosts but this was a different storage system with active/active controllers.

           

          To be honest if you are investing a pair of DL380s and a CS220 at a remote site a pair of low-cost GbE switches would be a minor cost :-). Alternatively you could pull the CS220 back to a larger site or datacentre and go with a hyper-converged architecture that could help to reduce the remote site footprint.

           

          Cheers,
