Unity iscsi/windows/hyper-v

Question

Hi there, I am setting up Unity300 for the first time with iSCSI LUNS, connection from windows2016, which will be for hyper-v in subsequent steps Looking to check the setup, and find out any specific best practices/configurations for iscsi/win2k16/hyper-v Thanks. Here are the interfaces on Unity, on 192.168.10.x and on 192.168.11.x 10g/auto/jumbo (NO LACP) Here are the 2 NICS on the windows host, setup with windows mpio multipathing (not powerpath) First NIC on 192.168.10.x and Second NIC on 192.168.11.x Windows hosts registered in Unity, 4 paths connected

Please see KB 467477 - the iSCSI setup for hosts is the same for Unity as the VNX. Each host should have two interfaces (NIC), each on a separate subnet and there should be two subnets for the SP ports (your configuration is correct).

You should also disabled TCP Delayed ACK on each host (including and VM's). https://support.emc.com/kb/468345

You'll probably also want to review the following White Papers:
