Just configured a new DS to replace a Windows Storage server that is hosting CSV, configured the same MPIO settings as the old Windows NAS (Redundant nics and switches dedicated for iSCSi) but I'm seeing a big performance hit compared with the old windows NAS.
VM startup is awful, very slow and opening start menu in guest VM you can see a definite pause. When running on the old windows NAS VM's operated perfectly.
I'm using a Iscsi LUN block IO with multiple paths enabled (DSM indicates four initiator connections active). Anyone having performance problems with their DS? Any settings need adjusting?
I do notice that my MPIO setting on the new DS target is "Round Robin subset", whereas the windows NAS MPIO is set for "RoundRobin".
