Abysmal Performance on New CSV

Below might be solution


After some more testing with directly attached LUNs, I consulted this document again and I think I may have resolved my problems.
As recommended:
  • I have disabled autotune on the interfaces in my R710 with:
netsh int tcp set blobal autotuninglevel=disabled
  • On the switches I've re-enabled iSCSI optomizations, flow control, and Port Fast on all interfaces.
  • I've also renabled Jumbo Frame support on the Broadcom NICs, Switches, and SAN after disabling it for testing.
Before making the switch changes all three LUN types were performing horribly.
