Jumbo Frames on EMC Clarriion's iSCSI controller

We've recently purchased a EMC Clariion CX3 SAN, which we plan on implementing using iSCSI. After numerous amounts of research, I couldn't find any details on if the Clariion controllers supported larger MTU's / Jumbo Frames.

Well after EMC activated my PowerLink account, first thing I did.... Search for Jumbo Frames and I'm pleased to share the following knowledge:

Jumbo Frames are supported on the following devices (as long as you have Flare release 24 or higher installed):
  • CX3-10c
  • CX3-20c
  • CX3-40c
The bad news is, Jumbo Frames isn't supported on the older CX300i/CX500i or the AX series of arrays.
