iSCSI - Offload or Jumbo Frames
Posted on 2013-10-24
I have purchased a HP 530T card (1Gb), which is a hardware iSCSI card with TOE.
I planned to use the offload capability with jumbo frames but according to KB article 1007654
"You cannot use Jumbo Frames on a Broadcom card that is configured as a hardware initiator performing iSCSI Offload functions. You can either use Jumbo Frames or iSCSI Offload and you cannot use both together with the Broadcom adapters."
im not sure what config to go with
1) HP 530T Card HBA (switch off offload) and use jumbo frames
2) HP 530T Card HBA with offload but no jumbo frames.
Has anyone done any benchmark test with offload vs jumbo rames. Any advise on the route I should take?
Thanks in advanced
