Hi,

I've found some posts with tips for some iscsi config tweaks in the older v6 Beta threads.

We're also using DSS as storage for a vSphere setup and I'd like to get the best possible performace so is it recommended to change the iscsi settings from the default values?
Another question is do I need to change the config on both sides? DSS and ESXi?


I've found the following values:

maxRecvDataSegmentLen=262144
MaxBurstLength=16776192
Maxxmitdatasegment=262144
maxoutstandingr2t=8
InitialR2T=No
ImmediateData=Yes

I've also found the an answer which says that changing the MaxBurstLength results in problems:
