EqualLogic PS6100 MEM 1.5

Hi,

We are currently in the process of upgrading our VMware infrastructure from 5.5 to 6.5 with new physical hosts. We use a ps6100 SAN for storage. We are currently experiencing issues getting hold of the MEM 1.5 module as the unit is out of warranty. We do have support via a 3rd party, but they only provide hardware, not software.

We have made the following changes within the iSCSI setup

Changed policy for each volume to round robin

Changed login timeout to 60 seconds, Changed DelayedAck to disabled and changed NettcpipDefLROEnabled to 0

Are there any other settings that need to be changed. Also what are the drawbacks/ consequences of not installing the module (working on the assumption we are still having issues getting hold of it). Our current setup running VMware 5.5 uses the 1.3 module. Finally are we ok to install the module after the new upgrade goes live?

 

Thankyou for your help.

Kind regards,

Paul

Hello Paul, 

 Yes, in addition to Round Robin you want to set the IOs per path from 1000 to 3. 

  There are some other settings as well.   This Tech Report TR1091 covers those.
