I have been playing with settings to get better performance with open-e and esxi4 using 10GB dual port cards using round robin. So I first changed the settings on the target and the esx host server too match the following settings:
I used iometer and was getting a combined Read/Write of 650MBs which was slower than the dual port 8GB fibre. I then decide to change the round robin iops setting in esx from the default of 1000 to 1 for the iscsi volume. I ran the same test and now am getting 879MBs. There is a lot of information about this in the vmware forums and certain vendors recommend changing this settings lower, i was just wondering if open-e has any information on this.
iSCSI Tuning found something interesting
