Fixed path is not an option, HA benefits from Round Robin since it can use both pathes for reading the data. Fixed path should be avoided because it slows down the failover.
By the way, I've seen a similar performance drop with non-equal jumbo frames on the SAN servers. Could you please check the values in both device properties, and HP network utility (if used)
Max, when I setup my servers the first thing I do is setup Jumbo frames, so I decided to double check my results. Seems like a gremlin might have changed my Jumbo Frame settings
Attached is the new benchmark results with Jumbo frames corrected on all NICS, however we are still experiencing the same results.
