[OmniOS-discuss] Fibre Channel performance on OmniOS

[Kyle Bruene]

Hi everyone,

Last year we built a "SAN" based on OmniOS r151008. Here are the specs:
2 x Xeon 6-core SNB
128GB DDR3 ECC
2 x 4 Port 4gbps Qlogic Fibre Channel cards
2 x 8 port 6gbps SAS controllers
2 x Brocade fibre switches.
5 x 1TB Crucial M550 SSD
5 x 3TB Seagate 7200rpm HDD

My issue is that I am only able to read/write to it at about 400-500MB/s sequential. There is plenty of cache so it seems like I should be able to get more speed with multipathing on. The hosts that are connecting to it are Windows Server 2012, but I've also tried an Ubuntu box with the same result. Is there anything I need to do on the OmniOS box to allow hosts to multipath to it? I've tried both Round Robin, Least Blocks, and Least Queue with no additional speed. It will use all the paths but will not go beyond that 500ish MBps limit. Does anyone have any insight into multipathing best practices?

Thanks.
