I am having HP DL380 as well as backup disk appliance. Both are using the Intel X520 10GbE adapters and they are connected with the help of fiber. I performed a test with the help of a utility which generates a casual file on whatever purpose is specified, therefore it consumes source disk out of the equation. I am executing the test locally and I am able to see the local physical disk lying on the DL380 is able to write at around 400 MB/sec. While I ran it not in favor of SAN attached disk, I was equipped to write at about 500 MB/sec, that is the edge of the 4 Gbps fiber channel HBA's that we utilize. While I ran it next to the backup toward disk appliance through the 10 Gig Ethernet connections then it was just able to write at 330 MB/sec. The seller said that the disk subsystem is able to ingest over 1000 MB/sec, therefore I should be able to saturate the 10GbE NIC but I can't. I even attempted with the multiple streams of data. Anyone have any knowledge tuning/troubleshooting 10GbE performance?
