We have had a pair of FS8600 installed with SCv2080 for the storage. This is presented on a 10Gb network for storage, we have been experiencing speed issues particularly with Read which are only ever between 85 - 105 MB/s which is slower than the old SAS storage that was being used and not much above 1Gb iSCSI.
I have a call open with Dell who so far are stumped on a solution, we have been looking at using Jumbo Frames to increase the speeds and after testing with Dell with and without Jumbo Frames i carried out some of my own testing and found that I can successfully Ping to and from switches and workstations using a Large frame size but the FS8600 controllers will not ping with Jumbo Frames max frame size is about 1476 bytes, the FS8600 is configured with Jumbo Frames and going through SSH the ports are all configured with a large frame size.
Anyone seen or have any ideas about this as it is really getting to the point where the speed is becoming an issue and is holding up the storage going in to full production.
