Both of those machines have 8 RDIMMs and read as quad channel with the proper speed (1600MHz for my Dell and 1333MHz for the Supermicro).It's not critical, but your memory bandwidth looks low for dual E5s. Perhaps you don't have DIMMS in all of the memory channels?
Yes, for one disk.More importantly, was that 2,600MB/s for one RAM disk?
That's the first thing I tried in Iometer. Ctrl+clicked all 4 and got the same reduced 1780MB/s result as when I striped them.If so then that looks OK, so try spinning up three more RAM disks on the same machine: Just use the StarWind UI to "Add Device" three more times. Try four 4096MB RAM disks and set IOMeter to 8,000,000 sectors.
Don't RAID the RAM disks - test them as four separate disks in IOMeter. You can multi-select drives in IOMeter by control-clicking.
i'm just having the worst luck lately. The more money i spend, the more disappointed I get.
