I can’t go into them in depth, but we exceeded the performance targets (the system was purposefully designed to do this). The gluster team rocks! (I can’t emphasize this enough)
Odd performance issue with the Mellanox QDR. Still trying to understand it, and hopefully will be able to update to our later kernel with the 1.5 OFED.
I can say that running 24 parallel independent writes to each RAID w/o any parallel file system in there gave us about 20GB of sustained bandwidth to disk in aggregate, for writes far larger than system cache. Same test with reads gave us about 24 GB/s.
This is a fast storage cluster. I can guarantee you will be hearing more about it soon.
