Oh, I see.  Ok, I'll try to explain.  In lab benchmarks, using FIO, I have documented an average, per-node throughput for X410 of 1467 MB/s, using SMB2.  This was achieved by leveraging SMB Multi-channel on Win2012 clients and both 10G NICs on each Isilon node, using large block sequential reads.  Take that per-node throughput and multiple it by 144 (our current maximum cluster size), and you get 211241 MB/s, or roughly 200 GB/s.  This is what Marketing is doing to come up with that large number...
Hello, I couldn't find any documents that indicates how many X-Series nodes are required in a cluster to provide 200 gigabytes per second. Any info / refrence literature on this would be appreciated.  Saeid
