not disrespecting the gentleman from nssolutions, but anyone here have any firsthand experience with testing and results of a bluearc system? It would be very interesting to hear some first hand observations rather than 2nd hand anecdotal statements that "They all say it is the fastest machine they have ever tested."
When you spoke to etesting labs (I take it you meant etesting, not eweek) did you ask them what performance looks like for other kinds of real world scenarios other than 60 machines, each doing 12 simultaneous writes/and reads of 57K files? It seems to me that writing and reading only 57K files won't exercise disk I/O much. It would be interesting to hear how the BlueArc system does with multiple simultaneous reads and writes of 100MB files across those 60 systems. It would be exciting if they can sustain 200MB/s aggregate read/write doing that kind of workload.
Iometer Settings Number of Outstanding I/Os per target = 12 Transfer request size = 59 KB Percent Random/Sequential Distribution = 100% Random Distribution Percent Read/Write Distribution = 50/50 Read/Write Align I/Os on: 59 KB Run time = 5 minutes with a ramp up time of 30 seconds

I have spoken to several people that have one on demo. The all say it is the fastest machine they have ever tested. I spoke with eWeek about the numbers they were hired to do and they confirmed all tests were done without client side caching. There is no word on what features or functionality in is the software.

Anyone poke around with one of these things? Their wording soundsa bit sneaky ("2000 Mbps throughput" when they mean full-duplex Gigabit Ethernet, "inherent" 200 Mbps limitation in other NAS, 1700 Mbps throughput on FC, etc... huh?). Looks like they are still new to this game.
