They're faster than anything you've ever seen But I'm just a tease, apparently, and can't release any of my numbers due to confidentiality reasons, but have been playing with these for about a year now. I think it won't be long until some numbers are actually out there, though.I doubt anyone has these yet, but I'm eager to see some benchmarks too.
Just give it some time, someone will post something.
Those benchmarks are also limited by the fact that the Myricom interconnect is 10 gigabits, or 1.2 GB/s. I'd be surprised if PCI express were limited to half their theoretical capacity by another factor.
... yeah, start over again.stripe is 1mb..
array is 8 30 gb vertex raid 0
1. The raid card is a brand new product. All of the features listed on the box, may not be in the firmware yet.i have 8 30 GB vertex drives in raid 0...230mb/s each...x8=you do the math...something is holding me back here cant figure it out
Once overhead is taken into account, most of the things I have read say 1.6GB max for pcie 1.Those benchmarks are also limited by the fact that the Myricom interconnect is 10 gigabits, or 1.2 GB/s. I'd be surprised if PCI express were limited to half their theoretical capacity by another factor.
x4 PCI express 2.0 is 500 MB/s per lane, for a total of 2 GB/s. The card is also listed as 2.0 compliant, so it should work at at least that speed. Perhaps the partitions are unaligned to the SSDs at some layer?3. The manual for your board says "These four PCI Express x16/x8 slots are reserved for video cards, and x1/x4 devices". So maybe if the slot doesn't have a graphics card in it... it is knocked down to 4x pci-e 2.0?
First - depends on workload. For anything but single threaded video serving though, I can agree. Remember that multiple sequential streams are essentially a random workload.First, stripe should never be 1MB on a Windows host. Your real world performance blows.
Two, host filesystem should match segment size. 64k to 64k NTFS blocks, etc.
AreEss - I am going to have to seriously disagree with you here too. Myricom practically INVENTED high performance interconnect technology. Voltaire assembles nice switches, using Mellanox chipsets. Qlogic actually has a better IB switch technology IMO, and makes their own chipsets (since they acquired Silverstorm).Myricom is only just now starting to learn the basics of extreme high performance interconnect. If you want real numbers, you call one of two people - Voltaire, who makes the best InfiniBand switches on the market for edge-core architecture, or Qlogic, who's forgotten more about disk interfaces and high performance interconnect than any other company has ever known.
