    I've googled this and I get a bunch of confused bullshit.

    Someone give me a number, a range. The real deal.

    I'm hearing that 50MB/sec is reasonable for upper end servers on the same switch.

    I'm lucky if I hit 25% on a SMB file transfer (which isn't the best test of course...)

    Memory to memory, same switch, I'm hearing 110MB. This is with Linux.

    Here's another question: A commodity 2U server with 2 processors, 4 cores each and 8 drives. The filesystem is streamlined for fast streaming. 7200 RPM disks, each one can stream 70-80MB.

    Can a typical server hard drive controller handle getting the full 70-80MB/disk to all 8 cores, from all 8 drives, assuming the read is evenly distributed and in big fat stripes?

    Probably wouldn't be paying their premium, sir.

    Just an example, our AIX box with local SCSI drives routinely pushes 45Mbps to our backup server. Backup server is running fiber attached LTO4 drives, not that it matters. :noes:

    Not bad considering its copying from a RAID 5 setup on 7200 RPM drives to my laptop(7200 RPM)

    We run high end Cisco, and enterprise HP blade chassis.
    Server side, never see more than 400-500mb/s loaded on the wire.
    Network side, depends on your switch.

    If its important, get a industrial grade switch. We run Smartbits traffic gens to verify throughput, and good hardware should be able to deliver the goods. You could also tweak some knobs to make your server more network efficient.
