    Well write speeds is not AS important as I will be accessing the data more then writing. Is there any throughput speed charts posted some where?

    I like Win7 and flexraid for this because:

    - your array doesn't suddenly become unusable if you lose a drive
    - you can add drives with data already on them to the array, or remove them and rebuild the parity
    - you can have as many risk units (data drives) or protection units (parity drives) as you have drives.
    - your parity units or risk units don't have to be local. They can be internal drives, usb sticks, or even network shares. Your shitty old NAS can become part of your new array. Hell you could use a drive on every computer in the house for parity if you wanted to go nuts.

    It seems to me like many of the people attempting this aren't sysadmin types and are getting in over their heads. You don't want to be in over your head when (not if) things go pear-shaped.

    These are the correct terms, Inexpensive Disks being the original and the way I've always known it.

    i know that. however like i have pointed out. there is nothing inexpensive about multiterabyte SCSI arrays. so when i was teaching in TAFE i have always told the students not to refer to RAID as redundant array of inexpensive disks. as not all arrays are cheap to setup. independent disks is more like it. as physically the drives are independent.

    So either Seagate or WD greens are good to use in raid 1?

    Hi all, I just purchased one of these but seem to be having some issues with my setup.

    I seem to be getting really slow network transfer speeds on my server (about 5MB/s over gigabit network) - The setup

    openindiana oi_151a installed on the 250gb hdd
    4x 2TB samsung+hd204ui drives in zpool (datapool)
    napp-it to manage
    8gb Ram

    desktop running winxp with gigabit ethernet
    Readynas with gigabit ethernet
    brand new netgear 16port gigabit switch
    New cat 5e cabling for all the network

    Some internal write tests:

    WRITE
    dd if=/dev/zero of=/datapool/dd.tst bs=1024000 count=10000
    10000+0 records in
    10000+0 records out
    10240000000 bytes (10 GB) copied, 43.7487 s, 234 MB/s

    READ
    dd if=/datapool/dd.tst of=/dev/null bs=1024000
    10000+0 records in
    10000+0 records out
    10240000000 bytes (10 GB) copied, 28.479 s, 360 MB/s

    os Drive write:
    dd if=/dev/zero of=test/dd.tst bs=1024000 count=10000
    10000+0 records in
    10000+0 records out
    10240000000 bytes (10 GB) copied, 137.347 s, 74.6 MB/s

    os Drive READ:
    dd if=test/dd.tst of=/dev/null bs=1024000
    10000+0 records in
    10000+0 records out
    10240000000 bytes (10 GB) copied, 93.259 s, 110 MB/s

    The internal write speeds seem good? but the speed over the network is appauling! - it took me just over an hour to do a DD test with the 10gb file and speeds were only about 4.8MB/s to the desktop and about the same to readynas

    Transfers from the desktop to the readynas go well above that and all other transfers in the network work fine. i've narrowed the problem down to the network card on the microserver. I've tried running knoppix 6.0, latest ubuntu live cd and debian install with the same issue. Are there any bios setting i may have missed? or something firmware wise that could cause this issue? Any one else having this problem?

    The last double check before you went out and got an Intel PCIe NIC (like the rest of us) would be to fire up an iperf server on the microserver and hit it from the desktop. See if speeds only drop off with larger size transfers.

    Little more digging in the spec sheet would appear the increase in cost would be due to the pre-installed Small Business Essentials 2011...The upgraded N40L chip doesn't seem to have affected reseller pricing too much - the newer models are still floating around for the $260 mark.

    Hey duality

    any more progress with your openindiana oi_151a setup and curing the bad network performance ? this is the platform I'm looking at running with.

    have you had a chance to test the network subsystem with iperf /jperf ?
    did you add in another non-broadcom nic ?
