  • Hi

     

    I Have recently installed the "Disk Management" plugin from http://www.idolatry.org/uploads/WHSDiskMangement.msi

     

    Great plugin but it has highlighted the fact that the Home Server seems to be filling some of the disks up to 96% but hardly using the others (I have 6 disks - 3 internal and 3 external USB).

     

    Is this normal and/or should I be worried?

  • This is normal behavior for Windows Home Server. "Balancing" is a bit of a misnomer; it doesn't mean what one would normally think of as "load balancing" (spreading things out so that all drives have about the same amount of data on them) but rather that the second shadows of files are being created, certain consistency checks are run, etc.

  • There's quite a lot of smarts in Drive Extender that aren't really obvious at first glance (it likes to keep files from the same folder together, and provide space for the files to grow). My impression is also that DE values internal disks higher than external ones (USB) that could be disconnected much more easily.

     

    Have a read through the storage whitepaper: http://download.microsoft.com/download/2/F/C/2FC09C20-587F-4F16-AA33-C6C4C75FB3DD/Windows_Home_Server_Drive_Extender.pdf

  • No, you're probably getting pretty good throughput, assuming you're saying that you're getting about 5 megabytes (=50 megabits per second) per second on 100 megabit ethernet.

  • Will do guys - thanks for the advice.

     

    I have seen lots of posts around the (poor) performance of WHS - I am getting around 5mb/sec downloading between WHS and a VISTA laptop which are sitting next to each other connected via 100mb ethernet. This seems appalling even for PATA disks and an old 2.4gh pentium.

     

    Could the fact that I have 6 disks (I thought the more the merrier!) be causing performance problems and if so should I be dumping some of the smaller ones (I have the original 30gb internal and a 160gb USB)?

  • As Ken asks above, how are you measuring the speed and is the value bytes or bits per second? Also, is this read or write speed on WHS?

  • If you want speedier throughput I'd suggest moving over to gigabit ethernet. I'd say 5-7 megabytes per second is decent on a 100 megabit connection. I've never gotten much faster, though technically it should max out at around 12 megabytes per second.

  • Hmm - good question.

     

    I was just using standard windows Vista copy/paste which shows the download at around 5MB/s - which I assumed was megaBITS/sec - but looking at the timing/filesize must actually be megaBYTES/sec, which I guess is not that bad considerig that is about 40mbit/sec on a 100mb LAN.

     

    You can tell I come from a comms background! - Only think in mbit/sec.
