Windows Server 2012 Storage Spaces Performance

I just wanted to give a quick update on the performance numbers we were able to get out of our clustered Windows Server 2012 Storage Spaces setup:


Here are the detailed results that compares the various hardware configurations (EMC CX3-40, LSI CacheCade, Storage Spaces) we have tested using SQLIO:

  1. Thank you for taking the time of sharing the results with us! Testing storage with SQLIO can be a challenging and time consuming process. I would recommend leveraging Crystal Disk Mark for quick and easy capacity and performance planning. Not as granular as SQLIO but definitely faster to get started with.

  2. The test results are fascinating. I’m really surprised at how well StorageSpaces performed compared to the Cachecade card. Can you tell me a little bit more, or maybe much more, on storage spaces setup with >= 10 drives?

    • The Storage Spaces setup is fairly straightforward. Here’s what we have on the hardware side:

      2 x Data On Storage DNS-1660D
      18 x Seagate Constellation ES.2 3TB SAS
      8 x STEC ZeusIOPS 400GB with 3.5 Caddy for DNS-1660

      2 x Dell R720 each with
      2 x Xeon 2670, 384GB RAM (mainly for Hyper-V)
      2 x Dell/Broadcom 57810 Dual Port 10Gb
      2 x LSI 9207 SAS HBA

      On the Storage Spaces side, the configuration is fairly simple. I’ve created a pool for spinning media and one for the SSDs. Each of the pools have hot-spares in each enclosure. I then created virtual disks that are enclosure aware which stripe data on a maximum number of disks possible. i.e. for the spinning media, the virtual disks are configured with 8 columns (disks) which are then mirrored between each enclosure.

      If you have additional questions let me know!
