DataON Gets Over 1 Million IOPS using Storage Spaces With A 2U JBOD

I work for a European distributor of DataON storage. When Storage Spaces was released with WS2012, DataON was one of the two leading implementers, and to this day, despite the efforts of HP and Dell, I think DataON gives the best balance of:

  • Performance
  • Price
  • Stability
  • Up-to-date solutions

A few months ago, DataON sent us a document on some benchmark work that was done with their new 12 Gb SAS JBOD. Here are some of the details of the test and the results.


  • DNS-2640D (1 tray) with 24 x 2.5” disk slots
  • Servers with 2x E5-2660v3 CPUs, 32 GB RAM, 2 x LSI 9300-8e SAS adapters, and 2 x SSDs for the OS – They actually used the server blades from the CiB-9224, but this could have been a DL380 or a Dell R7x0
  • Windows Server 2012 R2, Build 9600
  • MPIO configured for Least Blocks (LB) policy
  • 24 x 400GB HGST 12G SSD

Storage Spaces

A single pool was created. Virtual disks were created as follows:


Test Results

IOMeter was run against the aggregate storage in a number of different scenarios. The results are below:


The headline number is 1.1 million 4K reads per second. But even if we stick to 8K, the JBOD was offering 700,000 reads or 300,000 writes.

I bet this test rig cost a fraction of what the equivalent performing SAN would!

        1. There is not to many JBODs with Backplane 12G. I have Supermicro JBOD for 45 disks connected to 12GB SAS LSI, but JBOD has onlu 6G πŸ™
          Anyway – I have connected storag servers with Hyper-V Cluster by Infiniband 56G RDMA and maximum recorded bandwitch was about 12Gbs πŸ™

          1. AFAIK, DataON is 12 Gbps end-to-end – they’re the one brand that has given a consistently good experience since WS2012. SuperMicro has a bad reputation in Storage Spaces in the circles that I communicate in.

          2. Aidan, maybe you have right, but there is no DataOn distributor in Poland. We have DELL, SuperMicro, HP, IBM… and nothing else.
            SM can work with many disks, so is cheaper than HP/DELL/IBM…

            Can you aim me on the right track with my storage? I have some small problems. By mail of course?
