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.

Hardware

  • 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. 1 piece of information is missing… what resiliency level was used for the Storage Space used in the performance tests?

  2. Yes correct. The performance test used Windows Server 2012 R2, Storage Spaces with 2-way mirroring.
