Benchmarks - Multi-Client Test
The Intel NAS Performance Tool (NASPT) is an excellent way to determine NAS performance in a single user environment. Any review that only uses NASPT assumes that only a single computer will access the target NAS at one time. We took issue with this method of testing and spent over a year designing, building, programming and finally validating the TweakTown Multi-Client Test.
The test uses Microsoft Office data recorded to traces and played back to the NAS from up to 120 client Windows 7 installations. We record total throughput and average response time per client.
Over time we'll populate the two multi-client charts with several NAS products from a span of categories ranging from a dual Xeon server with 2x 10GbE to a 2-bay NAS and then let the NAS being tested fall into its performance category.
Three to seven bay NAS are ran in RAID 5 and larger units over eight bays run in RAID 6.
The Infortrend EonNAS Pro 510 delivers higher throughput than the QNAP TS-669L, a six-bay NAS that uses the same Intel dual-core Atom running at 2.13GHz. Compression and dedupe are off in these tests. The EonNAS Pro 510 achieved peak throughput at 56 clients in our custom multi-client test.
At 56 clients the latency was still below 3ms at just 2.542ms. Here you can see the large separation between the TS-669L and the EonNAS Pro 510 in latency.
