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 (clients). We record total throughput of all clients, 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. The products range from a dual Xeon server with 2x 10GbE to a two bay NAS with a single gigabit Ethernet connection. The products will fall into their performance categories based on performance, and not marketing material or opinion.
In the multiclient test, we see that RAID 50 and RAID 60 performance is very close in the Thecus N8900 with an Intel X520-SR2 10GbE card installed. RAID 50 takes a slight performance lead around 24 clients, but the performance is still very close.
