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 2-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.
Every system on the chart is a rackmount unit. We tested the Thecus N8900 in both 1GbE and 10GbE with an Intel X520-SR2. The Seagate Business Storage NAS outperformed the Thecus N8900 in the 1GbE test but lacks 10GbE capability.
On equal footing at 1GbE, the Seagate NAS shows where processing power and large DRAM comes into play and increases performance. In our 120-client test, we never reach a point where performance starts to drop back down. Over the holiday break we'll configure our new 400 client test and include the Seagate Business Storage NAS results in the Introduction to 400 editorial.
Compared to other units at 1GbE, the Seagate NAS has lower latency across the tests. We'll discuss the 10GbE option in the conclusion on the next page.
