Our NAS test 'system' has migrated to a full 45u rack like you'd find in a datacenter. There are ten servers that attack the target NAS with 120 Hyper-V installations of Windows 7 64-bit, each with a dedicated gigabit Ethernet port. The systems feed to three Extreme Networks Summit 400-48 switches that link together via Extreme Network's proprietary link cable system. One switch has two 10GbE Xenpak adapters installed. When testing NAS products with 10GbE capability, the NAS connects to the switch via single or dual 10GbE, courtesy of an Intel X520-SR2 installed in the NAS.
This level of testing wouldn't be possible without the help and support from several companies, many of which have little to do with NAS products. We would like to thank AVADirect, Antec, Corsair, GIGABYTE, Icy Dock, Kingston, LSI, Noctua, Rosewill, and Western Digital for their much appreciated support.
The Intel NAS Performance Toolkit (NASPT) is a file system exerciser and analysis tool designed to enable direct measurement of home network attached storage (NAS) performance. Designed to emulate the behavior of an actual application, NASPT uses a set of real-world workload traces gathered from typical digital home applications. Traces of high definition video playback and recording, office productivity applications, video rendering/content creation, and more, provide a broad range of different application behaviors.
TweakTown Custom 120-Client Office Test
The TweakTown Custom 120-client Office Test uses 120 Windows 7 Hyper-V installations and custom software to stress each NAS with traces from Microsoft Office tasks. Both throughput (in Mbits per second) and latency (in milliseconds) are measured.
Seagate NAS HDD
TweakTown uses Seagate NAS hard drives for all of our NAS tests. You can read our full review of the Seagate NAS HDD here.
