Our NAS test 'system' has migrated to three 42U racks like what 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 X450e-48p switches and then to a Supermicro SSE-X3348TR top-of-rack switch. The device under test connects to the Supermicro switch via 1GbE, 10GbE, or 40GbE. The iSCSI and NASPT tests use a single machine connected to the Supermicro switch.
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 extend our thanks to AVADirect, Antec, Corsair, GIGABYTE, Icy Dock, Kingston, LSI, Noctua, Rosewill, Seagate, Thermaltake, 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.
Supermicro SSE-X3348TR 10GbE / 40GbE Switch
With a switching fabric of 1284 Gbps through forty-eight 10GbE ports with RJ45 connectors and four 40GbE QSFP connectors, the SSE-X3348TR is our switch oh choice for testing SMB and enterprise network attached storage products. Many server and motherboard manufacturers have included 10GbE on top-tier offerings. 2015 will be the year for a 10GbE take over.
