Cases meant to accommodate SSI EEB motherboards are few and far between. In addition to the motherboard size, we also had to make sure that the case could accommodate fourteen 2.5” SSDs. Our chassis of choice was the SilverStone Raven RV03.
We also used several SilverStone’s dual 2.5” to 3.5” adapters and 4-in-1 SATA power connectors to place the fourteen 2.5” SSDs in the various available 2.5” / 3.5” / 5.25” slots in the chassis.
Rounding up the hardware side of the build, we have the SilverStone Strider Gold Evolution 850W power supply. Its modular nature ensured that cable management was never a hassle (considering that we didn’t require any of the external PCIe power cables since the server adapters didn’t need them). The PSU fan has fluid dynamic bearings for low noise. The PSU's internal fan speed controller adjusts the fan speed depending on temperature and loading conditions. A fan filter with magnets is also included to prevent dust build up inside the PSU.
We now move on to the software side of things.

May I ask why do you guys need such high requirements? And why 12 VMs? I just think this is overkill. But it doesn't matter anyways... If I had a budget like this, I would totally build an awesome NAS like you guys have and follow this guide. Great job!xTRICKYxx - Wednesday, September 5, 2012 - link
I should clarify I am looking at this NAS as a household commodity, not something where 10+ computers will be heavily accessing it.mfed3 - Wednesday, September 5, 2012 - link
still didn't read...this is hopeless..extide - Thursday, September 6, 2012 - link
Dude they are NOT BUILDING A NAS!!!They are building a system to TEST other NAS's

It would also be nice to test against some of the other features like for example iSCSI. Also since the Thecus N4800 supports iSCSI, I would like to see that test redone with a slightly different build/deployment.Create a single LUN on iSCSI. then mount that LUN in the VM like ESXi, create some VM's 20GB per server should be enough for server 2K8R2 and test it that way.
I don't know who would use NAS over SAN in an enterprise shop, but some of the small guys who can't afford an enterprise storage solution (less than 25 clients) might want to know how effectively a small NAS, can handle VM's with advanced features like vMotion and fault tolerance. In fact if you try some of those HP ML110G7 (3 of them with a vmware essentials plus kit) you can get 12 CPU cores with 48GB RAM, with licensing for about 10K. This setup will give you a decent amount of reliability, and if the NAS can support data replication, you could get a small setup with enterprise features (even if not enterprise performance) for less than the lost of 1-tray of FC-SAN storage.

It's because they want to be able to really hammer the storage system.The0ne - Wednesday, September 5, 2012 - link
"The guest OS on each of the VMs is Windows 7 Ultimate x64. The intention of the build is to determine how the performance of the NAS under test degrades when multiple clients begin to access it. This degradation might be in terms of increased response time or decrease in available bandwidth."12 is a good size, if not too small for a medium size company.

12 is also a good size for a large workgroup.. Alternatively this is a good benchmark for students in dorms. sure there might be 4-5 people but when you factor in computers using torrents, game consoles streaming netflix along with tvs, could be interesting. granted all of this is streaming except for the torrents and their random i/o. However most torrent clients cache as much of the writes. With the current anandtech bench setup with VMs this can be replicated.DanNeely - Wednesday, September 5, 2012 - link
The same reason they need 8 threaded benchmark apps to fully test a Quad-HT CPU. They're testing NASes designed to have more than 2 or 3 clients attached at once; simulating a dozen of them puts the load on the nases up, although judging by the results shown by the Thecus N4800 they probably fell short of maxing it out.theprodigalrebel - Wednesday, September 5, 2012 - link
Well, this IS Anandtech and the article is filed under IT Computing... ;)
