Concluding Remarks
The preceding two sections presented the results from the newly added test components using the new testbed. Standalone, they only tell a minor part of the story. In future reviews, we will plot results from multiple NAS units on a single graph (obviously, we won’t be putting the ARM/PowerPC based units against the Atom based ones) so as to get an idea of the efficiency and effectiveness of each NAS and its operating system.
Green computing was one of our main goals when building the testbed. The table below presents the power consumption numbers for the machine under various conditions.
| 2012 AnandTech NAS Testbed Power Consumption | |
| Idle | 118.9 W |
| 32GB RAM Disk + 12 VMs Idle | 122.3 W |
| IOMeter 100% Seq 100% Reads [ 12 VMs ] | 146.7 W |
| IOMeter 60% Random 65% Reads [ 12 VMs ] | 128 W |
| IOMeter 100% Seq 50% Reads [ 12 VMs ] | 142.8 W |
| IOMeter 100% Random 8K 70% Reads [ 12 VMs ] | 131.2 W |
Note that we were able to subject the NAS to access from twelve different clients running Windows for less than 13W per client. This sort of power efficiency is simply not attainable in a non-virtualized environment. We conclude the piece with a table summarizing the build.
| 2012 AnandTech NAS Testbed Configuration | |
| Motherboard | Asus Z9PE-D8 WS Dual LGA2011 SSI-EEB |
| CPU | 2 x Intel Xeon E5-2630L |
| Coolers | 2 x Dynatron R17 |
| Memory | G.Skill RipjawsZ F3-12800CL10Q2-64GBZL (8x8GB) CAS 10-10-10-30 |
| OS Drive | OCZ Technology Vertex 4 128GB |
| Secondary Drive | OCZ Technology Vertex 4 128GB |
| Other Drives | 12 x OCZ Technology Vertex 4 64GB (Offline in the Host OS) |
| Network Cards | 3 x Intel ESA I-340 Quad-GbE Port Network Adapter |
| Chassis | SilverStoneTek Raven RV03 |
| PSU | SilverStoneTek Strider Plus Gold Evoluion 850W |
| OS | Windows Server 2008 R2 |
Thank You!

Some of the biggest problems I have found in running my small business related to NAS's is file integrity under load. Is there a way to see if they have file integrity issues under load? Not just i/o or response times.Also, it would be interesting to see how their "feature set" holds up under load, as all of the NAS's purport to offer a variety of additional services other than purely file access/storage. Or is that only applicable to your lengthier reviews?
Lastly, most of these nas's don't have version tracking or something similar, so in a media setup, it would be interesting to see how they handle accessing the same file at the same time....can they serve it multiple times to multiple clients?

One last thought...it would be interesting to see free nas or some other DIY as an alternative.Peanutsrevenge - Wednesday, September 5, 2012 - link
Top marks!Bet it was satisfying when the SSH script was comlpete, just press this button and .....

How big a NAS can you test ? Does the server slow it down when testing 7+ virtual client load against NAS ? What is the client/host CPU usage, host system_cpu%, VM overhead ?Please test the server by running simultaneous tests to multiple NAS. Compare 6 clients alone to 1 NAS at a time with 2 sets of 6 clients to 2 NAS (or 3x4, 4x3). Is there any difference ? Is the test affected by the testbed CPU speed (try using a faster CPU eg. E5-2670) ? Can you test 16 or 24 clients (1 server) with 2 VM / SSD. Might need more RAM ? Now we are getting less SMB / SOHO and more enterprise :)

I got a bit of a chuckle out of G.Skill sending you non-ECC RAM.ganeshts - Thursday, September 6, 2012 - link
That is OK for our application :) We aren't running this workstation in a 'production' environment.bobbozzo - Thursday, September 6, 2012 - link
Curious, would ECC RAM use noticeably more power?extide - Thursday, September 6, 2012 - link
Why would they bother with ECC ram? Totally un-needed for this application..bsd228 - Monday, September 10, 2012 - link
ECC is absolutely needed for this application - Data integrity matters, not just data throughput.bobbozzo - Thursday, September 6, 2012 - link
Page 2, in the sentence"Out of the three processors, we decided to go ahead with the hexa-core Xeon E5-2630L"
The URL in the HREF has a space in it, and therefore doesn't work.
Thanks for the article!
