Asustor AS7008T 8-bay Intel Haswell SMB NAS Review
by Ganesh T S on November 30, 2014 5:05 PM ESTSingle Client Performance - CIFS & iSCSI on Windows
The single client CIFS and iSCSI performance of the Asustor AS7008T was evaluated on the Windows platforms using Intel NASPT and our standard robocopy benchmark. This was run from one of the virtual machines in our NAS testbed. All data for the robocopy benchmark on the client side was put in a RAM disk (created using OSFMount) to ensure that the client's storage system shortcomings wouldn't affect the benchmark results. It must be noted that all the shares / iSCSI LUNs are created in a RAID-5 volume. As expected, the more power platform in Haswell enables the unit to shine in almost all the single client workloads.
We created a 250 GB iSCSI LUN / target and mapped it on to a Windows VM in our testbed. The same NASPT benchmarks were run and the results are presented below. The observations we had in the CIFS subsection above hold true here too.
In a few of the benchmarks, the Rangeley-based Synology DS1815+ manages to take the lead over the AS7008T. This can be attributed to the fact that Synology's DSM is much more mature compared to Asustor's ADM.

I have a ZFS-based home-server that acts as NAS with also mail server, IMAP server (not to have mail on each client, less stuff to backup), and so on. I use a Xeon E3-1220 with 32 GB RAM and RAID10 (4x3TB).I used OmniOS (based on ilumos, a Solaris derivative) as operating system.
I would like to perform tests like the ones of this review to compare my home-built system with standard offerings (i know what I get with ZFS, I would like to know how much performances I lose), and also to compare the performances of a ZFS-based server with standard offerings that always use Linux mdadm (software RAID).
However with 32 GB (ECC) RAM (overkill, I know) doing reliable tests that are not affected by the (aggresive) ZFS caching is difficult.
Could anyone give me suggestions, or could Anandtech test a similar setup? after all, the product of this review is an i3 that may support (as some other i3 chips do) ECC, it would be a good choice for home-builds, whenever the desired fileystem is ZFS (OmniOS but also FreeNAs, or NAS4free).
Thanks.

Maybe they should test a HP Microserver running FreeNAS?As far as i can see, the Microserver series is by far the best when it comes to a cheap NAS build, if you want to run ZFS. The system with no drives costs 200 €, where you then must add 8 GB of ECC RAM, but you still get under 300 € for an ECC enabled ready made NAS case for 4 drives. Just a Xeon motherboard will cost you 140 € on the low end (for LGA-1150 CPUs, supporting ECC). With the Gen8 Microserver you even get the ability to swap out LGA-1150 CPUs. Gen7 uses AMD's offerings.

The Gen8 Microserver would make sense, but the Gen7 is too weak and is CPU limited. Concerning the other alternative you mention, keep in mind that Xeons are not the only option: if you can find a ECC-enabled mobo, y i3 with ECC support will do fine at a very low price. Check here for a configuration: https://forums.freenas.org/index.php?threads/ecc-v...Concerning FreeNAS (or NAS4free, they are both good): they may not achieve the full performances for ZFS-related tasks, compared to illumos kernels (like OmniOS or Nexenta), but it would still be interesting.

What does it need a 350W PSU for? None of the tests shown went above 135W. Even adding some margin for more power hungry drives and adding a bit of headroom to avoid efficiency/power quality penalties from running near full load it seems a 175 or 200W PSU would be more than sufficient.KAlmquist - Monday, December 1, 2014 - link
Some hard drives are specified to draw 2 amps on the 12 volt line when spinning up. Multiply 2 amps by 12 volts by 8 disks, and you have the disk drives alone drawing 192 watts while the system is powering up. In theory a user could install a 25 watt PCIe card and plug in USB devices that draw 18.5 watts. Add in power for the CPU and motherboard, and you are getting close to 300 watts.350 watts is overkill, but the cost difference between a 300 watt power supply and a 350 watt power supply is pretty minimal.

That's what staged/sequential powerup is for. Turn your HDDs and USB drives (if you support the higher power USB modes) sequentially instead of all at once. Higher end storage servers have done this for years; I'm not sure how far down the market it's gotten.hjones - Friday, December 19, 2014 - link
If you go to the Asustor website just from the model names alone it makes me think these are re-badged Synology equipment...at the very least they are OEMing some of the technology.The ADM config & management not only looks very similar, albeit differently themed...its even using the same underlying technology - Sencha ExtJS. The app store is remarkably similar too.
Anyone know more about this company? What is their relationship with Synology?

From Anandtech's own article (http://www.anandtech.com/show/7887/asustor-as304t-..."Asustor, Synology and Thecus were touted as partners building NAS units based on this platform"

I feel completely ripped off by Asustor. Avoid them at ALL costs. My 608T operated fine for about a month and then the network ports died. Won't take an IP manually or via DHCP. After two weeks of back and forth email (one per day since they respond at 3am) they finally provided an RMA. I sent it to them, they kept it two weeks and sent it back, supposedly with a new main board. It has the EXACT same issue. So incredibly unacceptable for a business class NAS to have such terrible, slow, and ineffective support. If you have an outage, expect ZERO sympathy from Asustor. They have no cross shipment capability and no advance replacement offering. I wish I had bought a Synology or built my own. This cost me 12TB of data.
