Multi-Client Performance - CIFS on Windows

We put the Asustor AS7008T through some IOMeter tests with a CIFS share being accessed from up to 25 VMs simultaneously. The following four graphs show the total available bandwidth and the average response time while being subject to different types of workloads through IOMeter. The tool also reports various other metrics of interest such as maximum response time, read and write IOPS, separate read and write bandwidth figures etc. Some of the interesting aspects from our IOMeter benchmarking run can be found here.

Asustor AS7008T Multi-Client CIFS Performance - 100% Sequential Reads

The Asustor AS7008T shows remarkable consistency in this test, with the network links getting saturated with as little as 4 clients compared to the 12+ clients needed for the Seagate R8. The DS1815+ wins in terms of the raw numbers because of the four native GbE links on the board.

Asustor AS7008T Multi-Client CIFS Performance - Max Throughput - 50% Reads

The 50% read workload presents a challenge to the AS7008T, though. Beyond 16 clients, we see a sharp decline in performance, something that the Synology DS1815+ doesn't suffer from. That said, the DS1812+ also demonstrated similar issues when it was evaluated last year.

Asustor AS7008T Multi-Client CIFS Performance - Random 8K - 70% Reads

In the Random 8K 70% reads workload, we find the Seagate R8 to be the surprise winner, but the AS7008T shows remarkable consistency.

Asustor AS7008T Multi-Client CIFS Performance - Real Life - 65% Reads

The observations we had for the previous workload hold true for the Real Life - 60% Random 65% Reads case too.

On the whole, the four network links in the DS1815+ give it the lead in terms of raw benchmar numbers for most workloads. Except for the 50% sequential reads workload, the AS7008T shows remarkable consistency when evaluated with accesses from up to 25 simultaneous clients.

    I'd love to have that rebuild speed in my Synology unit. But, you certainly do pay for that speed!

    Maybe I don't understand but what are you getting for your $1500 over building your own NAS with equivalent/better hardware?

    I understand the whole off-the-shelf and it just works aspect is worth a bit but $1500 seems extortionately high for what is essential just hot-swap bays on top of anything you could build yourself.

    I agree, I have my NAS, rackmount case (no hot swap sadly), and 5 2tb drives for a total of about $1000.00. (Drives were purchased at a slight premium to what they can be had for now).

    Here we go again. Not everyone wants to spend the time to research, build and install their own NAS. Having a single point of contact for support and software updates is also worth the $$ to some people and especially businesses.

    That being said, I do think the Asus is overpriced compared to a Synology, even taking into consideration the Haswell hardware.

    I don't disagree at all with that, there certainly is (as evidenced by the expanding options by various companies) a market for a one-stop, plug in the drives, connect the ethernet cable and power it up units. People are even willing to pay a premium for such a device in a space efficient package.

    However, any decent tech guy should be able to put together a decent simple Linux-based box (which is what FreeNAS is based off of) for file servicing. These days, with the hardware which is available, the bar to putting together something small, or large, power efficient, and rock solid is much lower and much less expensive than many people realize.

    FreeNAS is based off FreeBSD. Still Unix, not Linux though.
  • bill.rookard - Monday, December 1, 2014 - link

    Yes, I know it's based off of FreeBSD... technicalities... :) I guess I should have, since I was just using a basic generalization of the type of OS, that it was 'based of *nix' since they share very similar underpinnings.
  • Black Obsidian - Monday, December 1, 2014 - link

    I don't think anyone is disputing that SOME premium is justified by the value of a pre-built, supported machine. The question seems to revolve around how MUCH premium is justified, especially in larger NAS boxes like this one.

    Having recently built a media server with virtually identical specs, I can say that with Asustor you're paying a 200% markup for the convenience of pre-built and support. Which seems a bit steep, especially from Asustor, which doesn't have the brand cachet of Synology.
  • peterfares - Monday, December 1, 2014 - link

    Here we go again. People thinking these insane markups are justifiable.
  • peterfares - Monday, December 1, 2014 - link

    I'm sure it makes sense in SOME cases to buy these prebuilts but some people seem to really over-value their time.
