Multi-Client Performance - CIFS on Windows

We put the QNAP TS-853 Pro 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. Detailed listings of the IOMeter benchmark numbers (including IOPS and maximum response times) for each configuration are linked below:

QNAP TS-853 Pro - 4x 1G Multi-Client CIFS Performance - 100% Sequential Reads

 

QNAP TS-853 Pro - 4x 1G Multi-Client CIFS Performance - Max Throughput - 50% Reads

 

QNAP TS-853 Pro - 4x 1G Multi-Client CIFS Performance - Random 8K - 70% Reads

 

QNAP TS-853 Pro - 4x 1G Multi-Client CIFS Performance - Real Life - 65% Reads

The important aspect to note here is that the performance for the random workloads when the VMs are active are all over the place, following no particular pattern. This is due to the fact that the PC Mark 8 'Work' workload running in the background doesn't uniformly load the system resources. It is sufficient to observe that even moderately heavy word processing or similar task can pull down the NAS performance for certain types of workloads.

In the absence of active VMs, enabling link aggregation with all four ports allows maximum throughput numbers in the order of 400+ MBps for pure read workloads.

    just to add, as others stated its expensive for the "ram" upgrade. I took out the 2gb that came with it and install 8gb (2*4gb) much cheaper. a guy on the forums managed to get 16gb working (even though the intel chip says that it can't handle it)

    I'm using an Intel NUC as my Media Box - with MediaBrowser. It's fantastic (and tiny). The fan can get a bit loud if it's transcoding, but I have it behind a cabinet door, so I can't hear it. And anyway, 99% of the stuff I watch is direct played not transcoded, and it's very quiet when doing that.

    I am also not bullish on using a NAS as a HTPC, which is why I don't give too much importance to the HTPC / XBMC aspect. A NAS should fulfil its primary duties - serving files well, and doing real-time transcoding if necessary. Anything else is just gravy on the top. VM capabilities are appreciated - particularly if the VM works on data that is on the NAS itself. Other HTPC aspects - not so much - this is why I think Synology is not missing much by avoiding HDMI output on their NAS units.

    The thing all of these types of review seem to miss is support. Try logging a support call and see what kind of response you get. Synology might have a perceived 'win' in this review but their support, at least in the UK, is non-existent.

    I had a problem with my current (older version) 8 bay Qnap which was causing a streaming pause when I started to copy new data to it. The support guys were great. They spent quite a bit of time troubleshooting with me logged in using Teamviewer. They eventually supplied a firmware patch, which was eventually incorporated into an official firmware release.

    All of these devices are very expensive.. And all of them are almost the same..
    Read about Hard Drives on http://www.hddmag.com/

    I would like to add my vote for an article of NAS targeted to home users.
    It is nice to read about these articles, but a review of a $1000 NAS, disks excluded, is quite useless for almost everyone.
    The market offers a lot of solutions for home users and it is not really easy to understand which is the one that is the right one for price/performance/features and most of all, easy of use.
    For example you have never reviewed a single WD cloud solution(1, 2 or 4 disks) that are cheap and may be enough for most of the users if they only knew what these devices can and cannot do.
    Comparing them directly with QNAP/Synology/Buffalo more expensive solutions may be an indication if all those added features and setup+maintenance time are really worth what they cost.

    Thanks in advance

    I have a TS-853 Pro 8G; currently populated with eight 3TB HGST drives; 7 in RAID6, one hot spare. I got it to replace a power hungry server that was using a Adaptec 52445 controller with 20 drives. I also used the server as a VM host for testing so finding a NAS that supported a VM really helped me choose the QNAP.

    My old server could transfer around 200MB/s while the QNAP is at around 115 MB/s which is acceptable for my use case. The VM setup is decent, but transferring a VM from a Windows Server to the QNAP box is a PITA. Not QNAP's fault really, that's a windows proprietary issue with the VHD setup. So far, no issues running a VM. As far as I can tell, the board will support another 8 GB of memory, but QNAP doesn't support it. I haven't yet purchased more memory to test that though. It would help with the VM hosting. The VM station only supports 2 administrator accounts which can be trouble for SMBs.

    As a note, this review lists the 853 can only support 2 VM's at a time. That is incorrect. In July Virtualisation Station 1.1v2088 and later no longer have a hard limitation for the number of concurrent active VMs. As long as there is memory and CPU available, have at creating more VM's. That's why I want more than 8GB of memory.

    The only worry I really have with QNAP is that their support seems not-so-good. If you read though the forum it is filled with issue reports without response from QNAP. As a power user, I suppose that is alright, but for a SMB, especially one without an IT professional, that would worry me greatly. What happens if the box breaks and you need to swap the drives to a replacement box? What if there is a config issue you can't fix? Defiantly worrying. The forum has a few non-QNAP people that really know what they are doing though.

    Also, something I researched and tried out was QNAP's hook into amazon Glacier. QNAP really messed up the beta of Glacier support for Amazon, which is probably why it isn't available in their app system yet. It is not optomized at all for Glacier. My NAS has something like 1.7 million files on it. Uploading them to Glacer in the way the app does it would cost $340 just to upoad. The app doesn't warn the user that it isn't optmimized or that it will cost so much. Download is even worse at something like a grand because of the coding. They really need to understand how to work with 3rd party groups because other apps have similar issues.

    the NAS itself has been great for the core features though. A bit pricy but so far I am happy with it.
