Multi-Client Performance - CIFS

We put the Asustor AS-304T 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. IOMeter 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 AS-304T 4-Bay Multi-Client CIFS Performance - 100% Sequential Reads

 

 

Asustor AS-304T 4-Bay Multi-Client CIFS Performance - Max Throughput - 50% Reads

 

 

Asustor AS-304T 4-Bay Multi-Client CIFS Performance - Random 8K - 70% Reads

 

 

Asustor AS-304T 4-Bay Multi-Client CIFS Performance - Real Life - 65% Reads

 

The other 4-bay NAS solutions that we have evaluated before all come with two GbE links. This allows for link aggregation, enabling them to perform well in multi-client scenarios. We find that the single network link of the AS-304T acts as a bottleneck. Beyond eight simultaneous CIFS connections, the performance even starts to suffer a bit for certain workloads. That said, the AS-304T does manage to hold its own when it comes to performance consistency in terms of average response times.

    Can you install Plex on this unit? Reply
  • ganeshts - Wednesday, March 26, 2014 - link

    Yes, available in App Central: http://www.asustor.com/apps/app_detail?id=142

    However, like most platforms, there is no hardware accelerated transcode using Plex

    Isn't the 1gig of memory hard on apps though? Couchpotato/sickbeard/SABzbd would be a bad idea even if its available since they run as a service. Or am I thinking this wrong., Reply

    The hardware specs on these Home/SOHO NAS units are rather anemic. I built my own a couple years ago based on an i3-2120, 8GB RAM, and NAS4free. Much better performance than any Atom-based NAS unit. Reply

    I used to agree with you, but I picked up a Synology DS214+ recently and realised that these days, if you just want to be able to saturate a gigabit link when shuffling files, and stream media (with the exception of hardware transcoding to non-PC devices, natch) then something like 'this' is a much, much easier path.

    Especially as I build/fix/generally look after servers and general IT stuff for a living - last thing I want to be doing when I get home is build *another* RAID array...

    It's getting to the stage where these devices are good enough for most of us - IE power users - and only edge cases (such as transcoded streaming) really need a dedicated, self-built server.

    Not arguing!

    What if the device decides to quit working and you're using RAID. You may not be able to recover your data by putting the drives in another server. Especially if the original NAS is using hardware RAID. Reply

    Well, you still need to have a backup. Reply

    Most of these COTS NAS units (Synology / QNAP / Asustor etc.) don't use hardware RAID. Just take off the drives, plug them into a PC, make images and mount them. Linux systems can auto-recognize these RAID volumes. If using Windows, use something like UFS Explorer to get your data off it. That is the reason I like software RAID more than hardware RAID. Reply

    I completely agree. I could really blow the doors off of a NAS custom build. But when I get home after a 12 hour day of Raid rebuilds, Backup restores and email issues, the last thin I want to do is build a boring little Linux storage box.
    My next NAS will eitehr be Synology or Qnap. Good balance of features, performance and most relevantly, a MATURE OS and firmware.
    Heck I may even throw performance out the window and pick up one of the hated DROBO NAS products. They aren't the fastest, and their 'beyondraid' is proprietary. But when I've used their products in professional environs they were easy to set up and worked. Albeit slooooowly.
    Besides, I've yet to meet a raid array level 5 or hhigher that can be migrated between devices without backing it up and restoring it to the "new" raid.

    Software RAID on Linux is portable between devices. Reply
