Multi-Client Performance - CIFS on Windows

We put the Synology DS1815+ 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.

Synology DS1815+ Multi-Client CIFS Performance - 100% Sequential Reads

 

Synology DS1815+ Multi-Client CIFS Performance - Max Throughput - 50% Reads

 

Synology DS1815+ Multi-Client CIFS Performance - Random 8K - 70% Reads

 

Synology DS1815+ Multi-Client CIFS Performance - Real Life - 65% Reads

At the outset, it must be said that the two extra network ports on the DS1815+ (compared to the Seagate R8 and the DS1812+) make an apples-to-apples comparison difficult. In sequential workloads, the extra bandwidth delivers better throughput numbers. Average response times are also much better for the DS1815+. However, in the real-life and random 8K workloads, the performance of the DS1815+ and DS1812+ don't show much difference. The Seagate R8 also manages to deliver better results in a number of scenarios for this workload. That said, the average response times are excellent and the maximum response times are kept well under control.

    Sorry, that was meant as a response for JeffFlanagan's post above. :\

    Anyone have any idea when/if they'll put Rangeley in a 2bay unit? Not thrilled with the current 2 bay market.

    Synology doesn't have one (yet), but the Seagate NAS Pro 2-bay should fit your needs

    It is based on Rangeley too, albeit a 2C/2T model running at 1.7 GHz.

    Is there any specs on how these perform when compare to a simple, business-class server that has 8-bays? Something like a Dell PowerEdge T320 that has the capability for 8 x 3.5" drives and includes a quad-port GB NIC can be had for basically the same price as the Synology here.

    These larger-cost 8-bay NAS machines have a high price tag, so a natural competitor (in terms of price) seems to be servers from the standard server vendors. So I would love to see how it actually compares.

    Poorly. Their only advantages over a computer are smaller and more power efficient. People will talk about how it saves so much time but you have to save quite a lot of time to make up the difference in cost between a synology and a much cheaper and faster computer.

    I also would like to know if some of the poor network performance numbers shown by these selected NAS units are also present in a full server setup.

    I guess we'll never know because these review units likely come with caveats on what type of "competing" devices they can reviewed against.

    An Atom processor, 8 bays, 2GB of memory, and 8 bays, for $1050. I could build better for less, and get more flexibility.

    BUT YOU CAN SAVE SO MUCH TIME WITH A SYNOLOGY!!!!!

    Haha. Those peoples time must be worth a lot. And if it's worth that much, why are they going for a Synology and not something better?

    My time, plus any employees or services I have on the NAS could cost me the initial price each *hour* if it goes down. So having one physical unit, with hot swap, and on the fly rebuild is worth the price in some cases.
