Testing a Synology DS1813+ Part# 4 – Performance testing

Last week it was at the time to send back my toy the Synology RS2414+ but I have still my DS1813+. So I go on testing.

The DS1813+ runs currently as my central iSCSI target and holds one SMB 2.0 share.

All LUNs and volumes are distributed over a disc group with four 1 TB Harddisk and 5.400/7.200 RPM (estimated 98/102 IOPS each).

Addionaly I configured SSD caching for iSCSI VM01 to increase performance. SSD Cache directly impacts memory usage of a Synology system. So I’m currently limited on 124GB SSD cache because I only have 2GB of memory.

Now to my testing scenario. I had a basic load on my DS with six running VMs, where the VM files and VHD are placed on the DS.

The basic load on my DS and Hyper-V host you can see in the screenshots.

Now I started two storage live migration from running VMs. Both consume together around 30GB of storage. The data is transfered from my local Hyper-V host with tiered storage space via 1GBit/s SAN network (converged network over three 1Gbit/s NICs and 1GBit/s bandwidth guaranteed). The DS has three 1GBit/s NICs as Bond connected to my SAN network.

In the screenshots you can see how the resource consumtion increases.

Conclusion: The DS1813+ is no complete enterprise system but for small/medium environments and testing purpose, the performance is more than great. I really enjoy that piece of toy.
