Synology RS10613xs+: 10GbE 10-bay Rackmount NAS Review

Testbed Setup and Testing Methodology

Our rackmount NAS testbed uses the same infrastructure and methodology as the other units with a tower form factor. Performance evaluation is done under both single and multiple client scenarios. In the multiple client scenario, we run tests with all available network ports teamed with 802.3ad dynamic link aggregation. For these tests, we use the SMB / SOHO NAS testbed described earlier. This is the first 10 GbE-equipped NAS we have evaluated. Special mention must be made of the Netgear ProSafe GSM7352S-200 in our setup. It provided us with the necessary infrastructure to properly evaluate the capabilities of the Synology RS10613xs+.

Thank You!

We thank the following companies for helping us out with our NAS testbed:

• Thanks to Intel for the Xeon E5-2630L CPUs and the ESA I-340 quad port network adapters
• Thanks to Asus for the Z9PE-D8 WS dual LGA 2011 workstation motherboard
• Thanks to Dynatron for the R17 coolers
• Thanks to G.Skill for the RipjawsZ 64GB DDR3 DRAM kit
• Thanks to OCZ Technology for the two 128GB Vertex 4 SSDs, twelve 64GB Vertex 4 SSDs and the RevoDrive Hybrid
• Thanks to SilverStone for the Raven RV03 chassis and the 850W Strider Gold Evolution PSU
• Thanks to Netgear for the ProSafe GSM7352S-200 L3 48-port Gigabit Switch with 10 GbE capabilities.

Supermicro was gracious to loan us their mini rack (CSE-RACK14U). An interesting aspect of the mini rack is the fact that its height is that of the standard workplace desk (30.64"). This allowed us to use our existing NAS testbed (tower form factor) and power measurement unit easily along with the rackmount components (the NAS under test, the Netgear ProSafe switch etc.)

We have been using the Western Digital 4TB RE (WD4000FYYZ) disks as test hard drives for NAS reviews. As we saw in our previous reviews, RAID rebuilds take days to get done. With a large number of bays, usage of hard disks was going to be very cumbersome. In addition, hard disks just don't bring out the performance potential of the rackmount units. Therefore, evaluation of the Synology RS10613xs+ was done by setting up a RAID-5 volume with twelve OCZ Vector 4 120 GB SSDs. Tests were also done using Intel SSD 520 240 GB disks that were supplied by Synology along with the review unit. However, to keep benchmark results consistent across different NAS units, the results we present are those obtained using the OCZ Vector SSDs.

Thank You!

In order to evaluate single client performance, we booted up one VM in our testbed and ran Intel NASPT on the CIFS share in the NAS. iSCSI support evaluation was also done in a similar manner with a 250 GB iSCSI LUN mapped on the VM. For NFS, we ran IOMeter benchmarks in Linux. For evaluation of multiple client performance, we accessed a CIFS share from multiple VMs simultaneously using IOMeter and gathered data on how the performance changed with the number of clients / access pattern. Without further digression, let us move on to the performance numbers.
