Netgear ReadyNAS 716 Review: 10GBase-T in a Desktop NASby Ganesh T S on January 1, 2014 3:00 PM EST
Testbed Setup and Testing Methodology
Evaluation of NAS performance under both single and multiple client scenarios is done using the SMB / SOHO NAS testbed we described earlier. Tower / desktop form factor NAS units are usually tested with Western Digital RE drives (WD4000FYYZ). However, the presence of 10-GbE on the ReadyNAS 716 meant that SSDs had to be used to bring out the maximum possible performance. Therefore, evaluation of the Netgear RN716X was done by setting up a RAID-5 volume with six OCZ Vector 4 120 GB SSDs.

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.
Our primary testbed switch, the GSM 7352S, doesn't support 10GBase-T. Its 10GbE ports are SFP+ needing copper direct attached cables. We could have gone in for SFP+ to 10GBase-T converters, but, keeping in mind the growing popularity of 10GBase-T, a dedicated 10GBase-T switch made more sense. Netgear came forward with the XS712T, a 12-port 10GBase-T switch. The unit also has two SFP+ copper ports to allow stacking / uplinking.
In our testbed, the SFP+ ports on both the GSM 7352S as well as the XS712T are link aggregated and connected to each other. The GSM 7352S acts as a DHCP server and provides an IP to the XS712T. The 10GBase-T ports of the NAS were also connected to the XS712T (which acts as a DHCP forwarder) and they obtained an IP address in the same subnet as the virtual machines connected to the ports of the GSM 7352S. For teaming purposes, link trap and STP mode were enabled. The mode was set to 802.3ad dynamic link aggregation and the hash mode was set to 'Src/Dest MAC, VLAN, EType,Incoming Port'.
