Comparing vSAS Performance to SATA

Customers have been requesting more aggressive SAS pricing for years, so once the value SAS solution had

been developed, Dell EMC contracted an independent third party to prove that vSAS SSDs provided notable

performance gains over the SATA SSDs. Three unique trials were exercised to evaluate performance

characteristics among different PowerEdge servers and application workloads. All tests concluded a significant

increase in performance per dollar, as shown below:

Figure 2: Test #1 had DVD Store 2 VMs performed on PowerEdge MX showing 49.6% latency reduction when using vSAS.

Figure 3: Test #2 had Benchmark Factory VMs performed on PowerEdge R740xd showing 71.6% more transactions per

second when using vSAS.

Figure 4: Test #3 had YCSB (Yahoo! Cloud Serving Benchmark) VMs performed on PowerEdge R840 showing 106.7% more

operations per second when using vSAS.
