New Study Shows Dell Blades Outperform Cisco UCS

A newly published study by Principled Technologies reports in tests that the Dell PowerEdge M1000e blade environment delivered up to 91.7% greater throughput while running a virtualized OLTP database workload compared to a similarly priced Cisco UCS 5108 blade environment.  In addition they found that the Dell environment delivered consistent scaling as blade servers were added versus the performance degradation observed in the Cisco environment.

The testing environment performed by Principled Technologies included a comparison of database performance in similarly priced solutions:

  • Dell PowerEdge M1000e with 8 x PowerEdge M630 blade servers each powered by Intel Xeon E5-2690 v3 CPUs plus redundant 16Gb Brocade M6505 16Gb Fibre I/O Switch Modules
  • Cisco UCS 5108 with 8 x UCS B200 M4 blade servers (same CPU)

Both blade environments used:

  • Dell Storage SC9000 Array Controller
  • 2 x Dell SC420 12Gb SAS Enclosures (all flash)
  • VMware vSphere 6
  • Silly Little Oracle Benchmark (SLOB) 2.2 OLTP database

Within the testing parameters, Principled Technologies found that the Dell PowerEdge M1000e blade environment delivered 250,000 IOPS – a 91.7% greater total than the Cisco UCS environment with no major performance degradation on any single VM.  They also found that throughout the duration of the test, the Dell PowerEdge M1000e blade server environment read and write response time increased only slight as the number of blade servers increased.  In comparison, the Cisco UCS blade environment response time increased dramatically as blade servers were added.

    Could the max IOPS difference coming from the SAN connectivity: 2x16Gbps FC on the Dell side vs 2x8Gbps FC on the Cisco (FI) side ?
