A Principled Technologies test report 6

Database performance and resiliency in the Intel processor-powered

Dell PowerEdge R630 running Microsoft SQL Server 2014

Figure 5: Application response

time comparison for the SSD

server configuration versus the

HDD server configuration, as

reported by the

rt_tot_avg_msec counter.

Lower numbers are better.

In addition, when we compared the costs and performance of the server

configurations against each other, we found that the hard drive-based R630 had a cost

per OPM of $0.45, versus the $0.13 per OPM of the SSD-based configuration, a 71

percent improvement. See Appendix D for further details on pricing.

CONCLUSION

We tested the OLTP performance of a 1U Dell PowerEdge R630, powered by

Intel Xeon E5-2660 v3 processors, running SQL Server 2014 in a two-node cluster that

was replicating the changes to the secondary node to show resiliency. While the server

delivered strong performance in its standard HDD configuration, this performance

improved dramatically when we tested the SSD configuration. Depending on the

number of databases in our configuration, the SSDs delivered from 7.7 times to 10.5

times as many total OPM as the HDD configuration with the same think time, with an

even level of service and reduced response times for users, while improving the cost-

per-transaction.

Companies will appreciate the 1U form factor of the Intel-powered Dell

PowerEdge R630, which lets it pack great performance into limited rack space. In

addition, when the Dell PowerEdge R630 is deployed as part of a cluster, its resiliency

features paired with Microsoft technologies enable a business to easily provide a safety

net for their critical data in a small form factor.
