Figure 4. CPU Utilization
Storage Performance - I/Os per second (IOPS)
When measuring a storage system’s performance, Input/Output operations per second (IOPS) is
the most commonly used metric. The legacy environment achieved an average of 6,760 IOPS
while the PowerEdge R720 was able to achieve 11,110 IOPS: a 60% improvement. Figure 5
illustrates these results.
Figure 5. Input/Output Operations Per Second
Consolidation Improvement factor
After reviewing the results, we can conclude that a PowerEdge R720 server running Microsoft
SQL Server 2012 can process OLTP queries nearly
4x faster when compared to a legacy server
running Microsoft SQL Server 2005 while maintaining an SLA of 2 seconds.
