This test emulates Database and On-Line Transaction Processing (OLTP) workloads. OLTP is in essence the processing of transactions such as credit cards and high frequency trading in the financial sector. Enterprise SSDs are uniquely well suited for the financial sector with their low latency and high random workload performance. Databases are the bread and butter of many enterprise deployments. These are demanding 8K random workloads with a 66% read and 33% write distribution that can bring even the highest performing solutions down to earth.
The Intel retains its clustered performance with the mixed read/write workload, while the Optimus does begin to show signs of increased variability under this type of workload. Numerous instances fall well below the Intel's range, even though the majority of the I/O is above the Intel performance. This type of workload is well suited to Intel's latency consistency approach.
The DC S3700 averages 33,546 IOPS in contrast to the 36,837 IOPS from the Optimus.
The Intel delivers 8% of I/Os (871,837) in the 4-6ms range, 64% of I/Os (6,607,063) in the 6-8ms range, and 24% (2,501,265) in the 8-10 range. The Intel provides better overall latency in this test, winning in the 10-20ms range with only 2.1% of commands occupying this space.
The Intel averages 3.56 Watts in contrast to the Optimus with 6.5 Watts. This gives the Intel 9,418 IOPS per Watt with this workload, and the Optimus 5,659 IOPS per Watt.
The Webserver profile is a read-only test with a wide range of file sizes. Web servers are responsible for generating content for users to view over the internet, much like the very page you are reading. The speed of the underlying storage system has a massive impact on the speed and responsiveness of the server that is hosting the websites, and thus the end user experience.
The Intel averages 33,546 IOPS at QD256, and the Optimus averages 36,837 IOPS. Both SSDs exhibit some variance, but taking into consideration the scale of the graph it is minimal. The Intel apparently abandons its Garbage Collection cadence during this test, while the Optimus again pulls ahead in overall speed.
Though the Optimus exhibited better overall speed the Intel managed to pull off better latency during the duration of the test. The DC S3700 gave 64% of I/Os (6,607,603) in the 6-8ms range, and 24% (2,501,265) in the 8-10ms range.
The Intel averages 2.24 Watts, and the Optimus averages 5.61 Watts. This gives the Intel an average of 10,600 IOPS per Watt in this test, and the Optimus 5,071 IOPS per Watt.
