This test emulates Database and On-Line Transaction Processing (OLTP) workloads. Used heavily in the financial sector, OLTP is in essence the processing of transactions such as credit cards. Enterprise SSDs are uniquely well suited for the financial sector with low latency and high random workload performance. Databases are the bread and butter of many enterprise deployments. These are demanding workloads with 8K random of 66% read and 33% write distribution that can bring even the highest performing solutions down to earth.

 

OLTP and Database data compresses very well, so the higher results will be indicative of the performance in deployment.

 

At QD 256 with incompressible data the WarpDrive averages 52,375 IOPS, with 80% compressible data it averages 61,612 IOPS, and for 100% compressible it averages 118,167 IOPS.

For incompressible data 32% of requests (73,746,667 I/Os) fell into the .6-.8ms range.

 

For 80% compressible data 64% of requests (24,017,791I/Os) fell into the 2-4ms range.

 

For 100% compressible data 59% of requests (41,727,091 I/Os) fell into the 1-2ms range.

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 speed of the webserver testing was remarkably consistent, with all types of data verging right below 100,000 IOPS at QD 256. This is a read-only test, and the WarpDrive performed admirably.

The Webserver results pegged all types of data performing in the same range, 2-4ms, for 86% of requests.
