This test emulates Database and On-Line Transaction Processing (OLTP) workloads. OLTP is the processing of transactions such as credit cards and high frequency trading in the financial sector. Databases are the bread and butter of many enterprise deployments. These demanding 8k random workloads with a 66 percent read and 33 percent write distribution bring even the best solutions down to earth.

 

The LSI loses slightly at 256 OIO with an average of 431,423 IOPS compared to 438,908 from the ASR-8885. While the 9361-8i loses slightly at the top end, the 9361-8i wins during the remainder of the test (8-128 OIO).

The Web Server profile is a read-only test with a wide range of file sizes. Web servers are responsible for generating content users 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 hosting the website.

 

The 9361-8i leads this test convincingly with a top speed of 354,078 IOPS at 256 OIO, while the ASR-8885 averages 309,421 IOPS.

The Email Server profile is a demanding 8k test with a 50/50 read/write distribution. This application is indicative of performance in heavy write workloads.

 

Once again, there is a near-tie at 256 OIO. The 9361-8i averages 439,322 at 256 OIO, and the ASR-885 squeaks past with 442,410 IOPS. The 9361-8i leads the lower 8-128 OIO in both performance and latency.
