This test consists of 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 eight-drive RAID 0 array predictably takes the lead with 193,658 IOPS at 256 OIO, followed by the eight-drive RAID 10 with 120,116 IOPS. The four-drive RAID 0 delivers 111,787 IOPS, and the four-drive RAID 10 array weighs in with 62,613 IOPS.

The eight-drive RAID 0 array provides 180,000 IOPS under 2ms.

The Web Server workload is read-only 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 arrays top out at 128 OIO, and the eight-drive RAID 0 provides 112,457 IOPS at 256 OIO. The eight-drive RAID 10 isn't far behind with 113,375 IOPS, and the four-drive RAID 0 trails by a large margin with 76,802 IOPS. The four-drive RAID 10 tops out at 64 OIO with 65,207 IOPS.

Performance takes a step back as we move into heavier workloads.
