RAID 0 Database/OLTP

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 four-drive array provides 712 IOPS, and the addition of more drives brings us up to 1,373 IOPS.

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 four-drive array averages 742 IOPS at 256 OIO, and boosts up to 1,434 IOPS with eight drives.

The email server workload is a demanding 8K test with a 50% read and 50% write distribution. This application is indicative of the performance in heavy write workloads.

 

Four drives in RAID 0 provide 689 IOPS, and that number rises up to 1,333 IOPS with eight drives.
