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 HDDs perform very well at this mixed read/write workload, providing a tight range of performance. The 8-drive array averages 1,720 IOPS at QD256, the 5 drives average 1,162 IOPS and the 3 drives come in at 884 IOPS.
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 8-drive array averages just shy of 3,000 IOPS at QD256, the 5-drive array averages 2,144 IOPS and the 3-drive array averages 1,309 IOPS.
The Workstation profile emulates the usage patterns of a storage system on a typical user's workstation. This would be the closest to an actual operating system pattern that a user would experience on their desktop. This test is comprised of 8K random access with an 80% read and 20% write distribution.
The 8-drive array averages 2,049 IOPS at QD256, the 5-drive array averages 1,355 IOPS and the 3-drive array provides 980 IOPS.
