This test emulates Database and On-Line Transaction Processing (OLTP) workloads. OLTP is in essence the processing of transactions such as credit cards and is used heavily in the financial sector. 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 and their data access patterns are similar to OLTP. 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.
The dual 910s reach 668MB/s in Steady state at a QD of 128 and with extra OP that value is raised to 719MB/s. The 800GB model reaches 344MB/s at QD64 with regular Steady state and 359MB/s with OP. The 400GB model reaches 172MB/s in Steady state at QD64 and 178MB/s with OP.
This test emulates a typical Email Server with a 50% Read and 50% write distribution of 8K random files. These types of servers aren't typical applications that many would expect solid state storage to be integrated into. With the lowering price points of high endurance SSDs, acceleration for these types of servers is becoming a reality. An added bonus is that an enhanced amount of IOPS capability equates to a higher average CPU utilization of the server, maximizing the performance and TCO/ROI of the overall system.
The dual 910s provide 560MB/s in Steady state at QD128 and 620MB/s with Over-provisioning. The 800GB model scores 290MB/s at QD64 with normal Steady state and 305MB/s with extra OP. The 400GB model reaches 221MB/s at QD32 in Steady state and 155MB/s at QD32 with OP.
The File Server profile represents typical workloads that will be encountered in file servers. The inherently random nature of data access in file servers can gain considerable boosts in performance from SSDs and also benefit greatly from caching and tiering solutions. This profile tests across a wide variety of different file sizes simultaneously, with an 80% read and 20% write distribution.
Again we can observe great speeds with the dual 910s achieving 876MB/s in Steady state and 932MB/s with OP.
The Web server 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 dual 910s provide 1945MB/s with both Steady state and OP at QD128. The 800GB model scores 976MB/s at QD64 in Steady state and 995MB/s with OP. The 400GB model scores a similar 970MB/s in Steady state and 993MB/s with OP.
