SMART Optimus 400GB Enterprise SSD Review - OLTP and Webserver

The SMART Optimus heralds the beginning of a new era for the datacenter, the inclusion of MLC NAND SSDs into roles typically only served via SLC high-endurance SSDs. Providing SLC-like endurance from MLC NAND sounds like a magic trick or marketing hype at its finest.

This test emulates Database and On-Line Transaction Processing (OLTP) workloads. OLTP is in essence the processing of transactions such as credit cards 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. 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.

 

At QD256 Optimus averages 36,837 IOPS, with fast IOPS reaching into the 42,000 range and the low end down to 25,000 IOPS.

There was a wide range of latency results at QD256, with 46% (5,213,758 I/O's) falling into the 4-6ms range. 18% (2,039,965 I/O's) fell into the 6-8ms range.

 

 

Webserver

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.

 

This read only test really highlights the agility of the SMART Optimus, averaging 28,468 IOPS in this demanding test. The highest recorded speed was 34,409 IOPS and the lowest was 25,500 IOPS at Q256.

66% (2,930,679 I/O's) fell into the 10-20ms range. 27% (1,214,919 I/O's) fell into the 20-40ms range.
