8K Randoms & Server Emulations
8K random read and write speed is a metric that is not tested for consumer use, but for enterprise environments this is an important aspect of performance. With several different workloads relying heavily upon 8K performance we include this as a standard with each evaluation. Many of our Server Emulations below will also test 8K performance with various mixed read/write workloads.
For 100% Random Read the 800GB version scores 104,700 IOPS at QD128 and the 400GB version tops out at 52,166 IOPS at QD128.
The 8K Random write speed in Steady State with the 800GB model tops out at QD64 with 23,995 IOPS and gets a boost up to 26,000 with extra Overprovisioning. The 400GB model scores 12,275 at QD32 in Steady State and with extra Overprovisioning scores 13,607 at QD32.
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 SSD is 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.
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.
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. This profile tests across a wide variety of different file sizes simultaneously, with an 80% read and 20% write distribution.
The Webserver profile is a read-only test with a wide range of file sizes. This test illustrates the performance of the storage solution with gamut of random reads.
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.
