Web Server





We precondition the drive for 16,000 seconds, or 4.44 hours, receiving performance data every second. We plot this data to observe the test subject's descent into steady-state. We plot both IOPS and Latency. We plot IOPS (represented by blue scatter) in thousands and Latency (represented by orange scatter) in milliseconds. We observe steady-state is achieved at 4,000 seconds of preconditioning for a single drive; 3,000 seconds for a two-drive array. We do note a significant number of outlying IO's.






The Web Server workload is a pure random read test with a wide range of file sizes. Our test consists of the following file sizes and corresponding percentage of the overall 100 percent workload file size: 512B = 22 percent, 1KB = 15 percent, 2KB = 8 percent, 4KB = 23 percent, 8KB = 15 percent, 16KB = 2 percent, 32KB = 6 percent, 64KB = 7 percent, 128KB = 1 percent, and 512KB = 1 percent.


With a 100% random read workload, Intel's DC P3700 is handily outperformed by the Techman XC100E5C. Samsung's XS1715 delivers slightly better performance than the XC100E5C at queue depth's of up to 64. The XC100E5C just edges out the XS1715 at queue depths of 128-256. Intel's DC P3608 delivers excellent performance as expected with this 100% read workload. However, the DC P3608 is greatly eclipsed by our two-drive Techman array. At QD256, the XC100E5C array is delivering 98K more IOPS than Intel's DC P3608.


Conclusion (TL;DR): Techman's XC100E5C is a far better choice for this type of workload in comparison to Intel's DC P3700.
