SERVER PROFILES CONTINUED
Our last set of profiles include File Server and Web Server workloads. As mentioned before the last hour of preconditioning, the average IOPS, and average latency for each QD is graphed below.
The File Server profile is based on an 80% read/20% write mix. It’s made up of block sizes from 512 to 64K, each making up a different percentage of the access pattern. The pattern is: 512 bytes=10%, 1k=5%, 2k=5%, 4k=60%, 8k=2%, 16k=4%, 32k=4%, 64k=10%.
During the File Server benchmark we can see very similar performance to that of our Email Server results.
The Web Server profile is similar to the File Server profile, but has some additional 128K and 512K accesses thrown in for good measure. Additionally, the profile is 100% reads.
For the Web Server benchmark our preconditioning results are very interesting. IOPS range by about 20K lowest to highest and latency ranges 0.1ms. Performance gradually drops off over 2 minute intervals, but then quickly jumps up. Overall, it reached nearly 250K IOPS in RAID 0 at QD256 and latency is well controlled reaching the highest average of 1.03ms.
