Test Procedure
In an effort to really stress the flash SSDs, we ran the following cycle on all drives:
1st cycle
- h2benchw sequential read/write test
- IOMeter fileserver, database, webserver, workstation profile I/O test
2nd cycle
- h2benchw sequential read/write test
- IOMeter fileserver, database, webserver, workstation profile I/O test
3rd cycle
- h2benchw sequential read/write test
- IOMeter fileserver, database, webserver, workstation profile I/O test
4th cycle
- h2benchw sequential read/write test
5th cycle
- h2benchw sequential read/write test
6th cycle
- h2benchw sequential read/write test
We decided to run the sequential h2benchw test and immediately switch to I/O loads three times in a row, so the drives would have to switch from maximum throughput to maximum I/O performance repeatedly. Then we ran three additional h2benchw tests to see if and when the flash SSDs returned to their initial performance levels.
