So been testing storage with Jetstress 2010 Beta and I am not 100% sure its a really valid test?
So I have tested a Clariion and had mixed results with most of the test failing with over 20ms average read latency, but the IOPs are between 4,000 and 6,000!
Now i have just finished a test using an MDS600 configure with JBOD and a 13 disk raid 5 set and that fails too! In the JBOD configuration I am getting an average IO of 561.5 for the 5 disks and 484.7 for the 13 disk RAID 5.
So if I use these numbers:
| Random | Sequence | disk | |
| 2,5″ 5.400 rpm SATA | 70 | 80 | 80 |
| 3,5″ 7.200 rpm SATA | 65 | 75 | 75 |
… the MDS600 using 1TB SATA drives is performing okay if not better than expected,but I running jetstress with the MDS600 and it failing with 20 threads I wonder if:
- Jetstress if the test I should be using to benchmark the storage
- I am not using the parameters for JetStress
- if the MDS JBOD is the way to go?
Anyone got any view or ideas or thoughts?
