In my previous post with results for Fusion-io ioDrive we saw some instability in results, I was pointed that it may be fixed in new drivers VSL 3.1.1. I am not sure if this driver is available for everyone – if you are interested, please contact your Fusion-io support representative. I installed new drivers and firmware, and in fact, the result improved.
Information about driver and firmware: Firmware v6.0.0, rev 107006. Fusion-io driver version: 3.1.1 build 172.
Actually an upgrade was not flawless, after a firmware upgrade I had to perform low-level formatting, which erase all data. So if you want to do the same – make sure you copy your data.
So there are results for driver 3.1 (with comparison to previous driver 2.3)
Random writes:
For random writes there is not much improvements, the throughput is about the same.
Random reads:
But there is a significant improvement for random reads. The results is stable on 640 MiB/sec level and it is higher than previously.
Sync random reads per threads, throughput:
Response time:
Again, there is improvement in throughput, in both in quality and absolute value. For response time – in some cases, there is 2x improvement.
So it seems for Fusion-io ioDrive it is worth to consider upgrade to 3.1 Driver (remember to copy your data before).
