Testing Fusion-io ioDrive – now with driver 3.1Vadim Tkachenko
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)
For random writes there is not much improvements, the throughput is about the same.
But there is a significant improvement for random reads. The results is stable on 640 MiB/sec level and it is higher than previously.
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).
