Testing Fusion-io ioDrive

Following my series of posts on testing different SSD, in my last post I mentioned that SATA SSD performance is getting closer to PCIe cards. It really makes sense to test it under MySQL workload, but before getting to that, let me review the same workload on Fusion-io ioDrive PCIe card. This is yet previous generation of Fusion-io cards, but this is the one that has biggest installation base.

Driver information: Fusion-io driver version: 2.3.10 build 110; Firmware v5.0.7, rev 107053

Following the format of previous benchmarks, first is random write async 16KB case.

We can see some wave-like pattern with throughput 350-400 MiB/sec.

Random reads, async:

Interesting to see that there is quite unstable throughput in range 450-500 MiB/sec.
This is not usual for read-only workload to have such variety in throughput.

It gets even more interesting when we go to read sync IO, with 1-64 threads.

Response time:

For same cases (i.e. 4 threads) we see some interesting patterns.
As for response time, actually it does not seem much better than for Intel 520.
For 8 threads it is 0.6 ms ( for Intel 520 – 0.69 ms).

To better understand patterns in the read synchronous case, let me unfold results and show them in timeline (from 0 to 1800 sec):

I am not sure how to explain it, that with 4 and 8 threads the pattern is less stable than with 32 threads.

It is curios that I published results already for bunch of cards:

and each card shows individuals patterns and different handling of write and read IO cases.
