OCZ Vertex Turbo SSD that they used may not be the best choice for Zil.
It's not too bad, but according to benchmarks, it does lag behind
Intel's X25-M in IOPS:
If we believe the benchmarks, OCZ's SSD could provide ~900 IOPS during
fileserver benchmark. I assume that it would be in the ballpark of the
iozone tests in the paper. The number seems to correlate fairly well
with the paper's probes/sec graps on pages 12 and 13.
My bet would be that if they used Intel's SSDs (X25-M or, even better,
X25-E), they would probably see noticeable write performance bump.
