First, pre-tuning numbers for the *small* "velocibunny"

Ok, I know you have been asking … What is a “velocibunny” Think of it as … um … a very very fast JackRabbit. Not that JackRabbit isn’t fast … it appears to be best in its class in performance. But “velocibunny” is faster. A lot faster. How fast and what workloads?

It is specifically designed to be usable as a very fast database engine. As in PostgreSQL and related. Now mind you, it is in lab with the first iteration of an OS load, and ** NO TUNING** This is “build the RAID10 out of the box and start using it with a base load”. But, how fast is it? Random reads, 8k size across 128 GB of storage space (machine has 16 GB, RAID cards have much smaller cache … that is, these results are not cached) Using a simple fio script

[random]
rw=randread
size=8g
directory=/data
iodepth=768
ioengine=sync
direct=1
blocksize=8k
numjobs=16
nrfiles=1
group_reporting

We measure 38,582 IOPs. We do expect 46k or so after tuning. Also, we expect to be able to measure for the larger unit soon as well. Think ~90k IOPs if we have done our homework right.
