Hi Michael,
I noticed the code on the fio branch (that is where I grabbed the
spc1.[hc] files :-) ). Do you know why that branch has not being merged
to master?

Hi Justin & Luis,
We did a branch of fio that implemented this SPC-1 trace a few years ago. I can dig up the code and paper we wrote if it is useful?
Cheers, Mike

(Yeah, catching up on old unread email, as the wifi in this hotel is so
bad I can barely do anything else. 8-10 second ping times to

As a thought, would there be useful analysis/visualisation capabilities
if you stored the data into a time series database (eg InfluxDB) then
used Grafana (http://grafana.org) on it?

Hi guys,
I created a simple test program to visualize the I/O pattern of
NetApp’s open source spc-1 workload generator. SPC-1 is an enterprise
OLTP type workload created by the Storage Performance Council
(http://www.storageperformance.org/results). Some of the results are
published and available here:
http://www.storageperformance.org/results/benchmark_results_spc1_active .
NetApp created an open source version of this workload and described
it in their publication "A portable, open-source implementation of
the SPC-1 workload" (
http://www3.lrgl.uqam.ca/csdl/proceedings/iiswc/2005/9461/00/01526014.pdf
)
The code is available onGithub: https://github.com/lpabon/spc1 . All
it does at the moment is capture the pattern, no real IO is
generated. I will be working on a command line program to enable
usage on real block storage systems. I may either extend fio or
create a tool specifically tailored to the requirements needed to run
this workload.
On github, I have an example IO pattern for a simulation running 50
mil IOs using HRRW_V2. The simulation ran with an ASU1 (Data Store)
size of 45GB, ASU2 (User Store) size of 45GB, and ASU3 (Log) size of
10GB.
