Hi, Related, you might want to read the following paper: S. Alam, H. El-Harake, K. Howard, N. Stringfellow, and F. Verzelloni. Parallel I/O and the Metadata Wall. In the 6th Parallel Data Storage Workshop. Seattle, WA. November 2011. http://www.pdsi-scidac.org/events/PDSW11/resources/papers/pdsw07-alam.pdf
The paper is about adding SSD into Lustre and GPFS configurations, but I think the take-away (that PFSes don't benefit from the addition of SSD to the degree that they might) is relevant to PVFS also.
