Hi John,
Redhat (equivalent to CentOS, sort of) is one of the HDF5 development
platforms.
You should be quite okay running HDF5 in Redhat on x86 hardware.
Parallel I/O is a different issue. It depends what parallel file
systems you use.
Two commercial systems, GPFS (by IBM) and Lustre (now owned by Oracle)
are possible options. Their performance varies and are highly
dependent on the characteristics of the I/O pattern of your applications.

I've recently been informed that we're going to be changing operating
systems and hardware architecture to redhat on an x86 blade system (or
something of the sort). I'm starting to investigate what all the
implications might be and am digging through the archives for items of
interest, but in the mean-time I was wondering if anyone out there was
using HDF5 on RedHat (no, I don't know which flavor, either, we
haven't been given much information), and what complications or
advantages they ran across in the process.
One thing of particular interest to me is the parallel I/O - I'd be
interested in hearing comments about that WRT RH. I'm not entirely
sure it's relevant to our system but it's worth researching anyway.
