No. It's not. CentOS lacks a number of the clustering features
available to RHEL, which are burdened by non-open-source licenses or
patents. RHEL is also investing considerable money in development,
which is helpful to support, especially if you need bleeding edge
drivers (as someone just needed here for a new SAS controller), and
for which you'd have to hope Google has an answer or you find someone
like, well, *me* to bundle you a new version nad fix it for you.

CentOS is also much, much faster to update once the updates are
published, and to use OS image building tools like "mock", because of
the distributed source repository rather than the burdensome DRM
involved in the RHN registration tools. CentOS also publishes kernels
with NTFS and similar support that RHEL has been leery of.

And to cover your ass.
