The operating system is based on CentOS 4.4, but is modified, and runs a proprietary file system. It has pretty good performance and I'm happy with it.

I would consider dumping the head nodes, and connecting the FC arrays 
directly to the host HBA, and running them as fiber JBOD to a dedicated 
host, which could run whatever sort of mdraid, lvm, file system you 
want.  or something like FreeNAS with ZFS and FreeBSD, then share stuff 
via SMB, NFS, etc.
