Even if this was HA, it doesn't scale to HPC type needs. You end up with a single node bottleneck for all data you need. You also would have some sort of direct attached storage all connected to a single node.
Lustre/Gluster/Ceph/GFS and maybe HDFS (ideally with commercial MapR type NFS access) are probably the only viable options in the HPC use case.
If you have a lot of money to burn Isilon/NFS is an option as well.
