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. -- john r pierce 37N 122W somewhere on the middle of the left coast
