If using a file system for the file storage isn't mandatory then I would go with an rdbms such as Postgres with the file stored in a blob field of a table. If the systems are in the same location and can use a shared Filesystem then I would look into getting a netraid scsi card or something similar. The netraid cards have the very nice capability of all sitting on a single scsi bus along with the datastore device (a hard drive or hdd array). There's no replication that occurs because they are all using the same data source jointly.

I believe they are up-to-date now. My understanding is that there is some delay after a new kernel comes out, but it should not be more than a few days. But we have to remember that the whole CentOS project is based on voluntary work by both CentOS team members and the community.
