If you are out for availability, NFS isn't an answer, because the NFS server
remains a single point of failure. There are distributed filesystems
(Gluster, Lustre etc.) that can provide redundancy of storage nodes too or
you could have shared storage array with appropriate filesystem (GlobalFS,
OCFS2, etc.), but that requires special hardware. These will probably give
you better performance too -- git network protocol is optimized to send
minimal data, but that often means a lot more needs to be read from the disk.

I don't have personal experience with them though, so I can't give you more
specific recommendation.
