This is how it is usually done using a SAN. Remember this not a NAS
which has built-in filesystem (NFS).

A SAN slice acts like a physical drive - you wouldn't wanna connect
one single HDD to multiple computer.

yup. You need something like NFS, AFS, GFS, Lustre, or DFS to allow
multiple machines to access the same storage.

May I ask why you want connect multiple machines to the same SAN
slice? Is it for clustering?
