Hi.

Can someone explain in layman terms what is the meaning under the term "
shared block storage"? As far as I understand it's a shared storage device
(SAN, plain hard-disk, etc...), which provides write/read access to multiple
servers/clients, and coordinates all the access operations (i.e. locking
files, keeping files shadow copies, i.e.).

Also, can someone explain where actually the shared block storage appears in
Lustre? From what I read, the data is stored on separate storage nodes, and
not on shared disk.

Thanks.
