that is a good question, Fabrizio. The limit is the number
of luns many of these devices are limmited to. Some are
limited to presenting 16 LUNS (some as few as 4). Regardless of the
limit, the model is not suited to provisioning a large number of
servers.
Each LUN would have to be masked and access zoned. Also, there is
an issue with LUN to Port mapping internally. If you have an 8 port
device and wish to provision out, say, 16 LUNS for 16 servers, how
does that look ?
Contrast that to serving up NFS exports.
