Connecting hosts

Connecting hosts: direct attach—four servers/one HBA per server/dual path

Connecting switch attach configurations

A switch attach solution—or SAN—places a switch between the servers and the controller enclosures

within the storage system.
Using switches, a SAN shares a storage system among multiple servers, reducing the number of storage

systems required for a particular environment. Using switches increases the number of servers that can be

connected to the storage system. A Ultra48 Series controller enclosure supports 64 hosts.
The diagrams that follow show the SAN by using labeled switches and by using a cloud symbol to denote

a SAN fabric.
