Switch attach
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.
