Switch Attach
A switch attach solution—or SAN—places a switch between the servers and the RAID chassis 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.
