COMPONENTS
A Storage Area Network
(SAN) is a
specialized,
high-speed
network
that
provides network access to storage devices.
It
contains
hosts,
switches,
elements, and storage devices.
storage
It presents storage devices to a host such
that the storage appears to be locally
attached.
What is the use of SAN?

SAN components
 Improve application availability (e.g., multiple data paths)
 Enhance application performance (e.g., off-load storage
functions, segregate or zone networks, etc.)
 Increase storage utilization and effectiveness (e.g.,
consolidate storage resources, provide tiered storage, etc.),
and improve data protection and security.

The host layer represents the servers
that are attached to the SAN.
Fabric Layer
The fabric layer represents the cabling
and network devices that comprise the
network fabric that interconnects the
SAN hosts and SAN storage.
Storage Layer
The storage layer is comprised of the various
storage devices collected into various storage
pools, tiers or types.
