What is SAN?



SAN -> Storage Area Network
Is a dedicated nework for sharing
resources.
Provides accelerated data access and
supports advanced shortage
management.
ภาพประกอบที่ 1.2 SAN คืออะไร
Problem:

The limitations loom over surge data


The rise of client networking, data-centric
computer applications and electronic
communication applications
Parallel SCSI bus is imposing severe limits
on network storage.
Problem:

Impending limitations of existing server
connectivity




Bandwidth to service clients and maintain data
availability
Scalability for long term, rapid grow
Flexibility to provide optimim balance of server
and storage capacity
Manageability for ease of installation and
maintainablity
The solution : SAN


Is a platform which interconnects
servers and storage at Gigabuad
speeds.
Combining LAN networking models with
core building blocks of server
performance and massstroage capacity.

SAN Architecture

The SAN
architecture
uses the Fibre
Channel (FC)
interface to
provide
flexibility that
allows the SAN
to do storage
networking.
What is Fibre Channel?

Fibre Channel is an industry-standard
interface adopted by the American National
Standards Institute (ANSI) and International
Organization for Standardization (ISO). Fibre
Channel transports data at 100 Mbytes (1
gigabit) per second. In addition, Fibre
Channel supports high-speed system and
network interconnects using a wide variety of
popular protocols, including TCP/IP, FDDI,
and ATM, as well as SCSI.

Topology



Point - To - Point
Fibre Channel Arbitrated Loop
Fibre Channel
Switching
Point - To - Point

topology consists
of a single
connection
between two
nodes. All the
bandwidth is
dedicated for
these two nodes.
Fibre Channel -Arbitrated Loop

In the loop topology,
the bandwidth is
shared between all
the nodes
connected to the
loop. The loop can
be wired node-tonode.This is
overcome by using
a Fibre Channel
hub. This Topology
resembles Token
Ring or FDDI
Fibre Channel Switching

A Fibre Channel
switching topology
uses either a single
Fibre Channel hub or
switch or multiple
interconnected
switches and hubs to
facilitate
communications
between nodes.
