SAN -> Storage Area Network Is a dedicated nework for sharing

resources. Provides accelerated data access

and supports advanced shortage management.

What is SAN?

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 archit

ecture uses the Fibre Channel ( Fibre Channel (

FC)FC) interface to provide flexibili

ty that allows t he SAN to do st

orage networking.

What is Fibre Channel? - Fibre Channel is an industry standard inte

rface adopted by the American National S tandards Institute (ANSI) and Internationa

l Organization for Standardization (ISO). Fi bre Channel transports data at 1 0 0 Mb ytes (1 gigabit) per second. In addition, F

topology consists of a single conne

- Fibre Channel Arbitrated Loop

In the loop topolog y, the bandwidth i

s shared between all the nodes conn

ected to the loop. The loop can be wi - -red node to node. This is overcome b
