Storage Area Network
Presented by Chaowalit Thinakornsutibootra 43650084 Thanapat Kangkachit 43650126
SAN -> Storage Area Network Is a dedicated nework for sharing
resources. Provides accelerated data access
and supports advanced shortage management.
What is SAN?
ภาพประกอบที่�� 1.2 SAN คื�ออะไร
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
