2. 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 คืออะไร

3. 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.

4. 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

5. 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.

8. SAN Architecture Fibre Channel (FC) The SAN architecture uses the Fibre Channel (FC) interface to provide flexibility that allows the SAN to do storage networking.

9. 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.

10. Fibre Channel Layer Physical Layer : FC-0 defines physical media and transmission rates. These include cables and connectors, drivers, transmitters, and receivers. FC-1 defines encoding schemes. These are used to synchronize data for transmission. FC-2 defines the framing protocol and flow control. This protocol is self-configuring and supports point-to-point, arbitrated loop, and switched topologies.

11. Fibre Channel Layer Upper Layers : FC-3 defines common services for nodes. One defined service is multicast, to deliver one transmission to multiple destinations. FC-4 defines upper layer protocol mapping. Protocols such as FCP (SCSI), FICON, and IP can be mapped to the Fibre Channel transport service.

15. Topology Point - To - Point Fibre Channel - Arbitrated Loop Fibre Channel Switching

16. Point - To - Point topology consists of a single connection between two nodes. All the bandwidth is dedicated for these two nodes.

17. Fibre Channel -Arbitrated Loop Fibre Channel hub Token Ring or FDDI In the loop topology, the bandwidth is shared between all the nodes connected to the loop. The loop can be wired node-to- node.This is overcome by using a Fibre Channel hub. This Topology resembles Token Ring or FDDI

18. 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.
