Follow Storage Area Network... 

--------

The research has been completed on the time and fulfills all the below objectives:

1- For the first objective which is snapshot and advantages of SAN has been given.

2- For the architectures of SAN: layer of SAN network with the figure has given an idea about SAN architectures.

3- For the techniques that SAN uses: Three techniques explained briefly, supported with figures for each techniques , although Fiber channel techniques consider as the best due to speed and data transfer of Fiber.

4- For topologies of SAN: four topologies mentioned and explained, supported with figures for each topologies.

5- For the recommendations,  the bellow points should be taken into consideration when SAN establish:

-          Appropriate cables for the wanted network and ensure that each cable must has the same data transfer speed, for the best cable is “Fiber Optic “.

-           Determine the network needed speed, so on that we can select the appropriate equipments.

-           Choose good quality hardware, switches for the most should be chosen carefully, often core switch such “Cisco Catalyst 4500E” is needed for high speed network.
