The exchange of data between servers and storage devices in a SAN takes place by using the fibre channel technology. The fiber channel technology is an American National Standard Institute (ANSI)-standard technology that is used for data transmission between servers and storage devices in a SAN. This technology enables the servers and storage devices in a SAN to communicate...
Implementing a SAN in an enterprise by using fiber channel technology provides various benefits, which are as follows: Improves data availability and speed of data access by providing multiple data paths between the servers and storage devices in an enterprise. Enables network administrators to perform fast backup and recovery operations. Fast data backup and recovery is possible because...
SANS provide the following features that enable the servers and storage devices in an enterprise to exchange data efficiently: High bandwidth: Enables servers and storage devices to exchange data at the speed of 100 MBps. This ensures that backup of data stored on servers can be taken at a high speed. Scalability: Enables network administrators of an enterprise to...
System Administrator The System Administrator (SA) is primarily responsible for the smooth operation of the System.It is a SA s job to switch on the system console.(The machine on which the Operating System resides , also known as the server machine.) The SA also creates users and groups of users for the system and tasks backup to prevent...
The ring topology connects the nodes on a network through a point to poinr connection. Consequently, no end points exist in this type of setup. The following figure shows a typical ring-based setup. In the preceding figure all computers are connected in a ring-like layout.As a result,similar to the bus topology, the main cable is the only transmission path.How...
The star topology connects nodes over a network using a central control unit called the Concentrater(Hub), Concentrater can be a Hub, a switch or a router. The hub is a device that transmits information from one node to another. The following figure shows a typical star topology setup In preceding figure , All computers are connected through a hub....
The bus topology connects all the nodes on a network to a main cable called bus, as shown in the following figure In the preceding figure Computers are connected through the bus, When a Computer needs to transmit data to an another computer , Is sends the data over the bus in the form of data packets. In the...
