What is SAN for beginners?
In simple words SAN is a high-speed, dedicated network of servers and shared storage devices and provides access to consolidated, block level data storage. A SAN typically has its own network of storage devices that are generally not accessible through the local area network by other devices.
What is difference between NAS and SAN?
NAS is a single storage device that serves files over Ethernet and is relatively inexpensive and easy to set up, while a SAN is a tightly coupled network of multiple devices that is more expensive and complex to set up and manage.
What is a LUN in storage?
A logical unit number (LUN) is a unique identifier for designating an individual or collection of physical or virtual storage devices that execute input/output (I/O) commands with a host computer, as defined by the Small System Computer Interface (SCSI) standard.
How do you set up a SAN?
Connect every device of the pool with the switch using a fiber cable. Connect every server with a fiber switch using fiber cable. Attach a Host Bus Adapter card (HBA) on each server and pool to communicate. This is the easy set up of SAN.
Which is faster NAS or SAN?
SANs are the higher performers for environments that need high-speed traffic such as high transaction databases and ecommerce websites. NAS generally has lower throughput and higher latency because of its slower file system layer, but high-speed networks can make up for performance losses within NAS.
How do you connect a SAN?
What is the beginner’s guide to EMC?

What is a San and how does it work?
A SAN commonly utilizes Fibre Channel interconnects and connects a set of storage devices that are able to share data with one another. The administrator of a home or small business network can connect one NAS device to their local area network. The NAS maintains its own IP address comparable to computers and other TCP/IP devices.
