A Storage Area Network (SAN) is a network of storage devices that can be accessed by multiple servers or computers, providing a shared pool of storage space. Each computer on the network can access storage on the SAN as though they were local disks connected directly to the computer.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.A SAN also employs a series of protocols enabling software to communicate or prepare data for storage. The most common protocol is the Fibre Channel Protocol (FCP), which maps SCSI commands over FC technology. The iSCSI SANs will employ an iSCSI protocol that maps SCSI commands over TCP/IP.
Why do you need a SAN : By storing data in centralized shared storage, SANs enable organizations to apply consistent methodologies and tools for security, data protection, and disaster recovery. A SAN is block-based storage, leveraging a high-speed architecture that connects servers to their logical disk units (LUNs).
Why use SAN storage
SANs increase availability and utilization
SANs off-load storage function to improve efficiency and isolate failures should they occur. Organizations also use a SAN to enhance business-critical application performance, making the applications more readily available and improving utilization rates.
Does SAN use SSD : Most SSD SAN Storage Arrays use a combination of HDD and SSD Drives, some even use Flash.
Both SAN and network-attached storage (NAS) are methods of managing storage centrally and sharing that storage with multiple hosts (servers). However, NAS is Ethernet-based, while SAN can use Ethernet and Fibre Channel. If your priority is easy file sharing and simplicity, NAS is a better choice. SAN is better for larger organizations using high-performance applications and requiring direct storage access. NAS is a more affordable option and is easier to implement, while SAN can be expensive and complicated.
What is SAN vs NAS
NAS is a single storage device that serves files over ethernet and is relatively inexpensive. NAS devices are easier for a home user or small business to set up. A SAN is a tightly coupled network of multiple devices that is more expensive and complex to set up and manage.Power outages can affect access to files, and a large amount of network bandwidth is needed to store large files. A constant internet connection is needed. Limited Scalability: NAS capacity is limited by type and number of drives they support. Large scale storage may require the purchase of several NAS systems.Cons and Challenges of Storage Area Networks
Initial implementation of SANs can be costly. They require expertise for setup and maintenance, adding to the complexity. Potential performance bottlenecks can arise from improper design or misconfiguration. NAS supports virtualized environments, but SANs are better suited to large-scale and/or high-performance deployments. The storage area network quickly transfers multiple I/O streams between VMs and the virtualization host, and high scalability enables dynamic processing.
What is the advantage that a SAN has over a NAS : In addition, while SAN focuses on high performance and low latency, NAS focuses on ease of use, manageability, scalability, and lower total cost of ownership (TCO). Unlike SAN, NAS storage controllers partition the storage and then own the file system.
Can SAN be used as NAS : NAS. Both SAN and network-attached storage (NAS) are methods of managing storage centrally and sharing that storage with multiple hosts (servers). However, NAS is Ethernet-based, while SAN can use Ethernet and Fibre Channel.
Who should use NAS
You should consider a NAS if you have more than one computer at home, since you can back them all up to the NAS rather than connect an external backup drive to each computer. If your priority is easy file sharing and simplicity, NAS is a better choice. SAN is better for larger organizations using high-performance applications and requiring direct storage access.

In addition, while SAN focuses on high performance and low latency, NAS focuses on ease of use, manageability, scalability, and lower total cost of ownership (TCO).
Why would it be bad for NAS to be used : Congestion and delays or interference with other traffic on the LAN can occur. NAS generally does not perform as well as SAN on a large scale, and higher traffic can cause latency.
