Storage Area Network There is a type of computer network. Which provides a block level data facility to the users to maintain the storage. SAN A switch is a set of hosts, storage devices, and storage elements that make up it.
storage area network Only accesses the block level. SAN The file system that creates it provides file level access, also known as shared-disk file systems.

SAN is made up of hardware and software. Which is developed from data-centric mainframe architecture. Under which clients can stay connected to different types of servers in a network.
SAN We define it as an independent high-speed network that connects and delivers a shared pool of storage devices to different types of servers. All servers can access Shared Storage.
Storage area networks are mainly used to access data storage devices such as disk arrays and tape libraries. So that the device can show the operating system in the state of Direct-attached storage.
In addition to storing data, SAN allows automatic backup of data and monitoring of storage as well as backup process. SAN is a very dedicated network for storing data.
What is the use of SAN?
Storage Area Network Why is it used and what is its use.
- This improves the availability of the application.
- Increases the effectiveness of storage usage, strengthens storage resources, improves data protection even more.
- Storage area network plays an important role in the business continuity management of an organization.
- Improves the performance of the application.
How does SAN work?
It is a kind of network. Whose task is to keep the server connected to the storage. The function of a SAN is to receive and locate storage from different types of servers, centrally manage and protect storage resources.
Collective storage is connected to the server through a separate network. And along with Traditional Lan, Storage Traffic Performance is further optimized.
Storage Area Network Components or Components
SAN is known to have 3 different layers. Each layer has its own unique characteristics and components.
1. Host Layer
Host Layer represents Attach Servers. Host servers mostly run enterprise workloads such as databases, which require storage access. SAN Host also includes Separate Network Adapter which is dedicated to SAN Access.
Fc is the most popular and powerful technology among SAN technologies, the network adapters used for Fc SAN are called Host Bus Adapter (HBA).
2. Fabric Layer
Under Fabric Layer SAN Networking Device Live such as – SAN switches, protocol bridges, gateway devices, routers and cables. Compliant with Cabling and SAN Fabric Devices, Port Optical Fiber Connections employ cables based on Traditional Copper for multiple-distance network communication.
SAN Fabric When it is constructed, multiple connections are implemented to provide multiple paths. Any one of these paths Damage SAN Communication uses its Alternative Path.
3. Storage Layer
Storage layer is associated with different storage devices collected in different storage pools or tiers or types. The Storage Layer includes Traditional Magnetic HDDs (Traditional Magnetic HDDs). But it can also include optical media devices such as CDs, DVD drives and tape drives as well as SSDs.
About SAN Switches
SAN Switch The focal point of a SAN is with most network switches SAN Switch Receives data packets in a way. Also determines the source and location of the packet and forwards the packet to the device of the desired location.
The SAN Fabric Topology defines the types of switches and the number of switches such as Modular Or Edge Switch, Backbone Switch as well as the way the switches are interconnected.
Smaller SANs can use modular switches with 16, 24 or 32 ports, but larger SANs can use backbone switches with 64 or 128 ports.
Quality Of Service
SAN Storage The Quality of Service enables the calculation and maintenance of the desired storage performance for the customers. Some factors that affect SAN QOS.
1. Bandwidth – Measures the rate of throughput of the data that is available on the system.
2 . Latency – Checks for delay in time in read and write operations to execute.
3. Queue Depth – Underlying Disk helps in checking the number of outstanding operations for the time taken to execute traditional or solid-state drives.
Advantages of SAN
here you Storage Area Network characteristics have been described.
Disadvantages of SAN
as you above San Ke Fayde Well, in the same way, it also has some disadvantages.

It receives and locates storage from different types of servers.
How many components does a SAN have?
There are 3 components of this network which have been explained in detail above.
SAN What is full forum of?
