What is Storage Area Network (SAN)

by Sudhir kumar


Storage Area Network a kind of There is a 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 called Shared-disk Also seen as File Systems.

storage area network Definition of

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.

Storage Area Network kya hai hindi

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 network Used to gain access to 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.

Automatic storage of SAN data as well as storing data In addition to monitoring the backup and storage, it also allows the 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.

  1. This improves the availability of the application.
  2. Increases the effectiveness of storage usage, strengthens storage resources, improves data protection even more.
  3. Storage area network plays an important role in the business continuity management of an organization.
  4. 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.

storage area network in hindi

Collective storage is connected to the server through a separate network. and Traditional Along with LAN, the 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 are called Storage access is required. 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.

SAN Fabric Topology Switch Types and Number of Switches such as Modular Or Edge Switch, The Backbone Switch also defines 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 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 of the traditional or solid-state drives, the time it takes to execute.

Advantages of SAN

here you Storage Area Network characteristics have been described.

  • data security Data security is important for every business. The security of data with SAN is excellent. It keeps your data safe. Your data is completely safe from hackers.
  • high availabilityThere is no failure path between the host and the storage device in a SAN. Communication across the fabric always finds an alternative path to maintain the availability of storage for workloads.
  • Reduce bandwidth problems – This Improves bandwidth problems.
  • fast data transfer speed – This technology transfers data through fiber optics, which can transfer data at a speed faster than 5 Gbps.
  • high performance – A typical SAN uses a separate network fabric. Fabric traditionally provides top performance for FC.

Disadvantages of SAN

as you above San Ke Fayde Well, in the same way, it also has some disadvantages.

  • expensive storage – A significant amount may have to be paid to use it, because this industry-Provides leading data storage and transfer facility.
  • Management – SAN Management is a kind of big challenge. Configuring Lun Mapping and Zoning is a problem for busy organizations.
  • improper operation on some servers – SAN does not work well on some servers.

What does Storage Area Network mean?

SAN is known as storing data. Which interconnect shared pools of storage devices for multiple types of servers.

How does SAN work?

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?

SAN The full form is “Storage Area Network”.
