NAS Vs. SAN – How To Build Your Network?

by Administrator 17. April 2017 17:39

Choosing the right storage solution for your company’s data can sometimes be a complex decision. It is important that you gain a deep insight into all the options available to determine the one that will be most suitable for your virtual environment. The technology will depend upon the following factors:

  • The type of data you want to store
  • Your budget
  • Usage pattern
  • Scaling concerns

Discussed below are the two main types of data storage, Network Attached Storage and Storage Area Network.

Network Attached Storage (NAS)

NAS involves the use of TCP/IP protocol, such as Ethernet, to connect to the network. An external device is attached to the web servers through a LAN or WAN. NAS devices usually run on a built-in operating system and management interface. Employees can easily access the files stored on the NAS just as they are on a local hard disc.

Benefits

  • Installation of NAS devices is very easy and does not require much time. In case you are in an urgent need for additional storage, NAS is your best option.
  • As file serving and storage is not handled by the web server, it reduces downtime to a great extent.
  • The NAS system is quite flexible and can work efficiently in organizations that work with different operating systems.
  • The low capital investment makes it a good choice for small to medium sized businesses.

Limitations

  • The scope of NAS devices is limited. They are only suitable for sharing files over the network.
  • The performance of NAS devices depends a lot on the network quality. Therefore, you need to get extended bandwidth while deploying a NAS solution.

Storage Area Network (SAN)

SAN is a more complex technology that connects to the network through a fiber channel or SCSI (Small Computer System Interface) protocol. The files are managed centrally and can be shared between multiple computer systems.

Benefits

  • SAN offers a high level of scalability. You can add as many storage drives you need to keep your data secure.
  • It is a suitable option if you require reliable storage solution to handle large volumes of data.
  • SAN system allows multiples users to access the files seamlessly, without any slowdown or downtime.

Limitations

  • The requirement of specialized equipment increases the upfront cost of installing a SAN system.
  • There is an increased risk of data corruption if several host machines connect to the same SAN device.
