Network Attached Storage or NAS refers to storage devices that allow users to connect to a network and provide file access services to computer systems. 

This type of setup generally has an engine that performs the file services and storage devices where you can store your data. Network Attached Storage uses file access protocols like NFS or CIFS.

NAS is a popular option with enterprise and small businesses across different industries. Why? Because it is effective, scalable, and affordable. This setup can be used for accounting databases, data logging, email systems, and many more.

What are NFS and CIFS?

Both Network File System (NFS) and Common Internet File System (CIFS) are protocols that are designed to allow a client system to access files stored on a remote computing device.

Network File System (NFS) 

NFS is used for giving remote access features to applications. Having remote access enables users to view and edit files from another computer within the network.

Common Intenet File System (CIFS)

This window-based network protocol is the public version of Server Message Block which was created by Microsoft. This protocol enables the devices to share multiple devices such as printers and multiple ports for both the user and administration. It allows huge companies to use data at multiple locations.

What is NAS Failover?

NAS failover

The name may sound scary, because who wants to fail? However, what does NAS Failover mean?

Two active-passive nodes make up the NAS (NFS) Failover. It could be a single cluster that is split across two locations. Once enabled, all data written to the primary server is mirrored to a backup server. Simply put,  this indicates that if the primary server (one of the two nodes listed) loses data, Open-E DSS V6 will automatically switch to the secondary server.

The process involves reassigning NFS locks to the secondary server after the primary server fails. So, the term should be a little less scary now. Although the idea of a server failing is scary-- you have nothing to fear if you have a backup strategy in place.

Why is a Failover Important?

NAS Failover Important

Since failover is the seamless process of automatically switching to a redundant system when the primary system fails-- you can bet that this process is important to your network.

No matter how amazing or secured you think your network is--- it can still be prone to a power outage, cyberattacks, natural calamities, or other issues. 

Failover makes sure that regardless of the type of malfunction in the primary system, the overarching system will continue to operate close to normal. 

Here are the biggest benefits that make deploying a proven failover solution important to any NAS or business network:

  • It ensures continuity of service. 
  • It minimizes downtime.
  • It lowers risks of lost productivity, lost revenue, and lost brand reputation.

Final Takeaway

NAS Failover is an essential part to achieve business continuity and seamless disaster recovery. Although it may sound intimidating, it is actually something that you need for your business network. It will help you keep on going in case your primary server malfunctions.
