As the demands for more data consumption grow bigger because of the internet, storage area networks (SANs) become a fad. Adapting a SAN storage system is not as simple as you think it is. If you are looking for solutions that would cater to huge data storage and consumption without buying large servers, SAN might be it.

Why use a SAN?

If you want better disk utilization

If all your storage is tied together through a centralized storage network, SAN gives you the ability to manage it as one such as slicing up the resources to those that needs it most.

If you need a reliable DR (disaster recovery) solution

Critical servers normally have applications that can’t go down, these requires reliable recovery backups when disaster arises.

If you need better uptime for your applications

Simply, uptime boosts apps and business. Downtime spells tragedy. SAN provides data protection algorithms that make sure data stays consistent.

SANFaster backups

Backing up huge amounts of data is a major advantage in using SAN.

Why not to use a SAN?

Having the right staff, budget and business requirements would make sense in acquiring a SAN system however the following scenarios will tell you if it’s not a good choice.

If you have a few inexpensive servers

SAN is good only for several servers that will hook up on a storage network. You can see the benefits of a SAN when have a bunch of servers to hook up to the storage network. You need to justify the cost of SAN investment since it can be pricey.

If you want to save money

If you’re looking at ROI, you have to make sure that your business is growing fast otherwise you’ll end up spending more.

If you need a disaster recovery solution for a single application

A disaster recovery solution offered by SAN is only good for multiple applications and not for just single apps. As mentioned, this can be costly and adapting one may require a fast WAN connection.
