3 big benefits of Storage Virtualisation

There are three main benefits of introducing storage virtualization:

1. Manageability increases the management capacity per administrator by streamlining management. It also reduces management work hours and facilitates the acquisition of management skills.

2. Scalability makes it easier to respond to requirements for added capacity and the like. It also enables a fast response to system performance requirements following rapid changes in demand.

3. Availability reduces downtime due to failures or configuration changes.

These points are similar to the benefits generally touted for IT infrastructure integration. For example, the above benefits may also be listed for the introduction of a SAN, which is storage network integration.

Virtualized storage operates on a more abstract level than SANs; in other words, hardware limitations have little effect on it. This could be said to improve convenience, but what does it mean for the user?

Since the connection environment has a large impact on the effectiveness of the solution for streamlining backups and disaster recovery, there is a large gap between DAS and SAN, but virtualization is not necessarily required.

But issues relating to ease of management (e.g., dealing with data growth, lack of administrators/reducing operating costs, and effectively using resources) are where the benefits of virtualized SAN over simple SAN come to the fore.

Although there are cases for performance concerns when migrating from a DAS to a SAN environment, most can be resolved by leveraging the flexibility gained through virtualization to dynamically hot-allocate caches, ports, and other resources to high-load applications.
