Approaches for Managing Electronic Storage

As the necessity for storage area grows, companies are increasingly embracing virtual safe-keeping solutions to match their needs. These solutions use a technology referred to as virtualization to abstract and pool equipment resources to develop scalable storage area architectures that will be more flexible and easier to manage than traditional hardware-based systems.

One type of virtual storage area is block-level virtualization, which consolidates several physical hard disk drives to present these to applications as a single reasonable device. This overcomes the absolute maximum size limits of specific devices without requiring that applications implement virtually any intelligence in their access.

Another type of virtual storage space is data-based, which maps the characteristics of any emulated device — state, a tape drive — over a different physical device — such as a disc subsystem — and then symbolizes that for the application. The server that stores or perhaps retrieves the data is aware of the mapping, but it does not need to know the dimensions of the details of the underlying gadget.

Tip 1: When choosing a electronic storage solution, look for features that will reduce storage needs such as deduplication. This will minimize storage requirements, which can significantly lower the price of storing info on a SAN.

When taking care of virtual storage space, be sure to consider the amount of bandwidth that will be forced to transport the metadata that describes the virtualized storage gadgets. This is a large load which may cause efficiency issues on the host web servers, particularly if the storage equipment are oversubscribed. Also, be sure you plan for a sufficient number of hosts to support the total capacity of your virtual storage system.
