As the need for storage grows, companies are increasingly turning to virtual storage area solutions to meet their needs. These solutions use a technology generally known as virtualization to abstract and pool hardware resources to produce scalable storage area architectures that are definitely more flexible and easier to control than traditional hardware-based systems.

One type of virtual storage space is block-level virtualization, which consolidates a variety of physical hard disks to present these to applications as being a single logical device. This kind of overcomes the utmost size restrictions of specific devices not having necessitating that applications implement virtually any intelligence in their access.

Another form of virtual storage space is data-based, which roadmaps the characteristics of an emulated gadget — claim, a video tape drive — over a different physical device — such as a disc subsystem — and then signifies that towards the application. The server that stores or retrieves your data is aware of the mapping, but it really does not need to understand the details of the underlying machine.

Tip 1: When choosing a digital storage treatment, look for features that will lessen storage needs such as deduplication. This will reduce storage requirements, which will significantly lower the cost of storing info on a SAN.

When controlling virtual storage, be sure to consider the amount of bandwidth that will be necessary to transport the metadata that describes the virtualized storage units. This is a significant load that may cause performance issues about the host web servers, particularly if the storage units are oversubscribed. Also, be sure to plan for a sufficient number of hosts to support the complete capacity on the virtual storage area system.
