Attached direct network storage helps solve the enormous challenge of managing huge amounts of mission-critical data that businesses collect everyday. Over the past decade, the world has seen gigantic increases in the amount of data storage driven by a burgeoning global economy, e-commerce, e-mail, and the digitization of media. Researchers estimate that there are now several million terabytes of information floating around on the Web, and it continues to grow exponentially with every online transaction.

Today's technology market offers two broad options for storing data: direct-attached storage and networked storage. Networked storage in turn consists of two sub-options; storage area network (SAN) and network-attached storage (NAS). Statistics show that more than one-third of storage sold is networked storage, and experts believe this will increase to two-thirds within a few years time.

What Is Direct-Attached Storage?

In it's simplest form, direct-attached storage consists of a disk drive attached directly to a server. Data is then able to be transferred using SCSI (Small Computer System Interface) commands, which is also the most common mode of communication between a computer and a hard drive. Learning how these systems work will allow you to choose which type of data backup solution will work best for your needs.

All applications work transparently with attached direct network storage. This type of data storage works well in environments where there are only a few computers. However, as soons as there are multiple computers and servers being used, a need for a different type of data protection solution becomes necessary.
