Nas- not the artist!

Network attached storage is a solution which has a lot to offer not only to It works for users who do not have complex requirements because it is easy to use and manages and handles the smaller access workloads and speed for business operations in smaller companies. However, nowadays NAS storage has been widely developed and caters for the requirements of even most demanding clients.

NAS storage has the advantage of expanding its storage capacity using disk arrays such as RAID or clustering. In this way NAS products can provide a wide-range of network attachment capabilities to a broad range of host and client systems.

The new capability of NAS storage lets you maintain high performance with the increase of capacity and allows you to handle both small/random access and the large one, e.g. data from high performance computing applications. On the other hand, small file random input/output operations could include home directories, internet mail serving, web-based commerce, online transaction processing, securities trading, financial applications and general purpose file serving. As you can see, NAS storage provides scale-out capability for even very large storage infrastructures requiring high availability. It also offers tools for data protection, e.g. automatic replication serving for disaster recovery and business continuity.

Primarily, the first solution that resembled NAS storage was used to serve for a remote file access across a set of UNIX machines. With the development of technologies and protocols, NAS has evolved into a fully-fledged hardware and software products which are able to support many standard operating systems.

NAS storage is often contrasted with storage area network. They differ in terms of technology, capacity, target users and price. The two solutions for network storage however can be used simultaneously in the form of SAN-NAS hybrid. The hybrid system will support TCP/IP as well as fibre channel or iSCSI functionalities. In such environment it is possible for clients to have two types of access to the data: block as well as file level access.
