Guide to the state of NAS technology

Wherever an organisation needs access to file data, network-attached storage (NAS) systems will be present. Use cases range from the most mundane filer on the network at the smallest of small businesses up to enterprise-level "big data" repositories held in clusters of scale-out NAS devices linked by parallel file systems with capacity for billions of files.

In this guide we look at NAS technology and use cases, including NAS as virtual server storage, the pros and cons of scale-out vs non-clustered NAS, a survey of clustered NAS products in the market, NAS management challenges and a round-up of SMB-focused non-clustered NAS products.

The pros and cons of NAS as virtual server storage

In this interview, Bureau Chief Antony Adshead speaks with storage and virtualization expert Mike Laverick about when it makes sense to use NAS technology to support a server virtualization environment and how to divvy up management tasks between the virtualization platform and the LAN.

Scale-up vs scale-out NAS

The number of NAS technologies and products offered to combat data sprawl seem to be growing quickly. Storage managers are increasingly considering the differences between traditional scale-up choices and newer scale-out products. Read on for a quick overview of the evolving NAS market.

How scale-out NAS can meet the unstructured data problem

This article examines how scale-out NAS products from EMC Isilon and NetApp were updated last year and examine other companies that offer products in the scale-out NAS space, such as HDS/BlueArc, Avere, Panasas and Oracle.

Addressing NAS management headaches

NAS was a boon to organisations grappling with disk drives in multiple servers, providing many with their first taste of shared storage. But adding NAS units can bring NAS management headaches. In this podcast, site editor Sue Troy interviews bureau chief Antony Adshead about NAS sprawl, NAS management technologies and clustered NAS.

Traditional NAS for SMBs

The NAS market is a mature market but is also a rapidly changing one. A relative newcomer on the scene, clustered or scale-out NAS, has risen rapidly to meet IT organisations’ needs to store large amounts of file-based data. But, there is still a need for traditional NAS products to meet the needs of SMB NAS use cases such as small-business and departmental/branch office file serving.
