The rise of scale-out network-attached storage

Last updated:December 2014

Editor's note

Scale-up or "traditional" NAS has a solid place in the data storage marketplace. It is relatively easy to deploy, provides quick file access and expandable storage capacity. However, in order to boost capacity, traditional NAS requires additional hardware, resulting in server sprawl that makes it hard to manage.

The market for scale-up is still strong, but in the hopes of increased flexibility, many organizations are turning to scale-out network-attached storage (NAS) for larger loads of data. Whether you're seeking to reduce sprawl when working with larger files -- such as video -- or avoid costly additions to your data center, scale-out is becoming a popular option.

With an increasing number of vendor offerings in the scale-out market and more large-scale organizations implementing scale-out NAS, it's time to examine what is out there and where it's all going. The links below provide insight into which products are currently on the market, how they measure up to alternate storage systems such as object storage, and what the future of scale-out in the storage landscape looks like.

1Benefits and drawbacks

Both object storage and scale-out NAS have proven to be more flexible than traditional NAS storage devices. The following links compare and contrast scale-out network-attached storage with other object-based storage and "traditional" or scale-up NAS.

2The future of scale-out storage

Wider implementation of scale-out storage promises big changes for the data center. Because scale-up is being eclipsed with varying approaches to NAS devices, the future of scale-out is looking fairly bright.
