Safe Harbor

This technology allows IT shops to scale their initial purchase by adding a virtually unlimited amount of NAS nodes down the line without having to replace the original infrastructure. That simple proposition is fueling a slew of new products and purchases in the data storage industry.

In this tutorial, you'll read why scale-out NAS continues to replace traditional NAS, and learn which questions to ask yourself and your vendor while researching scale-out technology. You'll also get a first-hand account of how UCLA employed scale-out NAS to tackle its rising data storage requirements.

Why many IT pros are praising scale-out network-attached storage systems

In this article, senior writer Carol Sliwa explains the advantages of clustered and scale-out NAS architecture over traditional scale-up NAS configurations. She details the transition of scale-out NAS from an architecture primarily used for high throughput and high bandwidth applications to one that's useful for the entire market. She also outlines what vendors like Dell, EMC, Hitachi Data Systems and NetApp are doing to make sure this technology is included in their next line of data storage products.

Vendor landscape overview guide to your next scale-out NAS infrastructure purchase

Understanding the latest NAS technology is a critical part of running an efficient IT shop. That’s why we’ve broken down the latest network-attached storage products into three main groups: traditional/scale-up NAS, scale-out NAS, and scale-up and scale-out NAS. We analyze the most recent offerings from storage vendors and give you an organized, comprehensive way to understand all the latest NAS options.

How Isilon scale-out network-attached storage keeps a digital media business rolling

Five years ago, Industrial Color Inc. purchased an Isilon scale-out NAS infrastructure to hold 25 TB of data. Today, the organization holds 250 TB on this same system. This transition from NetApp’s traditional NAS system to Isilon’s scale-out NAS is an excellent example of scale-out NAS purchasing gone right, and shows how the architecture can satisfy even the hungriest of data storage operations.

Why UCLA opted for a scale-out NAS approach to its big data storage problems

Four years ago, UCLA’s Institute for Digital Research and Education (IDRE) turned to network-attached storage to manage its increasing file data storage demands. Today, the IDRE is looking to scale to almost a petabyte of data in a two-headed approach toward scale-out network-attached storage. This case study provides a great example of how you, too, can stay ahead of your file data storage capacity needs by leveraging a scale-out NAS architecture.
