The ultimate network-attached storage guide

NAS systems continue to evolve and maintain market relevance, particularly in the virtual storage sphere. This NAS guide takes a deep dive into network-attached storage architecture and the buying decisions that matter.

Introduction

When looking to simplify expanding network storage, network-attached storage (NAS) devices are a popular choice. Among its numerous benefits, NAS offers high scalability and dependable performance. We've gathered a wide range of expert content from our sites to create this network-attached storage guide that digs into the technology, explains where it works best and details purchasing considerations.

The use of NAS for virtual storage is showing increased adoption because the technology provides solid performance for companies with smaller budgets. But the never-ending need for more storage can lead to NAS sprawl. To combat this situation, data storage administrators can implement scale-out NAS, NAS management tools and file virtualization.

While NAS setup is simple by design, you need to ensure your deployment is easy and free of snags or setbacks. From the pros and cons of clustered NAS systems to architectural options, this guide to network-attached storage offers tips for smooth sailing.
