NAS product guide

NAS is so easy to install and manage that NAS sprawl is a common problem. This is why NAS is often a prime candidate for consolidation initiatives. Learn how to purchase NAS appliances with an eye toward NAS storage consolidation.

Network attached storage (NAS) gives organizations file-based storage flexibility. Since NAS is simple to install and configure, it's easy for storage administrators to add new NAS boxes when they need more storage. Unfortunately, that simplicity of installation often leads to a proliferation of NAS boxes that storage administrators cannot manage effectively. As a result, NAS is often a target for storage consolidation. The following cross-section of NAS appliances were selected based on input from industry analysts and SearchStorage.com editors. The specifications, which were provided by the vendors, are current as of January 2008. They are periodically upgraded. Vendors are welcome to submit their updates and new product specifications to Matt Perkins.
