Essential guide to hybrid flash arrays

Last updated:January 2015

Editor's note

Hybrid flash arrays are the most common storage-side flash deployment today -- well ahead of all-flash arrays. Many users have added flash to existing storage to create a DIY hybrid SSD array. Plus, every major storage vendor offers hybrid flash arrays, and some sell a variety of them. Typically, an organization might have one or two applications -- such as a database or virtual desktop infrastructure (VDI) -- that require the performance flash offers. So, an all-flash array may be overkill.

Hybrid flash arrays offer the performance that organizations need for those critical apps, while keeping costs under control and boosting capacity with traditional hard drives. Of course, there are a number of important things to consider when choosing a hybrid SSD array. For example, should you build it yourself with existing storage or purchase a new array? If you opt to buy, has the vendor simply added flash to an existing array, or has the array been designed from the ground up or re-architected to take full advantage of flash?

This Essential Guide will look at the variety of hybrid flash arrays available today, offer info on typical hybrid array use cases, compare hybrid and all-flash arrays, and more. Readers will also learn common issues to watch for when deploying and managing hybrid flash arrays.
