Well, let's go back a little bit in time. When all-flash storage arrays came out, a lot of them didn't have the features that are required of tier one, primary storage systems.
Early all-flash storage arrays were primarily used for acceleration. Typical use cases included database acceleration, virtual desktop environments and data stores for server virtualization. And the arrays were very effective, but they did not offer large capacities or many of the functions that IT administrators expect of primary storage systems. Today, the products have matured significantly. Many of them have such features as thin provisioning, snapshot and replication. Dedupe and compression are common as well.
So, today we're starting to see all-flash arrays in use as general-purpose primary storage. We have been watching how organizations are sizing all-flash array deployments. If an organization purchases a high-capacity, all-flash system, it is a good indication that the array is being used for more than accelerating a specific workload or application. These days, that is becoming more common.
