NetApp Says Data Storage Future is SATA and Cache Cards

NetApp President and CEO Tom Georgens said that in NetApp’s view, there will be no tiering of storage in the future. Instead we will be using SATA drives for our data and cache cards. As reported on The Storage Architect, the CEO's comments preview a change to the NetApp architecture in which the PAM cards are used to improve write caching.

"Tiering today enables customers to match workload to the price of the underlying storage hardware. EMC and Compellent are most well known for introducing technologies that enable data to be moved at a granular level, making best use of SSD. No doubt the other major vendors will follow suit as they release the next generation of their products. Storage arrays that can move small blocks of data onto the most appropriate tier of storage will deliver the next wave of efficiency. After that we should expect the array to manage the underlying hardware automatically, while we specify policies that dictate the service we expect. Tiering isn’t going away any time soon."
