The K2 array is comprised of K-blocks — building blocks that include Active-Active controllers, one or more drive shelves, and connectivity for scaling out. The K2 platform scales-out to two, three, and four K-block configurations.  Even when scaling out the cluster remains fully N-ways Active-Active.
