3.3. Scalability

Red Hat Storage is designed to scale for both performance and capacity. This implies that the system should be able to scale up (or down) along multiple dimensions. By aggregating the disk, CPU, and I/O resources of large numbers of commodity hardware — an enterprise should be able to create one very large and performant storage pool. If the enterprise wants to add more capacity to a scale-out system, they can do so by adding more disks. If the enterprise wants to gain performance, they can do so by deploying disks between more server nodes.
