Steve’s NAS is full, he doesn’t want to manage two or more systems, so he is researching scale-out, unified storage that will grow with his business. But which systems really do scale both capacity and performance?
Legacy controller-based storage systems are designed with the ability to scale up capacity, but what about extra performance? Regardless of how much extra capacity is added, the performance is static, and the usability of VMs will only decrease as the controller is stressed, like adding more traffic to an overloaded freeway.
Scale Computing solves this problem by removing the controller bottleneck. A Scale storage cluster uses independent storage nodes, each contributing additional capacity to a single, unified storage pool, and each adding to the I/O bandwidth available. Collectively, the cluster delivers high-performance, redundant storage tailored for virtualization.
Many virtualization platforms support both shared block-level storage (SAN) and shared file-level storage (NAS). There are unique advantages to each, so don’t get trapped with only one option. Scale Computing storage clusters with ICOS use a Protocol Abstraction Layer to simultaneously offer iSCSI, CIFS, and NFS protocols with no extra licensing or gateway costs.
