This is a quick demonstration of EMC Scale IO - a distributed software storage stack. It runs on a series of hosts (commonly at scales of tens to thousands) and repurposes the internal storage in the host (SAS, SATA, SSD, PCIe Flash) as shared storage across the network.

In this sense, it's similar to other distributed storage stacks like VMware vSAN. vSAN has superior integration with vSphere, internal VM-object semantics. Conversely, ScaleIO can be used for a broad set of use cases (including physical, virtual multi-hypervisor - and a broad set of OSes)

In this demonstration a 50 node ScaleIO cluster has an additional 10 nodes added, and the capacity is rebalanced while IO is being actively served. Then, a single node is failed, and the rebuild occurs while IO continues to be served due to the distributed protection and caching mechanisms in ScaleIO. Cool!
