What is the UnityVSA?
The UnityVSA falls into the Virtual Storage Appliance category. Essentially it is the software intelligence that goes into storage arrays (replication, file and data services, virtual volumes, etc) bundled into a binary file. This software can then be run on any commodity hardware or on older repurposed storage arrays to significantly reduce your storage costs. The VSA has four different flavors- a free 4TB Community Edition and EMC Supported 10TB, 25TB, and 50TB Professional Editions.
While the VSA enables a variety of use cases, here are my top three favorites:
1. Remote offices and Branch Offices:
Majority of organizations today have Remote Offices and Branch Offices (ROBO) with local IT infrastructure. While most of these remote locations have local servers running local applications and workloads, there is a need to constantly replicate data between these and a central data center. Deploying a VSA at these remote locations can allow you do this and significantly lower hardware and maintenance costs, and simplify manageability. Furthermore you can either choose the UnityVSA or one of the Unity hardware arrays at these different locations depending on your workload and still continue to replicate data between these different platforms!
