HP on software-defined storage: why VSA is the future
In my last post, I posed a question: How do you define software-defined storage? I offered up a base definition of what software-defined storage means to HP. Since then IDC has released a new taxonomy on software-defined storage which includes this definition:
IDC defines software-based storage as any storage software stack that can be installed on any commodity resources (x86 hardware, hypervisors, or cloud) and/or off-the-shelf computing hardware and used to offer a full suite of storage services and federation between the underlying persistent data placement resources to enable data mobility of its tenants between these resources.(1)
Our definitions are very similar: industry-standard hardware layered with feature-rich storage software.
If you think about it, software-defined doesn’t mean software-only. There’s no requirement that a hypervisor layer must be in the mix. It’s left open to allow the end-user to decide what’s best for their infrastructure. But focusing on the software, the biggest benefit the application brings to the environment is the increased utilization of the hardware infrastructure already in place with the addition of better efficiency all around.
