What is a storage hypervisor? Are you already using one? A great post by Greg Schulz about storage hypervisors:
Storage virtualization (and storage hypervisor) considerations include:
- What are the various application requirements and needs?
- Will it be used for consolidation or facilitating IT resource management?
- What other technologies are in place or planned?
- What are the scaling (performance, capacity, availability) needs?
- Will the point of vendor lock-in be shifting or costs increasing?
- What are some alternative and applicable approaches?
- How will a solution scale with stability (performance, availability, capacity)?
- What is the management tools, along with plug-in and feeds for other tools?
- What are the hardware and software dependencies, service and support?
- Who is called and will answer the phone when something breaks?
- What APIs and interfaces are supported (VAAI, VASA, VADP, ODX, CDMI)
- Are any drivers or other software required on servers accessing the storage?
- What does the vendor interoperability certified tested support matrix look like?
