IBM SAN Volume Controller (SVC)

Why IBM SAN Volume Controller?

Storage virtualization is the part of the IT infrastructure that buys back a decision you already made: arrays from different vendors, bought in different years, stop being separate islands with separate tools. The price is a new layer that everything now depends on — which is exactly what needs designing for failure.

Heterogeneous storage is a management nightmare. Each vendor has their own tools. Data migration requires downtime. Features differ between arrays. Single point of control is missing.

IBM SAN Volume Controller is a storage virtualization layer placed in front of arrays from different vendors. Heterogeneous management - one interface for all of them. Zero-downtime migration - data moves while applications keep running. Uniform features - snapshots and replication behave the same way regardless of what sits underneath.

FAQ

Which storage arrays are supported? 500+ arrays. IBM, Dell EMC, NetApp, HPE, Pure and others.

How does virtualization work? SVC sits between hosts and storage. Virtualizes LUNs.

Does migration require downtime? No. Non-disruptive data mobility between arrays.

What is the latency overhead? Minimal. Typically <100 μs additional.

Does it add a single point of failure? No. Clustered architecture. No SPOF.

How does licensing work? Capacity-based. Subscription available.

Does it support NVMe? Yes. NVMe-oF for front-end and back-end.

How does it integrate with cloud? IBM Cloud tiering. AWS/Azure integration.

What’s the difference vs FlashSystem? SVC = virtualization only. FlashSystem = array + virtualization.

What about support? IBM support. nFlo offers architecture design and heterogeneous integration.
