SDC compatibility

By design, the VxFlex OS SDC in this release is compatible with previously released VxFlex OS/ScaleIO systems (backend) that are currently supported (for example, ScaleIO v2.5 or VxFlex OS v2.6.1.1). In addition, the VxFlex OS system (backend) in this release is backward compatible with previously released SDC versions that are currently supported.

Some limitations may apply to mixed-version systems, such as:

  • Fine Granularity Storage Pool-based volumes cannot be mapped to a ScaleIO/VxFlex OS v2.x SDC
  • Snapshot Policy management is not available with SDC releases earlier than v3.0.
