SDC compatibility

By design, the PowerFlex SDC in this release is compatible with previously released systems that are currently supported (for example, VxFlex OS v3.0.1). In addition, the PowerFlex 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:

  • Replication is not supported on SDC releases earlier than PowerFlex v3.5.
  • The CHAP component authentication feature cannot be enabled unless every MDM, SDC and SDS in the system is at least version 3.5, and conversely, if the feature is enabled, no pre-v3.5 SDCs can be added.
  • 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 VxFlex OS v3.0.
