PDF

Install and upgrade

You can install and configure PowerFlex version 4.0.x, or you can upgrade from PowerFlex version 3.6.x to version 4.0.x.

PowerFlex Manager allows you to use the Initial Configuration Wizard to perform an upgrade to version 4.0.x. Customers with PowerFlex 3.5.x can upgrade to 3.6.x, and then use the Initial Configuration Wizard to perform an upgrade to PowerFlex Manager 4.0.x.

Customers with PowerFlex Manager must be running PowerFlex Manager 3.8 in order to perform the upgrade.

Customers that do not have an existing PowerFlex environment have the option to deploy a new instance of PowerFlex.

See the Dell PowerFlex Install and Upgrade Guide for more information.

Supported operating systems

The user documentation contains a list of supported operating systems. For the most current information, see the Dell Simple Support Matrix (ESSM) at https://elabnavigator.dell.com/eln/modernHomeSSM, Storage option.

SDC compatibility

By design, the PowerFlex SDC in this release is compatible with newer and 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 and forward 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.
