What's new in version 2.1.0

PowerVC high availability and scale architecture

Earlier versions of PowerVC followed the All-in-One (AIO) deployment model that involved installing packages and setting up services corresponding to stateless (OpenStack based services like nova, cinder, etc.) and stateful services (MariaDB, RabbitMQetc) on a single system; thus, not following the distributed approach that OpenStack supports. While All-in-one deployment model keeps PowerVC deployment simple and highly manageable, the model denies PowerVC the scale and high availability that it might achieve with a multinode model. For details, see PowerVC high availability and scale architecture.

PowerVC support for P10

PowerVC 2.1.0 supports managing a Power10 host via HMC or NovaLink.

PowerVC Topology overview (VM > Hosts > VIOS > Fabrics > Storage)

Starting PowerVC version 2.1.0, the Topologyfeature provides you with a holistic view of resources in a project. A simple search for any given virtual machine in a project and PowerVC generates an end-to-end path from VM to storage and further to volume in one click. In addition to viewing the resource connections, you can click on a component to view more details. This visualization at the resource level helps you to debug and detect errors. For details, see Topology overview.

Click the customization icon and then select or deselect the columns as required. Click up or down arrows to customize the appearance of columns. This feature is enabled for VM List, Image list, Host list, Volumes list, and Storage template pages. PowerVC retains the customization preferences for specific users until further modifications.

HPE storage integration (ID: PVC-I-106)

Starting PowerVC version 2.1.0, HPE storage is supported as an integrated driver. You can now add an HPE storage driver by using the GUI and work with it. For details, see Planning for HPE storage.

Configure non-hscroot user for HMC registration (ID: PVC-I-250)

The admin user can configure a non-hscroot user with task privileges similar to that an admin user on HMC but only those that are required for registering and handling REST calls coming from PowerVC. For details, see Configure non-hscroot user for HMC registration.
