PowerVC Release Content


PowerVC 1.3.2 (Announced October 2016)

New support


Additional LDAP servers

IBM Tivoli Directory Server 6.3 and its replacements: IBM Security Directory Server and IBM Security Directory Suite, are now supported.

Virtual machines with vSCSI connections to Hitachi volumes

Existing virtual machines with virtual SCSI (vSCSI) volume connections to the Hitachi array are now supported for management in PowerVC.

Activation engine deprecation

Activation engine on IBM i is deprecated and will be withdrawn from support in the next release. It is strongly recommended that new IBM i images are constructed with cloud-init. Cloud-init is the strategic image activation technology of IBM. It offers a rich set of system initialization features and a high degree of interoperability.


Functional enhancements


Software-defined networking (technical preview)

Software-defined networking (SDN) virtualizes your network in a similar way that compute resources are virtualized. It allows you to change virtual machine communication without changing your physical network. PowerVC supports SDN on PowerVM® NovaLink managed systems when PowerVC is installed in Technical Preview mode. For details, see Technical preview: Planning for software-defined networking.

Single Root I/O Virtualization (SR-IOV) support

PowerVC supports SR-IOV network interface connectivity for virtual machines with NovaLink managed hosts. This support includes the ability to set the Virtual NIC capacity, which is the first Quality of Service setting available for PowerVC. This support does not include live partition mobility (LPM) and remote restart functions for SR-IOV backed networks. For details about SR-IOV, see SR-IOV backed networks.

Virtual console

PowerVC supports access to a virtual console for NovaLink-managed virtual machines. To access a virtual console for your virtual machine, go to the Virtual Machine Details page and select the Console tab to launch a VNC session.

Consistency group API support on additional storage devices

The Cinder consistency group and consistency group snapshot APIs are supported on EMC VMAX, EMC VNX, Hitachi Data Systems, and IBM DS8000 storage devices. For details, see Planning for storage and Supported OpenStack Block storage (Cinder) APIs.

Note: The create_from_src API is not supported on EMC VMAX storage devices.

Snapshot support on additional storage devices

The Cinder snapshot APIs are supported on EMC VMAX, EMC VNX, Hitachi Data Systems, IBM DS8000, and IBM XIV storage devices. For details, see Planning for storage and Supported OpenStack Block storage (Cinder) APIs.

Host memory rebalancing

IBM PowerVC Dynamic Resource Optimizer can now migrate virtual machines from overburdened NovaLink hosts based host memory utilization. For details, see Dynamic Resource Optimizer.

Automated remote restart

Automated remote restart monitors hosts for failure by using the PRS (Platform Resource Scheduler) HA service. If a host fails, PowerVC automatically remote restarts the virtual machines from the failed host to another host within a host group. For details, see Automated remote restart.

Shared storage pool provider support on NovaLink

PowerVC can use the NovaLink shared storage pool management capability in these new ways: to automatically discover and use shared storage pool storage providers through NovaLink cluster members, and to support volume connectivity from shared storage pools to virtual machines hosted by NovaLink partitions. For details, see Planning for shared storage pools.

Initiator zoning

Initiator zoning is a mode of Fibre Channel zoning. With initiator zoning, a zone is created for each initiator and includes all of the controller targets that are supplied by the volume driver in the initiator target map. This results in fewer zones being created. You can choose whether to use initiator target zoning or initiator zoning when registering a fabric via the user interface or the Register a SAN fabric or switch API.

User and group filtering

You now control which users and groups will be visible to PowerVC when using the local operating system as the identity repository. Previously, user and group filtering was only available when using LDAP. For details, see Configuring operating system users and groups.

Inject an SSH key

When deploying a virtual machine from PowerVC, you can inject an SSH public key into the deployed virtual machine. Users can then use the corresponding private key to connect to the deployed virtual machine. For details, see Injecting an SSH key.

Principle Brocade switch is no longer required

The requirement that you register a principle Brocade switch has been removed.

Replace messaging certificates

You can now replace the certificates used to secure AMQP messaging if you believe a certificate has been compromised or if you need to change a property. For instructions, see Providing new certificates for messaging.

Dependency prerequisite check

The prerequisite checks have been enhanced to check for any packages that are not installed or available via any yum repositories. Running the install with the -t option displays any missing packages along with any other failed prerequisite checks.


API and CLI command updates


New APIs

These APIs have been added:

host-sriov

Configures SR-IOV adapters during deployment. See Configure SR-IOV adapters for details.

SDN technical preview

PowerVC supports the additional OpenStack networks (neutron) APIs for SDN technical preview. See Supported OpenStack Networks (Neutron) APIs for details.

CLI updates

New and changed CLI commands are listed. For instructions to use the command, open a command line and enter the command name followed by --help.

powervc-services

This command also allows you to control services for NovaLink managed hosts.


PowerVC 1.3.1 (Announced April 2016)


IBM Cloud PowerVC Manager

Cloud PowerVC Manager works with PowerVC Standard to provide an end-to-end cloud solution. Cloud PowerVC Manager allows you to provision workloads and manage virtual images, in addition to all PowerVC Standard functionality.

With Cloud PowerVC Manager, administrators can create deploy templates that include an image, its attached volumes, and all necessary deployment settings. Users can then create a virtual machine from that deploy template with just a few clicks. Administrators can also set policies in projects to control what user actions require administrator approval.

Enhancements to PowerVC Standard Edition:

PowerVM® NovaLink enhanced support

  • NovaLink supports Capacity on Demand operations when using DRO.
  • Virtual machines can use any shared processor pool.
  • Remote restart is supported on NovaLink hosts.

Deprecated support

  • VSAE has been withdrawn from support.
  • Activation engine on IBM i is deprecated.

Functional enhancements

Projects

Projects allows you to group resources together. Only users who have authority to a project can view or use the resources in that project.

Schedule Dynamic Resource Optimizer

On each host group, you can set up a weekly schedule that specifies when Dynamic Resource Optimizer (DRO) operations are enabled on the host group.

Select which volumes to delete

When deleting a virtual machine, you can select which volumes should be deleted. You can choose to delete only the boot volumes, all attached volumes, or specify a custom list. However, shared volumes will never be deleted.


PowerVC 1.3.0 (Announced October 2015)


Support for IBM PowerVM® NovaLink

PowerVC can manage systems that are being managed by Hardware Management Console (HMC) or NovaLink. Your environment can be comprised of systems that are managed by both types of management systems.

IBM System Storage® DS8000®

For requirements and restrictions, such as firmware and license requirements, refer to IBM XIV® and DS8000 volume driver.

Deprecated support

  • VSAE deprecation
  • RHEL 5.x deprecation

Functional enhancements

New security roles

With PowerVC Version 1.3 Fixpack 2, new roles were added to allow you to manage your user capabilities with more granularity.

Change between NovaLink and HMC management

With PowerVC Version 1.3 Fixpack 2, if you have a host that was added to PowerVC as HMC managed, you can change it to be NovaLink managed. However, you must ensure that PowerVC recognizes the change and can continue communicating with it.

With PowerVC Version 1.3 Fixpack 2, if you have a host that is NovaLink managed, you can change it to be HMC managed. However, you must ensure that PowerVCrecognizes the change and can continue communicating with it.

Migrate virtual machines regardless of management type

With PowerVC Version 1.3 Fixpack 2, virtual machines can be migrated from hosts that are HMC managed to hosts that are NovaLink managed and the reverse. The normal rules surrounding migration still apply.

Dynamic Resource Optimizer

IBM PowerVC Dynamic Resource Optimizer (DRO) continuously monitors the resource utilization of physical hosts and virtual machines in a cloud environment. When usage imbalances are detected, the PowerVC DRO optimizes the cloud, making adjustments for workloads whose characteristics change over time. Capacity on Demand (CoD) fromIBM Power Systems is a powerful tool that allows you to activate unused cores for a host, giving it more computing power instantly. On eligible systems, the PowerVC DRO works with CoD to relieve overburdened systems. For systems that are not enterprise pool members, the DRO migrates virtual machines to ease the burden on overused hosts.

Add up to 25 fabrics

PowerVC supports adding up to 25 fabrics. They can be redundant, but they do not have to be.

New storage connectivity group settings

New settings have been added to help you control how much fabric redundancy is required in your environment.

AME support

PowerVC Version 1.3 Fixpack 2 supports deploying virtual machines that use Active Memory Expansion (AME).
