It’s finally here – the latest release of PowerVC, which we have been hard at work on for the past several months. This release fully supports our previous technical previews to give you one totally integrated software-defined infrastructure. We now allow you to manage OpenPOWER systems, export and import images more easily than ever, and even gave the user interface an update. On PowerVC Cloud edition, you can try out our Database as a Service technical preview. Read on for full details about the major updates:
- Database as a Service technical preview (Cloud edition only)
- Integrated software-defined storage
- Support of OpenPOWER and other systems running KVM on Power
- Import and export images
- Use SAN-backed clusters
- Specify multiple IP address ranges and edit IP address ranges
- Create and attach multiple volumes
- Flexible SAN zone names
- Capture a live virtual machine
- Additional project quotas
- Set the Physical Page Table (PPT) ratio
- User interface updates
- Links to fabrics and networks have been removed from the Home page.
- The Import button on the Images page has been renamed Create.
- The Verify environment button has been moved to a new tab on the Home page called Environment Checker. This tab also displays the results of the most recent results of the check.
- The Configuration page has been reorganized.
- The IP Addresses tab on the Network page shows only addresses that are locked or in use.
- The storage count in the navigation pane indicates the number of registered storage providers instead of volumes.
Database as a Service (DBaaS) refers to database instances that are deployed in a cloud, where the user does not need to configure or maintain the database instance or its environment, and can access and use the database just like any other service. PowerVC uses the OpenStack Trove component to deliver these capabilities.
Software-defined storage (converged infrastructure) was previously a technical preview. This support is now included in the official product release. On systems managed by PowerVM® NovaLink, you can use software-defined storage (SDS). SDS requires the software-defined networking (SDN) capability. Together, these two technologies allow administrators to have a predefined node type that has network, storage, and compute all within the server. Then as you increase the number of servers in your environment, the infrastructure elastically and automatically grows.
PowerVC now supports KVM on Power running Ubuntu 16.04. KVM based systems, such as OpenPOWER, can be managed from the same installation of PowerVC that is managing existing PowerVM infrastructure. This support builds on the software-defined networking and the new software-defined storage features.
You can export and import the deployable images between managed storage providers and between data centers from the PowerVC user interface. Use the powervc-image command to import images into PowerVC from outside the managed SAN and export images to a local path in the OVA packaged format.
When using software-defined storage, you can now use either SAN-backed or local disk-backed clusters. Each cluster must be made up of the same types of nodes. That is, all disks must be SAN-backed or all disks must be local disk-backed within each cluster.
When adding or editing a network, you can now specify multiple IP address ranges. Additionally, you can edit the IP address ranges of existing networks.
You can now create or attach multiple volumes at the same time.
PowerVC provides a template format that allows you to customize SAN zone names.
You can now capture running workloads to avoid disruptions in your environment.
These new quotas are supported for projects: Volume Backup (GB), Volume Backups, and Volume Groups.
The PPT ratio controls the size of the page table that is used by the hypervisor when performing live partition migration. The larger the PPT, the more entries are available for use by the partition for mapping virtual addresses to physical real addresses. If the PPT is set too small and the partition is running workloads, performance in the partition can decline during live partition migration.
You can set the PPT ratio on a compute template; either in the user interface or by using the Flavors API. This setting is particularly useful for those running SAP HANA workloads.
Along with a new look and feel, some items on the user interface have been moved, renamed, or have different behaviors:
