PowerVC includes some default settings and templates that enable you to get started quickly. However, if you have a more complex environment or have very specific requirements for how resources are deployed and allocated in your environment, then these default settings may not be adequate for your needs.
The Configuration page in PowerVC enables you to customize these settings for your environment. The following items can be created or customized on this page:
|Collocation rules||Collocation rules are used to specify that selected virtual machines must always be kept on the same host (affinity) or can never be placed on the same host (anti-affinity). These rules are enforced when a virtual machine is relocated. In OpenStack, collocation rules are called Server Groups.|
|Users and groups||View the users and groups that have roles in the current project.|
|Compute templates||Enable you to specify the processor, memory, virtual processors, and other settings for images that are deployed using the template. They enable you to quickly and consistently deploy virtual machines with identical characteristics across your environment. Some default templates are provided with PowerVC, and you can edit those or create new ones for your own use.|
|Storage templates||Enable you to specify the properties of a storage volume, such as thin provisioning and compression. Each template is specific to one storage provider. They make it easy to quickly and accurately deploy storage volumes and images. A default storage template is created for you when you register a storage system with PowerVC, and you can edit that template or create new ones for your own use.|
|Storage connectivity groups||Enable you to group Virtual I/O Server virtual machines with storage that they can all access. They make it easier for you to reliably deploy virtual machines so they have access to storage that is dedicated to a particular purpose. They also ensure that a virtual machine that is migrating from one host to another will have access to the same storage resources on the destination host that it does on the source host. One or more default storage connectivity groups are created for you, and you can create new groups to meet the needs of your environment.|
|Fibre channel ports||Enable you to direct deployments on external storage controllers from specific Fibre Channel host ports. In PowerVC, you can add tags to your Fibre Channel ports. These are used in conjunction with storage connectivity groups to specify whether PowerVC should use the port for attachments. You can also specify that a particular port be able to use only NPIV, only vSCSI, or both connectivity types.|
