Based on a current activity running on a first selection of components operating in a primary mode from among redundant components within a high availability system, a separate power setting is selected for each separate type of redundant component from among the types of redundant components within the redundant components as specified in a high availability status specified for the current activity. At least one controller interface is called with a request to set the powered state of a particular component that is redundant to at least one of the first selection of components, from among a second selection of components operating in a standby mode from among the redundant components, to the separate power setting for the separate type of redundant component.

Managing power savings in a high availability system at a redundant component level of granularity

An approach for management of boot time of a virtual machine is provided. In one aspect, a system boot time application identifies assigned resources of a virtual I/O server (VIOS) of a computing system. In addition, the system boot time application allocates additional resources from client logical partitions (LPARs) of the computing system to the assigned resources of VIOS during boot time of VIOS. The system boot time application further identifies cores of the computing system during the boot time of VIOS. The system boot time application also sets the cores in turbo core mode until boot time of VIOS is completed. In one aspect, the system boot time application reallocates the allocated additional resources from VIOS to the client LPARs once boot time of VIOS is completed.

System and method for expediting virtual I/O server (VIOS) boot time in a virtual computing environment

In an embodiment, a partition is discovered that transferred more than a threshold amount of data between the partition and a first resource. A determination is made that the partition transferred more than a threshold amount of data with a second resource. A determination is made that the data path distance between the first and second resources is more than a threshold. A third location is found that is open and a determination is made that the data path distance between the first resource and the third location is less than a threshold, and in response, a recommendation is made to move the second resource to the third location.
