Abstract
Systems, methods and computing components are provided for allocating a plurality of computing components among one or more logical partitions. Each of the plurality of computing components may have a management processor that is configured to assume a role among management processors of a partition. Each management processor may then cooperate with other management processors of the partition to control resources of the partition.
Claims18
A system comprising a plurality of computing components in a logical partition, each of the plurality of computing components having a management processor that is configured to:
- assume a role among management processors of a partition;
- cooperate with other management processors of the partition to control resources of the partition, wherein one of the management processors serve as an exclusive liaison and interface through which device health information or power/reset commands for all the management processors of the partition are routed for communications between the management processors and an outside entity;
- assume a role of primary or auxiliary management processor of a partition;
- enable an external interface, if the external interface is disabled, where the management processor has assumed the role of primary management processor of a partition;
- and
- disable the external interface, if the external interface is enabled, where the management processor has assumed the role of auxiliary management processor of a partition.
A method of allocating a plurality of computing components among a logical partition, comprising:
- distributing a partition description to each of the plurality of computing components that assigns a management processor of the computing component a role as a primary or auxiliary management processor in a partition;
- providing access to resources of a partition exclusively at the primary management processor of the partition;
- providing an external interface to health information for each of the plurality of computing components and for power/reset commands for each of the plurality of computing components exclusively through the primary management processor;
- enabling the external interface, if the external interface is disabled, where the management processor has assumed the role of primary management processor of a partition;
- and
- disabling the external interface, if the external interface is enabled, where the management processor has assumed the role of auxiliary management processor of a partition.
A computing component for use in a system of a plurality of computing components in a logical partition, the computing component having a management processor comprising:
- means for assuming a primary or auxiliary role in a partition;
- means for cooperating with other management processors of the partition to control resources of the partition, wherein the management processor assuming the primary role in the partition serves as an exclusive liaison and interface through which device health information or power/reset commands for all the management processors of the partition are routed for communications between management processors and an outside entity;
- means for enabling the external interface, if the external interface is disabled, where the management processor has assumed the role of primary management processor of a partition;
- and
- means for disabling the external interface, if the external interface is enabled, where the management processor has assumed the role of the auxiliary management processor of a partition.
