Abstract
Techniques are disclosed for reallocating host resources in a virtualized computing environment when certain criteria have been met. In some embodiments, a system identifies a host disabling event. In view of the disabling event, the system identifies a resource for reallocation from a first host to a second host. Based on the identification, the computer system disassociates the identified resource's virtual identifier from the first host device and associates the virtual identifier with the second host device. Thus, the techniques disclosed significantly reduce a system's planned and unplanned downtime.
Claims19
A method for managing reallocation of resources between host devices, the method comprising:
- detecting an event to disable a first host device selected from a plurality of host devices;
- in response to detecting an event to disable the first host device:
- identifying a plurality of available resources at the first host device;
- determining whether reallocation criteria have been met for at least one of the available resources at the first host device;
- as a result of the determination that the reallocation criteria for the at least one of the available resources at the first host device have been met:
- selecting the at least one of the available resources at the first host device for reallocation to a second host device;
- and
- reallocating the selected available resource from the first host device to the second host device;
- and
- as a result of the determination that the reallocation criteria for the at least one of the available resources have not been met:
- forgoing reallocating the at least one of the available resources from the first host device to the second host device;
- and
- replicating the at least one of the available resources from the first host device to a location distinct from the first host device.
A non-transitory computer-readable storage medium storing one or more programs configured to be executed by one or more processors of an electronic device for managing reallocation of resources between host devices, the one or more programs including instructions for:
- detecting an event to disable a first host device selected from a plurality of host devices;
- in response to detecting an event to disable the first host device:
- identifying a plurality of available resources at the first host device;
- determining whether reallocation criteria have been met for at least one of the available resources at the first host device;
- as a result of the determination that the reallocation criteria for the at least one of the available resources at the first host device have been met:
- selecting the at least one of the available resources at the first host device for reallocation to a second host device;
- and
- reallocating the selected available resource from the first host device to the second host device;
- and
- as a result of the determination that the reallocation criteria for the at least one of the available resources have not been met:
- forgoing reallocating the at least one of the available resources from the first host device to the second host device;
- and
- replicating the at least one of the available resources from the first host device to a location distinct from the first host device.
A computer system, comprising:
- one or more processors;
- and
- memory storing one or more programs configured to be executed by the one or more processors for managing reallocation of resources between host devices, the one or more programs including instructions for:
- detecting an event to disable a first host device selected from a plurality of host devices;
- in response to detecting an event to disable the first host device:
- identifying a plurality of available resources at the first host device;
- determining whether reallocation criteria have been met for at least one of the available resources at the first host device;
- as a result of the determination that the reallocation criteria for the at least one of the available resources at the first host device have been met:
- selecting the at least one of the available resources at the first host device for reallocation to a second host device;
- and
- reallocating the selected available resource from the first host device to the second host device;
- and
- as a result of the determination that the reallocation criteria for the at least one of the available resources have not been met:
- forgoing reallocating the at least one of the available resources from the first host device to the second host device;
- and
- replicating the at least one of the available resources from the first host device to a location distinct from the first host device.
