Abstract: A multi-power-domain emulated persistent memory resource system includes a memory interface/data mover subsystem coupled to a second memory subsystem in a second power domain, and a microvisor subsystem coupled to the memory interface/data mover subsystem and a first memory subsystem in a first power domain that is different than the second power domain. The microvisor subsystem presents an emulated persistent memory resource to a client device using the first memory subsystem, and monitors metadata for the first memory subsystem to identify modification(s) of data in the first memory subsystem. In response, the microvisor subsystem uses the memory interface/data mover subsystem to copy the data from the first memory subsystem to the second memory subsystem. Following unavailability of the first power domain and corresponding loss of the data on the first memory subsystem, the memory interface/data mover subsystem copies the data from the second memory subsystem to the first memory subsystem.

Following an unavailability of the first domain power system that results in a loss of the data on the first memory subsystem, the memory interface/data mover subsystem copies the data from the second memory subsystem to the first memory subsystem.

The resource management system monitors a first subset of resources the compute node(s) that are being used to provide an SDS system using the storage devices that are assigned to the first subset of resources, determines that first subset of resources require adjustment, and identifies a second subset of resources in the compute node(s) to provide the SDS system, with the second subset of resources different than the first subset of resources. The resource management system then reassigns at least one of the storage devices from at least one of the first subset of resources to at least one of the second subset of resources, and provides the SDS system using the at least one second subset of resources.

The resource management system receives a first workload instruction to perform a first workload, identifies a first workload resource utilization pattern of the first resource device over time by the first workload, and identifies a second workload resource utilization pattern of the first resource device over time by a second workload that is different than the first workload. The resource management system then determines whether an aggregated resource utilization pattern of the first workload resource utilization pattern and the second workload resource utilization pattern exceeds a threshold resource utilization characteristic. If not, the resource management system provides the first workload and the second workload using the first resource device.

Abstract: A Logically Composed System (LCS) data provisioning system includes an orchestrator device that includes a cache subsystem and that is coupled to client devices and storage subsystem(s). When the orchestrator device identifies that a first client device has exclusive access to the storage subsystem(s), it activates read data caching for the storage subsystem(s).

When the orchestrator device identifies that the first client device no longer has exclusive access to the storage subsystem(s), it deactivates the read data caching for the storage subsystem(s).
