Abstract: An interconnected computer system includes a Peripheral Component Interconnect Express (PCIe) fabric, a first computer system communicatively coupled to the PCIe fabric, a second computer system communicatively coupled to the PCIe fabric, and a shared single-access hardware resource coupled to the PCIe fabric. The first computer system includes a first processor and first memory coupled to the first processor configured to store a first flag indicating a desire of the first computer system to access the shared single-access hardware resource and a turn variable indicating which of the first computer system and the second computer system has access to the shared single-access hardware resource. The second computer system includes a second processor and second memory coupled to the second processor configured to store a second flag indicating a desire of the second computer system to access the shared single-access hardware resource.

Abstract: A computer-implemented method for on-demand data replication in a network architecture includes activating an on-demand program to pair a network-based replication agent with a data source. Compute resources for the replication agent are allocated based on one or more hints received from the data source. The one or more hints are indicative of at least a size of an upcoming data traffic transmission from the data source. Upon receiving data from the data traffic transmission, the replication agent is activated via the on-demand program to replicate the received data using the allocated replication resources. The allocated compute resources are released upon completion of data replication of the received data. The on-demand program is a serverless function configured to activate the replication agent on-demand, upon receiving the data from the data traffic transmission.

Abstract: An efficient structure and methodology for container-based applications are provided for disaster recovery for data in a storage system using application consistency groups for replication from the storage system to a disaster recovery system. Application consistency groups can be generated containing applications, a disaster recovery plan, and a disaster recovery policy, where each application has a consistency level. The applications in an application consistency group can include stateless applications and stateful applications. The replication of an application consistency group from the system to a disaster recovery storage system can be controlled according to the disaster recovery policy, the disaster recovery plan, and the consistency levels of the application consistency group.

Abstract: A clustered storage system includes a plurality of storage devices, each of which contributes a portion of its memory to form a global cache of the clustered storage system that is accessible by the plurality of storage devices. Cache metadata for accessing the global cache may be organized in a multi-layered structure. In one embodiment, multi-layered structure has a first layer first including a first address array, and the first address array include addresses pointing to a plurality of second address arrays in a second layer. Each second address array in the second layer includes addresses, each of which points to data that has been cached in the global cache.
