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.

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: 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.
