Abstract: Embodiments are described for dynamically allocating and reallocating system resources between production work tasks and administrative tasks using policies. A resource monitor continuously monitors all resources in a computing system, and whether the resources are used for production work or administrative tasks. A policy can define resources needed to execute an administrative task and conditions which can be used to determine whether or not the administrative command is allocated the resources, even at the expense of a negative impact to production work.

Abstract: Embodiments are described for a multi-node file system, such as a clustered or distributed file system, with a file system buffer cache and an additional host-side tier non-volatile storage cache such as 3DXP storage. Cache coherency can be maintained by one of three models: (i) host-side tier management, (ii) file system management, or (iii) storage array management. performing a storage tier-specific file system action in a file system that comprises a namespace that spans multiple tiers of storage.

Abstract: A technique provides data storage system services in data storage equipment. The technique involves performing, by processing circuitry of the data storage equipment, data storage operations on a production volume in response to data storage commands from a set of application servers (e.g., external host computers). The production volume stores application server data utilized by the set of application servers. The technique further involves running, by the processing circuitry of the data storage equipment, an instance of a virtual backup appliance within the data storage equipment while the data storage operations are performed on the production volume in response to the data storage commands. The technique further involves generating, by the processing circuitry of the data storage equipment, backups of the production volume via the instance of the virtual backup appliance running within the data storage equipment.
