Techniques for managing data mobility domains in storage system environments. The techniques employ a multiple master approach, in which each storage system in a storage system domain can function as an owner of the domain. Each domain owner has privileges pertaining to addition of new members to the domain, removal of members from the domain, and modification of domain credentials. When a new storage system is added as a member of the domain, the domain credentials are provided from the domain owner to the new storage system, resulting in the domain credentials being shared among all members of the domain. Domain membership information is also shared among all members of the domain. In this way, the management of storage system domains can be achieved without the need of a domain management server, avoiding a single point of failure or latency and reducing the complexity/cost associated with the domain management server.

Systems and methods of serverless management of data mobility domains

A method, computer program product, and computing system for determining, at the computing device, one or more dependencies associated with a plurality of managed objects and a plurality of backend objects. One or more backend notifications associated with one or more backend objects of the plurality of backend objects may be received. One or more managed objects of the plurality of managed objects associated with the one or more backend objects of the one or more backend notifications may be identified, based upon, at least in part, the one or more dependencies associated with the plurality of managed objects and the plurality of backend objects. The one or more identified managed objects of the plurality of managed objects may be updated based upon, at least in part, the one or more backend notifications.

Data management system and method

Techniques are disclosed for managing access to shared computing resources in a computing system which include representing resources as objects and managing access to those objects using the construct of a resource instance manager. A set of resource instance managers responds to all commands requesting access to a set of respective shared resources. Access to each shared resource is managed by a unique resource instance manager for that resource which maintains a consistent state for that shared resource. Each resource instance manager determines, in response to receiving requests to allow execution of commands and using a set of predefined rues, whether those commands may be safely executed concurrently with other commands acting on the same shared resource. If the commands cannot be executed concurrently, the resource instance managers change the order in which queued commands are executed or abort execution of one or more commands.

Dynamic management of concurrent access to shared computing resources

A command request may be made to create a new entity in a data storage system. The new entity may be depend upon one or more base objects required to exist prior to creating the new entity. The command request may be processed in accordance with a selected policy affecting the required base objects. The selected policy may be one of a defined set of policies affecting actions taken with respect to the required base objects and new entity. For example, the policies may provide for automatically creating the required base objects and new entity; automatically selecting existing base objects used to create the new entity; generating a command list of recommend commands for creating the required base objects and the new entity; and generating a recommend list of existing base objects and a command for creating the new entity using at least one of the existing base objects.

Techniques are disclosed for provided automatic fault tolerance in data storage systems and other computer systems managing access to shared computing resources using the construct of a resource instance manager together with an architecture for designing and implementing task-oriented state-based commands for accessing the shared computing resources. A set of resource instance managers respond to all commands requesting access to a set of respective shared resources. Access to each shared resource is managed by a unique resource instance manager for that resource which maintains a consistent state for that shared resource. When commands are designed appropriately, the system can be restored using a system state history maintained transparently by a system-provided application program interface.

A hypodermic needle disposal system includes a housing forming an array of parallel cells, each to receive a tube containing a bonding resin. Each tube includes a rupture seal on its front end. A used needle is directed into a tube to pierce its rupture seal and embed itself in resin. When the resin bonds on the needle, the needle and tube are together removed from the cell for disposal. Tubes are restrained from free movement and from sliding out of their cells by a gravity locking engagement with the housing.
