Virtual machine storage management queue

A computer program product comprising a non-transitory computer-readable storage medium storing a set of instructions, which, when executed by a computing device, cause the computing device to:

• receive, by a virtual logical disk manager running on the computing device, a stream of storage management commands directed at logical disks hosted by a data storage system (DSS), the logical disks being accessible to virtual machines (VMs) running on a remote host, each storage management command having a predefined command type of a predefined plurality of command types, each command type of the plurality of command types having a respective predefined timeout period;
• place all the storage management commands of the stream into a single VM storage management queue stored on the computing device without regard for their respective command types, the VM storage management queue being maintained by the virtual logical disk manager;
• and
• selectively dequeue storage management commands stored in the single VM storage management queue to an operations scheduler running as part of a storage management module of the DSS to be performed by the DSS, wherein selectively dequeuing includes applying a set of dequeuing criteria, the set of dequeuing criteria including a criterion that selects storage management commands from the single VM storage management queue according to their respective command types, the operations scheduler being unaware of the predefined plurality of command types, wherein the operations scheduler is configured to assign storage management commands to particular processing cores of the DSS independently of the virtual logical disk manager and the VM storage management queue.

An apparatus comprising:

• network interface circuitry connecting to a remote host;
• and
• processing circuitry coupled to memory, the processing circuitry being configured to:
• receive, via the network interface circuitry, by a virtual logical disk manager running on the processing circuitry, a stream of storage management commands directed at logical disks hosted by a data storage system (DSS), the logical disks being accessible to virtual machines (VMs) running on the remote host, each storage management command having a predefined command type of a predefined plurality of command types, each command type of the plurality of command types having a respective predefined timeout period;
• place all the storage management commands of the stream into a single VM storage management queue stored on the apparatus without regard for their respective command types, the VM storage management queue being maintained by the virtual logical disk manager;
• and
• selectively dequeue storage management commands stored in the single VM storage management queue to an operations scheduler running as part of a storage management module of the DSS to be performed by the DSS, wherein selectively dequeuing includes applying a set of dequeuing criteria, the set of dequeuing criteria including a criterion that selects storage management commands from the single VM storage management queue according to their respective command types, the operations scheduler being unaware of the predefined plurality of command types, wherein the operations scheduler is configured to assign storage management commands to particular processing cores of the DSS independently of the virtual logical disk manager and the VM storage management queue.
