Abstract: Embodiments are directed to a method performed by a computing device. The method includes (a) receiving, by the computing device, a stream of storage management commands directed at logical disks hosted by a DSS, the logical disks being accessible to VMs running on a remote host, each storage management command having a command type of a plurality of command types, each command type of the plurality of command types having a respective timeout period, (b) placing the storage management commands of the stream into a VM storage management queue stored on the computing device, and (c) selectively dequeueing storage management commands stored in the VM storage management queue to be performed by the DSS, wherein selectively dequeueing includes applying a set of dequeueing criteria, the set of dequeueing criteria including a criterion that selects storage management commands from the VM storage management queue according to their respective command types.

Abstract: Described are techniques for synchronizing operations performed on objects. Locking tables may be received where each of the locking tables corresponds to different object class. First processing may be performed by a first thread to acquire a set of one or more locks. Each lock in the set may be a lock for one of the objects. The first processing may include traversing the locking tables in accordance with a predefined ordering and acquiring the set of one or more locks, wherein, for each lock in the set, a first entry is updated in a first of the locking tables to indicate that the first thread has acquired the lock on one of the objects included in an associated object class corresponding to the first locking table.
