Abstract: A method for efficient distributed object manager (DOM) owner migration in a virtual storage area network (VSAN) is provided. Embodiments include determining to migrate a DOM owner object from a source DOM owner server to a destination DOM owner server. Embodiments include determining that an input or output (I/O) operation affecting the DOM owner object is in progress. Embodiments include, prior to updating the DOM owner object based on the I/O operation, transferring the DOM owner object from the source DOM owner server to the destination DOM owner server. Embodiments include completing execution of the I/O operation on the destination DOM owner server. Embodiments include updating the DOM owner object on the destination DOM owner server based on the I/O operation.

Abstract: A method for dynamic distributed object manager (DOM) owner migration in a virtual storage area network (VSAN) is provided. Embodiments include determining estimated processor load amounts for a plurality of DOM owner servers based on dispatch latency. Embodiments include determining that a first DOM owner server of the plurality of DOM owner servers has a highest estimated processor load amount of the estimated processor load amounts. Embodiments include determining that a second DOM owner server has a lowest estimated processor load amount of the estimated processor load amounts. Embodiments include determining to migrate a DOM owner object from the first DOM owner server to the second DOM owner server based on a dispatch latency value corresponding to the DOM owner object. Embodiments include migrating the DOM owner object from the first DOM owner server to the second DOM owner server.
