Abstract: Method, system, and program product for assigning device identifiers. A device requests a device identifier from a server. The server obtains the device identifier, marks a status of the device identifier as pending, and sends it to the device. The device sends an acknowledgment back to the server. The server then marks the status of the device identifier as in use and sends a confirmation to the device. The device starts to use the device identifier after receiving the confirmation.

Abstract: Logic for receiving client write requests, bundling them, and sending a reply back to the client(s) once the requests are committed to storage. The logic is included in an intermediate server which includes a write request module having a write bundling module included and a write reply module. A separate reply is sent for each of the individual client write requests. Out of order requests are handled by checking for a contiguous write having a lower file location (offset) than a current write request and placing that lower ordered offset request first in the bundle.
