Abstract: An example method of controlling a storage system that includes a replication group. The method may include adding a virtual volume to the replication group by storing a journal entry for the virtual volume at a source site. The journal entry may include: metadata for hooking the virtual volume to a corresponding replica volume; and data indicating a status of the virtual volume. The method may further include sending a message to a replica site instructing it to create the corresponding replica volume for the virtual volume and store a replica journal entry for the replica volume. The method may also include determining whether to set the status of the virtual volume to pending admittance or newly admitted based on whether the replica site was able to successfully create the replica volume and store the replica journal entry.

Abstract: Example embodiments relate to multiplexing network connections. In this manner, the embodiments disclosed herein enable receipt of a request from a user to access a computing device. A first user group associated with the first user may be identified. A determination may be made as to whether the first user group has control over any network connections of a set of network connections available from the computing device. Responsive to the first user group not having control over any network connections available from the computing device, the request may be included in a priority queue for requests. Responsive to a network connection becoming available, a request from the priority queue may be selected and control of the network connection may be made available to user group associated with the user from which the request was received.
