  • Patent number: 11687682
    Abstract: A security cable can include a restraining cable and a lock unit attached to the restraining cable. The lock unit can be configured to removably fasten to a computing device. The lock unit can be further configured to switch the security cable between a first configuration and a second configuration. In the first configuration, the lock unit can be fastened to the computing device and can place the computing device in an inactive state. In the second configuration, the lock unit can be removable from the computing device and may not place the computing device in the inactive state.

  • Patent number: 11245750
    Abstract: A method for balancing load across multiple file servers is disclosed. In one embodiment, such a method includes monitoring load experienced by multiple file servers arranged in an active-active configuration. The method receives, from a client node, a request for an address associated with one of the file servers. The method determines a particular file server of the file servers that, if assigned to the client node, would reduce load imbalance between the file servers. In certain embodiments the particular file server is the file server experiencing the least load. The method returns, to the client node in response to the request, an address associated with the particular file server, thereby enabling the client node to mount the particular file server to access files thereon. A corresponding system and computer program product are also disclosed.
