  • Patent number: 10733328
    Abstract: A facility monitoring system and/or a secure data storage device transport trolley accounts for data storage devices removed from rack computing devices while in transport. The secure data storage device transport trolley comprises a backplane, backplane connectors, and a computing device coupled to the backplane. The computing device scans for data storage devices connected to the connectors of the backplane at regular intervals and maintains an updated list of data storage devices being transported by the secure data storage device transport trolley. The secure data storage device transport trolley also provides the list to a facility monitoring system for reconciliation.

  • Patent number: 10691842
    Abstract: A tamper detection system utilizes a barrier that includes a bar sized to extend across a rack in an arrangement in which the bar blocks access to an appliance received in the rack. The tamper detection system further utilizes a detector configured to log, transmit, or otherwise generate an indication that the barrier has been tampered with, such as in response to the bar being pulled away from the rack enough to decouple a magnet that when magnetically coupled to the rack maintains a switch in a first state against a biasing force of a biasing mechanism urging the switch toward a second state, or such as in response to the bar becoming severed or pulled away from the rack enough to cause a detectable change of resistance or other electrical characteristic in a corresponding circuit.

  • Patent number: 10169965
    Abstract: A tamper detection system utilizes a barrier that includes a mesh sized to extend across a rack in an arrangement in which the mesh blocks access to an appliance received in the rack. The tamper detection system further utilizes a detector configured to log, transmit, or otherwise generate an indication that the barrier has been tampered with, such as in response to the mesh becoming severed or pulled away from the rack enough to cause a detectable change of resistance or other electrical characteristic in a corresponding circuit.
