  • Patent number: 9122417
    Abstract: A network attached storage device may include at least one storage device, a network connection coupling the at least one storage device to a network and a processor coupled to the at least one storage device and to the network connection. The processor may be configured to monitor a plurality of operating parameters of the network attached storage; determine a state of a network attached storage based on at least two of the monitored plurality of operating parameters of the network attached storage; determine a current level of protection from among a predetermined plurality of levels of protection based on the determined state of the network attached storage, and provide an indication of the determined level of protection afforded by the network attached storage.

  • Patent number: 8868666
    Abstract: A media aggregator device includes a plurality of interfaces, at least one of which may be configured to couple to a local network and at least one processor coupled to the plurality of interfaces. The processor may be operable to access a first device coupled to the local network and catalog media content stored on the first device; access a second device and catalog media content stored on the second device; populate a media aggregator database with references to the media content cataloged in the first and second devices, and present contents of the populated media aggregator database to a client device to enable the client device to access any of the media content referred to in the media aggregator database, subject to appropriate access rights.

  • Publication number: 20080219449
    Abstract: A method is provided for performing application-transparent key management in a storage library associated with an encrypting removable storage device. Encryption and decryption is performed by a key manager and the removable storage device, and is transparent to the application. Data is encrypted using keys that are managed by the storage key manager. An administrative interface allows an administrator to specify and manage encryption keys. A key identifier is associated with each key, and the key identifier is written to the tape along with the encrypted data. When reading encrypted data, the removable storage device reads the key identifier from the tape and requests the corresponding encryption key from the key manager. The removable storage device then provides the decrypted data to the application. The encryption key may be exported from the key manager or library in an encrypted XML format.
