    摘要: An apparatus, system, and method are disclosed for detecting intermittent network link failures. A tracking module tracks link failures of a network link of a network over a specified time interval. A failure module determines the network link is failing in response to a number of link failures exceeding a specified failure threshold. A mitigation module mitigates communications over the network link.

    摘要: An approach to power economization in a spoke and hub environment is presented. When a hub receives a data set from a first spoke, the hub writes the data set to a first partition that is associated with the first spoke. After the data transfer is complete, the hub powers down the first partition. If the first spoke sends additional data transfers to the hub while the first partition is powered down, the hub stores the additional data transfers in a second partition. When the first partition is powered up again, the hub moves the data intended for the first partition and that was stored in the second partition. The data is moved from the second partition to the first partition. The hub may monitor the size of the addition data transfers. If the data transfer is large, the hub may power up the first partition, write the data in the first partition, and move to the first partition any data that was intended for the first partition but written to the second partition while the first partition was powered down.

    摘要: A servo track has identical servo pattern frames including two pairs of parallel magnetic transitions, the transitions of each pair spaced apart an equal distance, the transitions of the first pair at an azimuth angle to the longitudinal axis of the tape, the transitions of the second pair at an opposite azimuth angle. A servo channel receives signals at first times corresponding to when a servo read head detects the first and second transitions of the first pair of parallel transitions of a servo pattern frame, and second times corresponding to when the servo read head detects the first and second transitions of the second pair of parallel transitions. The servo channel determines a relative lateral movement and velocity between the tape and the tape head based on the azimuth angle and the ratio of the difference of the first and the difference of the second times.

    摘要: A method to erase data stored on an erasable optical recording system is provided. The optical recording system includes a laser IO head having a blue-light laser, a red-light laser, and an infrared-light laser writing data on the blu-ray disc, the DVD disc, and CD disc, respectively. The method includes indexing the infrared-light laser of the laser IO head one track of the blu-ray disc every 0.4 revolutions after first 0.8 revolutions, to erase the data stored on the blu-ray disc.

    摘要: An encryption communications appliance provides data encryption management for a data storage library. The appliance is coupled to an encryption-capable storage device, a data storage library controller within the data storage library and with an encryption key manager (EKM). The encryption command communications appliance intercepts encryption key requests from the data storage device and transparently forwards the requests to the EKM. The appliance also forwards transparently communications between the library controller and the data storage device.

    摘要: A method of controlling access to an automated media library receives a request for access to the library from an individual having an identity. Access may include importing media to the library, exporting media from the library, and opening a locked door to a cabinet containing the library. If the access includes the importing media, the method moves a robotic media handler to a locked import/export station. If the access includes exporting media, the method moves the requested media to the locked import/export station. If the access includes the opening the door, the method takes a first inventory of the media in the library. The method authenticates the identity of the individual and determines an access level associated with the individual. If the access level is insufficient for the requested access, the method denies the requested access and issues an alert. If the access level is sufficient for the requested access, the method determines if the requested access requires a second authentication. If a second authentication is required, the method prompts the individual to perform the second authentication. If the second authentication is verified, the method logs the access by the individual and grants the access. If the access is granted and the access is importing or exporting media, the method unlocks the import/export station. If the access is granted and the access is opening the door, the method unlocks the door. The method closes and locks the import/export station a predetermined length of time after unlocking the import/export station. The method locks the door a predetermined length of time after unlocking the door and takes a second inventory of the media. The method issues an alert if the second inventory differs from the first inventory.
