    摘要： A system and method for performing a search operation within a sequential access data storage subsystem are disclosed. According to one embodiment, a data storage subsystem is provided which comprises a search module and a communication channel interface to communicatively couple the data storage subsystem to a host data processing system via a communication channel. In the described embodiment, the search module is configured to receive search attribute data from the host data processing system via the communication channel interface, where the search attribute data specifies a search attribute. The search module is further configured to perform a search operation on data of a sequential access storage element utilizing the search attribute and to provide search result data to the host data processing system via the communication channel interface in response to a performance of the search operation.

    摘要： A tape system is provided with an encryption capable tape drive and an encryption enabled tape drive device driver for the encryption capable tape drive. The encryption enabled tape drive device driver functions as a proxy which connects the encryption capable tape drive to a key manager which serves keys to the tape drive. When the encryption capable device driver causes a command to be sent to the drive, the tape drive is configured to respond with a message that is intended for a key manager such as an External Key Manager (EKM). The encryption capable device driver recognizes that this is a message intended for the EKM and forwards that message to the EKM (e.g., via an Internet Protocol (IP) connection). The EKM then responds to the key request by issuing a new key (for a new cartridge which is to be written from beginning of tape (BOT)) or an existing key (for a cartridge which needs to be read). The device driver connects all EKM responses to the encryption capable tape drive and the EKM from which the encryption capable tape drive obtains its keys.
