    摘要: Data storage apparatus comprises a tape drive and a tape cartridge, the tape cartridge having a data storage tape on which write-once-read-many (WORM) data is stored. The data storage apparatus is controlled by providing a format command to the tape drive commanding a formatting operation that conditions the tape for erasure or overwriting of the WORM data. A format command key is provided with the format command to be compared with a key recorded in the cartridge. The format command is enabled in dependence upon the comparison between the format command key and the recorded key.

    摘要: A data storage apparatus comprises a tape cartridge having a cartridge memory which is configured to store data representing a distinctive identity of the memory and data representing a distinctive identity of the cartridge. The cartridge has a data storage tape storing WORM data in a succession of data sets. Each data set is recorded with data representing a respectively associated data set information table. The data set information table includes an identifying data structure including data representing the identity of the cartridge memory and the data representing the identity of the cartridge. The integrity of all the WORM data written at any point along the tape can be checked against tampering by reference to the data structure that is recorded with each WORM data set.

    摘要: A method is provided of detecting if WORM data has been tampered with, the data having been recorded in a sequence of data sets. Each data set includes a write pass value and the write pass values are incremented at intervals in the sequence according to a predetermined rule providing that the write pass values are incremented each time a predetermined number of the data sets has occurred in the sequence. The data sets are read in sequence and the write pass value of each data set is compared with the write pass value of the preceding data set. An indication is made if the write pass value of any of the data sets differs from the write pass value of the preceding data set by an amount that breaches the predetermined rule.

    摘要: First and second ports of a storage switch are respectively coupled to a data source and a first port of a first data sink having a second port coupled to a first port coupled to a first port of a second data sink. The first data sink has a first component for determining whether a data packet received at the first port of the first and second data sink is addressed to the first data sink and a second component for forwarding the data packet from the second port of the first data sink to the first port of the second data sink if the data packet is not addressed to the first data sink.
