  • Patent number: 7496539
    Abstract: Dynamic price performance enhancement features and scheduling ranges of input/output performance operating categories and settings for storage solutions are provided by a seller to a purchaser via a program running either remotely on the seller's host system over a communications network or locally on a general purpose computer processor in a tape storage library device. The purchaser is prompted by the seller's system to identify storage device requirements and price constraints. The seller's system provides storage performance operating solutions and negotiates a suitable match between the seller's storage solutions and the purchaser's storage requirements and price constraints. The seller's system finalizes the design of the storage solution and provides a pool of license keys that unlock the storage performance solutions in the tape storage library device that match the purchaser's storage performance requirements and price constraints.

  • Publication number: 20090003609
    Abstract: A method for updating encryption keystores within a computer network having multiple host computers is disclosed. A keystore is initially loaded into a key manager within one of the host computers. In response to a key request by a peripheral device within the computer network, a determination is made whether or not the keystore is currently being updated. In a determination that the keystore is not currently being updated, the loaded keystore is utilized to handle the key request. In a determination that the keystore is currently being updated, any incoming key request is redirected to a local queue associated with the key manager. Afterwards, the updated keystore is utilized to handle the key request and any other key request pending in the local queue associated with the key manager.
