  • Patent number: 6397229
    Abstract: A storage-controller-managed outboard incremental backup/restore of data. An indicator is assigned to an associated portion of data stored in a data storage device, wherein the indicator resides in a memory of a storage controller coupled to the data storage device. A value of the indicator residing within the memory of the storage controller is set when the associated portion of the data has changed. The associated portion of the data stored in the data storage device is backed using the storage controller when the value of the indicator residing within the memory of the storage controller is set. The value of the indicator residing within the memory of the storage controller is cleared when the associated portion of the data has been backed up.

  • Patent number: 6332197
    Abstract: Disclosed is a system for updating and destaging data in a storage system. To overcome the limitations in the prior art described above, preferred embodiments of the present invention disclose a system for updating a data block in a storage device. A first processing unit receives an update to a data block in a storage device. The first processing unit sends a first message including the update and information indicating data blocks that were recently updated to a second processing unit. The second processing unit stores the update in a second storage area and sends a second message to the first processing unit after receiving the first message. The first processing unit stores the update in a first storage area and transfers the update from the first storage area to the data block in the storage device. The first processing unit transfers the update from the first storage area to the data block in the storage device.

  • Patent number: 6326458
    Abstract: A process for the continuous production of substantially purified lactide and lactide polymers from lactic acid or an ester of lactic acid including the steps of forming crude polylactic acid, preferably in the presence of a catalyst means in the case of the ester of lactic acid, to form a condensation reaction by-product and polylactic acid, and depolymerizing the polylactic acid in a lactide reactor to form crude lactide, followed by subsequent purification of the crude lactide in a distillation system. A purified lactide is then polymerized to form lactide polymers.

  • Patent number: 6279138
    Abstract: Disclosed is a system for altering the structure of parity groups, e.g., altering the RAID level or number of storage devices included in the RAID array. A parity group consists of a set of data blocks and parity data for the data blocks. The data and parity data are stored in at least two storage devices. The first processing unit alters the parity structure of an Nth set of parity groups, wherein N is an integer value greater than or equal to zero. A set of parity groups includes at least one parity group. The second processing unit determines an Nth range of parity groups including the Nth set of parity groups. After detecting the failure of the first processing unit while altering the parity structure of the parity groups in the Nth set, the second processing unit processes the parity groups in the determined Nth range to determine a parity group whose parity structure was being altered when the first processing unit failed.

  • Patent number: 6272662
    Abstract: Disclosed is a system for performing an operation, such as a read or write operation, on a data block in a shared disk system. A first adaptor receives a request to perform an operation on a data block maintained in a data storage location. The first adaptor then determines whether the first adaptor controls access to the data block. The first adaptor performs the requested operation on the data block after determining that the first adaptor controls access to the data block. If the first adaptor does not control access to the data block, then the first adaptor transmits a first message to a second adaptor that controls access to the data block and requests control of access to the data block. After receiving the first message, the second adaptor transfers control of access to the data block to the first adaptor. The second adaptor then transmits a second message to the first adaptor that the first adaptor controls access to the data block.

  • Patent number: 6208804
    Abstract: A multimedia direct access storage device and a method for transferring source program signals representative of a compressed digital multimedia program to and from the direct access storage device are disclosed. A multimedia program is transmitted from a multimedia server as a custom ordered series of discrete program segments and received by the multimedia direct access storage device, which buffers the compressed program segments for subsequent presentation on a local display monitor. The multimedia direct access storage device is preferably incorporated as a component of a local set-top control system for buffering a predetermined number of compressed program segments received from the multimedia server, some of which may be non-sequentially ordered and others of which may be sequentially ordered. A novel formatting methodology provides for the sequential presentation of the program segments asynchronously distributed on one or more data storage disks disposed in the direct access storage device.

  • Patent number: 6185685
    Abstract: A multi-stage login procedure and system involves a first stage in which a login ID and a public key (encrypted) is transmitted from a client computer to a server computer and a key-exchange key (encrypted) is provided from the server computer to the client computer. In a second stage, a first split symmetric key and a server authentication string is generated and encrypted by the client computer and then transmitted to the server computer. In addition, the server computer generates a second split symmetric key and combines the same with the first split symmetric key to obtain a complete symmetric key for encrypting further communications from the server to the client computer. The server also generates a client authentication string, encrypts the same and transmits the encrypted string, the server authentication string (encrypted and incremented) and the second split symmetric key (encrypted) to the client computer.
