An apparatus and method are disclosed to generate convolution encoded data. The method supplies a convolution encoder. The method receives original data and generates convolution encoded original data. The method receives revised data. The method generates an XOR data stream by Exclusive OR'ing the original data with the revised data, forms a convolution encoded XOR data stream using the convolution encoder, and Exclusive ORs the convolution encoded XOR data stream with the convolution encoded original data to generate convolution-encoded revised data.

A method is disclosed for configuring a data storage device. A storage module stores configuration data on a remote storage system that may include operating systems, applications, updates, and an index. A boot module boots a computer system from a program other than the regular boot program to provide access to a network in communication with the remote storage system. A device configuration module autonomically downloads and installs the operating systems, applications, and updates in response to data stored in an index on the remote storage system.

A holographic storage drive of a holographic data storage system is configured to write and read holograms with respect to a plurality of locations of a holographic storage medium; and a control is configured to operate the holographic storage drive to write a known image aggregated with data in the form of a hologram to the holographic storage medium; to operate the holographic storage drive to read back the written hologram, employing a partial matched filter to cross-correlate the read-back image with the ideal version of the known image, excluding the remainder of the written hologram; and to determine whether the cross-correlation at least meets a write/readback threshold.

A method and a system are provided for displaying information on a data storage cartridge. The data storage cartridge includes a driver circuit coupled to a display and a cartridge memory. The driver circuit activates the display on the data storage cartridge. In response to the activation of the display on the data storage cartridge the driver circuit obtains information from the cartridge memory of the data storage cartridge. The driver circuit displays at least a portion of the information obtained from the cartridge memory on the display of the data storage cartridge. In one embodiment the data storage cartridge is a tape cartridge.

A method is disclosed to encode information in a holographic data storage medium. The method supplies a holographic information storage system comprising a laser light source, a spatial light modulator, and a holographic data storage medium. The method energizes the laser light source using first power comprising a first current, disposes a data image on the spatial light modulator, and further energizes the laser light source using second power comprising a second current, wherein the second current is greater than the first current. The method forms a data beam comprising said data image, forms a hologram comprising said data image, and encodes an interference pattern comprising the hologram in the holographic data storage medium.
摘要:
A system and method for measuring data transmission activity through a port of a switch device interconnecting nodes of a storage area network, the port transmitting data as words of predetermined length, one data word indicating idle port activity. The method includes steps of: counting a number of transmitted words received from the port in a first counter device; and, for each word counted, comparing that word with a predetermined word indicating no (idle) port transmission activity. In response to the comparing, a number of matches are counted in a second counter device. In this manner, a ratio of a number of counted matches with a total amount of words counted indicates available bandwidth for transmitting additional data over that link. Preferably, this value is communicated to a processor device for controlling bandwidth over the link.
摘要:
A method and system including apparatus for detecting and blocking an invalid request to a target wherein fibre channels interconnect the data processing configuration. A request made from a hub such as a fabric switch to an internal fibre channel arbitrated loop is blocked by substituting IDLE characters for the frames of data included with the request. The substitution of IDLE signals can also occur within an internal fibre channel arbitrated loop system where access is blocked to a confidential data storage system. If the request is legitimate, the data frames are passed to the target and the requested data is transmitted back to the requester. If the request is refused as being an unauthorized request, the data frames are replaced with IDLE characters and no transfer of confidential data occurs.
摘要:
A computing system implements a SAN attached automated Hierarchical Storage Library with diverse media types and media failover capability where storage communications destined for any one media type may be redirected to another media type for uninterrupted storage communications with a host system when a failover condition has occurred. A preferred embodiment comprises: a) a controller network interface for connecting the storage area to a network; b) at least one control unit for HDD and removable media emulation; c) a failover bridge for seamless protocol conversion between media types; d) an HDD interface for connection to a plurality of HDD's on at least one backplane; e) at least one dual redundant controller component with dual mirrored NVRAM's thereby providing dual primary and failover communications links for the plurality of HDD's and removable media drives; f) a removable media interface for a plurality of removable media or removable media emulators.
