摘要： A method to select a deduplication protocol for a data storage library comprising a plurality of data storage devices configured as a RAID array, establishes a normal deduplication protocol, a RAID failure deduplication protocol, and a multiple storage device failure deduplication protocol. The method receives host data comprising a plurality of interleaved data blocks. If the system is operating without any storage device failures, then the method processes the host data using the normal deduplication protocol. If the system is operating with a storage device failure, then the method processes the host data using the RAID failure deduplication protocol. If the system is operating with multiple storage device failures, then the method processes the host data using the multiple storage device failure deduplication protocol.

摘要： A dual-path optical recording medium (100) and an apparatus (200) for accessing such are disclosed. The dual-path optical recording medium (100) includes a substrate (114), an intermediate recording layer (118), a holographic recording layer (104) and a dichronic mirror layer (110). The intermediate recording layer (118) is a rewritable data storage layer with a relatively low storage capacity. The holographic recording layer (104) is a write-once data storage layer with a relatively high storage capacity. The dichronic mirror layer (110) is located between the holographic recording layer (104) and the intermediate recording layer (118). The apparatus (200) for accessing the dual-path optical recording medium (100) includes a first light module (131) capable of generating a first laser light (121), and a second light module (132) capable of generating a second laser light (122).

摘要： A load balancing method and system for identifying an input / output (I/O) network path from a set off I/O network paths is provided by the invention. The set off I/O network paths connect a host system via a network to a storage subsystem. The host system comprises at least one host bus adapter (HBA) and the storage subsystem comprises at least one I/O device and the network comprises at least one network device. Each of the HBA, the I/O device and the network device comprise at least one I/O port. For each I/O port of each HBA, an HBA port limit is determined. Additionally the set of I/O network paths which connect the I/O port of each of the HBA via the I/O ports of the network device to the I/O port of the I/O device is identified. Then a fabric utilization limit is determined for each I/O network path and a HBA port utilization is determined for each I/O port of the at least one HBA. All network paths are discarded for which the HBA port utilization is greater than the HBA port limit. For each of the remaining paths a network path distance is determined. All I/O network paths for which the network path distance is greater than the path distance limit are discarded. Then for each of the remaining paths a fabric utilization is determined. All I/O network paths for which the fabric utilization is greater than the fabric utilization limit are discarded and the I/O network path is determined from the remaining network paths.

摘要： A system and method for reading files stored on a storage system is disclosed. The method includes communicatively coupling one or more remote systems for reading files stored in storage with a first set of files according to a predetermined data format and in a cache memory with a second set of files, the second set of files being a subset of the first set of files. Next one or more remote systems are received at least one read request for reading a sequence of files. A determination is made, among the files of the sequence of files, whether one or more cached files are already stored in the cache memory and whether one or more remaining files are not already stored in the cache memory. Creating, within the one or more remaining files, an order according to which the remaining files should be read on the storage system.

摘要： A holographic storage drive and control of a holographic storage system are configured to write at least a group of holograms in a predetermined pattern in the holographic storage medium, and to write a directory hologram which relates to the holograms of the group to form an anchor location of the predetermined pattern. Further, a directory comprising the directory hologram stored in a memory, and the control is configured to initiate a read operation of at least one hologram of a group with an access for the directory hologram of the group at the anchor location; to read the accessed hologram, employing a matched filter to cross-correlate the read accessed hologram with an ideal version of the directory hologram derived from the directory stored in the memory; and to determine whether the read accessed hoIogram is the directory hoIogram of the group.

摘要： 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.
