摘要： A storage switch in accordance with an embodiment of the invention is a highly scalable switch that allows the creation of a SAN that is easy to deploy and that can be centrally managed. Moreover, such a storage switch also allows the deployment of a global infrastructure, allowing the resources of the SAN, such as storage devices, to essentially be positioned anywhere on the globe. Further, such a storage switch allows a multi-protocol SAN, e.g., one that includes both iSCSI or Fibre Channel, and processes data packets at "wire speed". To further enable wire-speed processing, a switch in accordance with the invention has "intelligence" distributed to each of its linecards, through which it classifies packets into data and control packets, it performs virtualization functions, and it performs protocol translation functions. A switch in accordance with the invention further performs serverless storage services such as mirroring, snapshot, and replication.

摘要： PROBLEM TO BE SOLVED: To provide a deskew circuit which corrects skew between a clock and data and between various data of a data bus in data transfer which transfers mass data at high speed between packages and transfers the clock and the data in parallel. SOLUTION: A variable delay circuit is provided between a receiver which receives the data and a flip-flop which latches the data first by every bit of each of the clock and the data. A detection pattern for detecting the stable region of reception data is repeatedly transmitted before performing the data transfer, the delay value of the variable delay circuit is calculated so that the starting point and end point of the data match the rising edge of the clock, and the delay circuit is set to a delay value at which transfer data are stably received.

摘要： PROBLEM TO BE SOLVED: To shorten time consumed for adaptation of each circuit constituting a read channel.
SOLUTION: An HDC 4 asserts the read gate of an RDC 100 when a reproduction head exists at a position of a sector in front of a sector the reproduction of which is instructed from a host system when observing from the rotating direction of a recording medium 1. Data read from the sector by the reproduction head is used for adapting the circuit constituting the RDC 100. However, the data are not transmitted to the host system. Such processing is performed until the reproduction head reaches a position where the data stored in the sector the reproduction of which is instructed are reproduced.

摘要： PROBLEM TO BE SOLVED: To suppress the illegal copy of data stored in a data storage device with simple constitution. SOLUTION: A CPU 10 and an HDD controller 14 are connected by a bus 18, and the HDD controller 14 and a hard disk drive 19 are connected by a bus 22. The bus 22 has connection constitution where bit data outputted by an HDD controller 14-side as MSB is supplied to a connection end for inputting/ outputting LSB of a hard disk drive 19-side. Thus, it is recorded in the hard disk drive 19 as that of a bit string in an order different from the order of the bit string of original data.
