    摘要: A server device is formed by a plurality of network interface processors connected to a network, each network interface processor having a network interface local memory functioning as a cache memory for storing a part of server data and a network interface local processor, at least one storage interface processor connected with a storage device for storing the server data, and a connection network for connecting the network interface processors and the storage interface processor. In this server device, the network interface local processor of one network interface processor carries out a control processing such that a requested data stored In the network interface local memory of the one network Interface processor is transmitted to the network when a request received from the network at the one network interface processor satisfies a prescribed first condition, and the request is given to the storage interface processor via the connection network when the request satisfies a prescribed second condition and the requested data is transmitted to the network upon receiving the requested data returned from the storage interface processor to the one network interface processor via the connection network in response to the request.

    摘要: A controller stores therein a sector address set indicating logical storage positions within a nonvolatile-memory storage area; page addresses indicating, in units of pages, physical storage positions within the nonvolatile-memory storage area; and pieces of management information each indicating whether one or more special sectors each being either a bad sector or a trimmed sector trimmed by a TRIM command are present in the corresponding page, while associating them with each other. When an access to a specified sector address is requested, the device refers to the piece of management information and judges whether any special sector is present in the page identified by the page address corresponding to the sector address. The device generates predetermined response data if the page contains one or more special sectors and accesses the nonvolatile-memory storage position corresponding to the sector address if the page contains no special sector.

    摘要: According to an embodiment, a memory system includes semiconductor memories each having a plurality of blocks; a first table; a receiving unit; a generating unit; a second table; and a writing unit. The first table includes a plurality of memory areas each associated with each block and in each of which defect information is stored. The generating unit generates a set of blocks by selecting one block to which data are to be written in each semiconductor memory based on an index number indicating one of a plurality of rows in the first table and the first table. In the second table, an index number and a channel number are stored for each logical block address in association with one another. When a write command is received by the receiving unit, the writing unit writes data to a block associated with a selected channel number among blocks constituting the set.

    摘要: According to an embodiment of a controller, a bit string manipulating unit manipulates a bit string of manipulation target data based on a predetermined rule. A special data setting unit generates a magic number based on a special data setting request from a host interface, obtains an error detecting code for the magic number, and sends the magic number and the error detecting code as manipulation target data to the bit string manipulating unit to obtain a manipulated manipulation target data. The special data setting unit also extracts logical block address information from the special data setting request, and instructs an access unit to write the magic number in the manipulated manipulation target data to a user data storage area and to write the error detecting code in the manipulated manipulation target data to a redundant area in a storage area located by the logical block address information.

    摘要: When data in one semiconductor memory device is corrupted during a padding process by a padding unit and the data cannot be recovered even by using an error correcting code for correcting a data error, a storage control device issues a data recovery request to a data recovery device. The data recovery device reads the data from other semiconductor memory device in response to the data recovery request to recover the data, and returns a recovery result to the padding unit in the storage control device to perform the padding process.
