摘要:
A control method is disclosed for a storage control apparatus having a plurality of channel control units connected to communicate with each other and which receives a data input or data output request transmitted from an information processing device and controls writing and reading of data to a storage device in accordance with the data input/output request, and a disk control unit which carries out the writing and reading of data to the storage device in accordance with the control signal. A first channel control unit monitors the information processing device by communicating with the information processing device. When a problem is detected in the information processing device, the channel control unit restricts processing to be carried out in accordance with the data input/output request by a second channel control unit to which the data input/output transmitted from the information processing device is delivered.
摘要:
A storage device controlling apparatus includes: a plurality of channel controllers having a circuit board on which are formed a file access processing section receiving requests to input and output data in files as units from an information processing apparatus and an I/O processor outputting I/O requests corresponding to the requests to input and output data to a storage device; and a disk controller executing input and output of data into and from the storage device in response to the I/O requests sent from the I/O processors. In the storage device controlling apparatus, the disk controller performs a replication management processing whereby data is also written into a second logical volume to store a copy of the data in the second logical volume, when the data is written into a first logical volume.
摘要:
A disk array system includes storage devices, a storage device control unit, a connection unit being connected with the storage device control unit, channel control units, a shared memory, and a cache memory. Each channel control unit includes a first processor of converting file data, received through a local area network outside of the disk array system to which the channel control units belongs, into block data and requesting storage of the converted data in the plurality of storage devices and a second processor of transferring the block data to the storage devices through the connection unit and the storage device control unit in response to a request given from the first processor and is connected with the connection unit and the local area network.
