摘要： According to one embodiment, a write instructing unit instructs a data access unit to write, in a storage area of a data storage unit indicated by a first physical address, write object data, instructs a management information access unit to update address conversion information, and instructs a first access unit to update the first physical address. A compaction unit extracts a physical address of compaction object data, instructs the data access unit to read the compaction object data stored in a storage area of the data storage unit indicated by the physical address, instructs the data access unit to write the compaction object data in a storage area of the data storage unit indicated by a second physical address, instructs the management information access unit to update the address conversion information, and instructs a second access unit to update the second physical address.

摘要： A high availability system includes a first server computer for a first virtual computer and a first hypervisor and a second server computer for a second virtual computer and a second hypervisor. The first virtual computer executes a processing and the second virtual computer executes the processing behind from the first virtual computer. Information associated with an event is transmitted. The event provides an input to the first virtual computer. In the second hypervisor, a control unit performs, control based on the information to match the execution state of the second virtual computer and that of the first virtual computer, and control associated with the information, when the event associated with the information is predetermined one of an I/O completion interrupt from the first virtual storage and an interrupt handler call corresponding to the interrupt, after the interrupt from the second virtual storage corresponding to the interrupt is caught.

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.

摘要： A size storage unit stores therein a block size of a memory element. A buffering unit executes buffer processing configured to store data received from a RAID (Redundant Arrays of Inexpensive/Independent Disks) controller into a buffer, and to write the data stored in the buffer into the memory element. A stripe-size receiving unit receives a stripe size that indicates a size of a unit of access at time of access to the memory element by the RAID controller. Writing processing is configured to write data received from the RAID controller into the memory element without executing the buffer processing by the buffering unit, when the stripe size is n times of the block size (n is a positive integer).
