The storage controllercalculates an ideal utilizationfor each user, from the storage cost coefficientsand the user cost distribution information, and allocates, for each user, the ideal utilizationto each of the storage apparatusesand, in the order of the performance capabilities from highest to lowest.

Storage system and utilization management method for storage system

A computer includes first and second processors, first and second I/O devices, a shared memory, and an interrupt controller. The first processor issues a control command for causing the first I/O device to read target data from the first apparatus and store the target data in the shared memory. The first I/O device reads the target data from the first apparatus and, transfers the target data to the shared memory, and generates an I/O complete interrupt. The interrupt controller delivers the generated I/O complete interrupt to the second processor. When the second processor receives the I/O complete interrupt, the second processor issues a control command for causing the second I/O device to read the target data from the shared memory and send the target data to the second apparatus. The second I/O device reads the target data from the shared memory and sends the target data to the second apparatus.

Computer, computer system, and data communication method

An aspect of the invention is a storage control apparatus, comprising a plurality of processors, a memory, an I/O device coupled to a storage device, a virtualization module that allocates a first processor to a first guest and a second processor to a second guest from among the plurality of processors, and an interrupt control module that receives an interrupt from the I/O device and transmits the interrupt to any one of the plurality of processors, wherein the virtualization module comprises, a state detection module that detects at least one of a state of the first guest and a state of the first processor, and an interrupt delivery destination control module that switches the interrupt with respect to the first processor to the second processor when at least one of the state of the first guest and the state of the first processor becomes a predetermined state.

A storage system of the present invention improves the response performance of sequential access to data, the data arrangement of which is expected to be sequential. Data to be transmitted via streaming delivery is stored in a storage section. A host sends data read out from the storage section to respective user machines. A prefetch section reads out from the storage section ahead of time the data to be read out by the host, and stores it in a cache memory. A fragmentation detector detects the extent of fragmentation of the data arrangement in accordance with the cache hit rate. The greater the extent of the fragmentation, the smaller the prefetch quantity calculated by a prefetch quantity calculator. A prefetch operation controller halts a prefetch operation when the extent of data arrangement fragmentation is great, and restarts a prefetch operation when the extent of fragmentation decreases.
