摘要： Storage apparatus and data management methods provide for high-speed copying of a compressed data volume. A control unit of the storage apparatus divides a pool into a plurality of chunks including a plurality of pages storing data, compresses data which is written to a logical volume by a host, and assigns one of the plurality of chunks to a compressed data logical volume which stores the compressed data. When the compressed data logical volume is copied, the control unit makes a page length of the chunk assigned to the compressed data logical volume that is a copy source equivalent to a page length of the chunk assigned to the compressed data logical volume that is the copy destination.

摘要： An embodiment of this invention divides a cache memory of a storage system into a plurality of partitions and information in one or more of the partitions is composed of data different from user data and including control information. The storage system dynamically swaps data between an LU storing control information and a cache partition. Through this configuration, in a storage system having an upper limit in the capacity of the cache memory, a large amount of control information can be used while access performance to control information is kept.

摘要： With respect to a storage system in which quick formatting and sequential formatting can be run concurrently, the time it takes to process an access request from a host is prevented from becoming prolonged even when a normal sequential formatting process is executed with respect to a storage volume which frequently incurs I/O penalties. The storage device measures the load from the host per configurational unit (storage medium) of LUs, and divides the LUs into a group of LUs whose load per storage medium is low, and a group of LUs whose load per storage medium is high. Further, the density per unit of LU capacity of I/O penalties incurred in a storage volume for which quick formatting is being executed is calculated. Sequential formatting is then executed, with priority, with respect to the LUs belonging to the group with low loads and in order of descending density of incurred I/O penalties.

摘要： To extend endurance and reduce bit cost, a storage apparatus includes a controller and a first storage device and a second storage device having a smaller erase count upper limit than the first storage device. Area conversion information includes correspondence of a first address of a data storage destination and a second address of a data storage area The controller selects an area corresponding to the first address, determines whether a rewrite frequency of the selected area is equal to or larger than a first threshold and, when the rewrite frequency is equal to or larger than the threshold, selects an area of the first storage device, and, when the rewrite frequency is smaller than the threshold, selects an area of the second storage device and maps the address of the selected area to the first address.

摘要： In order to reduce erroneous ignition timing to the maximum possible degree, an arbitrary point is defined between the trailing edge of a basic control pulse and TDC. The ADV at which ignition should occur is determined to be advanced or retarded with respect to the same. If it is found that the ADV is advanced with respect to the arbitrary point where a calculation, which is initiated at the trailing edge of the basic control pulse cannot be completed in time, a time period from the leading edge is derived and a counter started. Alternatively, if a count is not proceeding and a trailing edge is detected, a second time is derived and the counter started. If it is found that the counter is running but the degree of ignition advance is such as to fall between the leading and trailing edges of the basic reference control pulse, the count is stopped and ignition immediately induced.

摘要： An air/fuel ratio control system is designed for detecting small deceleration and subsequently detecting small magnitude acceleration. When small magnitude acceleration is detected, a LAMBDA control correction value which is utilized for deriving fuel injection amount, is fixed at a predetermined value for a predetermined period. The air/fuel ratio utilized during the aforementioned period is set at a value greater than the instantaneous value at a timing at which a demand for small magnitude acceleration is detected.
