摘要： In storage subsystems, due to the significant increase in HDD capacity, the time for executing online verification is elongated, affecting accesses from the host computer. By comprehending the status of accesses to the HDD, the sections where error has occurred and the status of restoration thereof, it becomes possible to detect defective or error sections efficiently at an early stage, according to which the reliability and access performance of the storage subsystem can be improved. The present storage subsystem executes one or more of the following processes: (M1) intensive verification of a circumference of an error LBA, (M2) an area-based prioritized verification, and (M3) continuous verification performed for a long period of time to (V1) an area in which error has occurred via IO access, (V2) a highly accessed area, and (V3) during a period of time when IO access is low.

摘要： A storage apparatus and response time control method capable of preventing response performance deterioration effectively are suggested. Since a response time control unit which delays a response of a corresponding storage device to a command and transfers it to a controller for a storage apparatus is located between the controller and part of or all storage devices in order to equalize response time for the plurality of storage devices to respond to a command issued from the controller, it is possible to equalize the response time of the plurality of storage devices and thereby effectively prevent deterioration of the response performance of the storage apparatus.
摘要翻译： 建议能够有效地防止响应性能恶化的存储装置和响应时间控制方法。 由于将对应的存储装置的响应延迟到命令并将其传送到存储装置的控制器的响应时间控制单元位于控制器与部分或全部存储装置之间，以便使多个 存储装置响应于从控制器发出的命令，可以使多个存储装置的响应时间相等，从而有效地防止存储装置的响应性能的劣化。
