摘要： A storage system and method are provided including physical storage devices controlled by storage control devices constituting a storage control layer operatively coupled to the physical storage devices and hosts. The storage control layer includes: a first virtual layer interfacing with the hosts, operable to represent a logical address space characterized by logical block addresses, characterized by an Internal Virtual Address Space (IVAS) and operable, responsive to I/O requests addressed to logical block addresses, to provide protocol-dependent translation of said logical block addresses into IVAS addresses; and a second virtual layer interfacing with the physical storage space, and operable to represent available physical space to said hosts and characterized by a Physical Virtual Address Space (PVAS). Each address in PVAS having a corresponding address in IVAS. The second virtual layer is operable to translate PVAS addresses corresponding to IVAS addresses into addresses in physical address space in a protocol-independent manner.

摘要： A method is provided for performing arbitration in an information packet controller. The method includes transmitting different types of information packets from an initiator to a receiver. One type of information packet has a quality of service requiring a faster transmission time from the initiator to the receiver than another type of information packet having a quality of service having a slower transmission time from the initiator to the receiver. The transmitting of the information packets from the initiator to the receiver is in accordance with priority assigned to the information packet, the quality of service assigned to the information packet, and the age of such information packets having been stored in a queue of the initiator, such quality of service being a function of the speed at which the packets are required to pass from the initiator to a receiver.

摘要： Methods and systems are disclosed that relate to scheduling the processing of I/O requests in a cache for a plurality of logical devices associated with the cache. An exemplary method includes identifying a minimum target number of write destages to be performed with respect to a logical device per unit time. In identifying the minimum target number, factors such as a write pending count and an average queue length of writes pending may be considered. The method further includes enforcing the target minimum number of write destages. A disclosed method of enforcing the target includes tracking the number of write destages performed on the logical device and increasing a priority for a write request to the logical device when the minimum target number of write destages is not met.

摘要： Described are techniques and criteria used in connection with cache management. The cache may be organized as a plurality of memory banks in which each memory bank includes a plurality of slots. Each memory bank has an associate control slot that includes groups of extents of tags. Each cache slot has a corresponding tag that includes a bit value indicating the availability of the associated cache slot, and a time stamp indicating the last time the data in the slot was used. The cache may be shared by multiple processors. Exclusive access of the cache slots is implemented using an atomic compare and swap instruction. The time stamp of slots in the cache may be adjusted to indicate ages of slots affecting the amount of time a particular portion of data remains in the cache.

摘要： A method for managing read requests, the method may include receiving from a requesting entity a read request for reading an information unit stored in a storage system; determining by a control entity of the storage system whether the information unit is cached in a cache memory of the storage system and whether at least a predetermined number of disk drives of the storage system are currently overloaded; introducing a delay to a response to the read request thereby increasing a time difference between a time of the receiving of the read request and a time of a provision of the information unit to the requesting entity, if it is determined that the information unit is not cached in the cache memory and that the at least predetermined number of disk drives of the storage system are currently overloaded; and providing the information unit to the requesting entity.
