Locking technique for control and synchronization

摘要: Described are techniques used in a computer system for handling data operations to storage devices. A switching fabric includes one or more fast paths lightweight, common and at least control path other operations. manages paths. The the utilized mapping virtual physical addresses using tables. tables include an extent table of entries corresponding varying address ranges. size may be changed dynamically accordance with state change storage. cache only portions as needed caching technique. subset stored within path. set primitives performing locking mechanism is described controlling access shared by
