摘要： A system and method enabling transparent access to blocks, such as virtual disks, stored on a storage system using a file-based protocol. The system and method traps in-coming file-based protocol open commands to check for a predetermined modification to the file name. If the system and method detects the predetermined modification, then the virtual disk associated with the file name is exported to the client issuing the open command and the client receives a response from the storage system. The client, in response to receiving the response to the open command, creates a new device instantiation for reading and writing raw data to the virtual disk.

摘要： A system integrates an intelligent storage switch with a flexible virtualization system to enable the intelligent storage switch to provide efficient service of file and block protocol data access requests for information stored on the system. A storage operating system executing on a storage system coupled to the switch implements the virtualization system to provide a unified view of storage to clients by logically organizing the information as named files, directories and logical unit numbers. The virtualization system may be embodied as a file system having a write allocator configured to provide a flexible block numbering policy to the storage switch that addresses volume management capabilities, such as storage virtualization.

摘要： A system integrates an intelligent storage switch with a flexible virtualization system to enable efficient service of file and block protocol data access requests for information stored on the system. A storage operating system executing on a storage system coupled to the switch implements the virtualization system to provide a unified view of storage to clients by logically organizing the information as named files, directories and logical unit numbers. The virtualization system is illustratively embodied as a file system having a write allocator configured to provide a flexible block numbering policy that addresses volume management capabilities, such as storage virtualization, at a finer granularity (e.g., a single block) than that of previous non-flexible storage virtualization schemes. The flexible block numbering policy also yields substantial benefits in terms of increased write efficiency and elimination of storage “hot spots”, as well as a compelling point-in-time read-only data image (snapshot) mechanism.

摘要： A system and method provides a remote direct memory access over a transport medium that does not natively support remote direct memory access operations. An emulated VI module of a storage operating system emulates RDMA operations over such a medium, e.g., conventional Ethernet, thereby enabling storage. Storage appliances in a cluster configuration utilize the non-RDMA compatible transport medium as a cluster interconnect.

The mechanism expands a file access protocol, such as the direct access file system protocol, by including a hurry up command that adjusts the latency of a given input/output operation. The hurry up command can be employed in the Direct Access File System.

摘要： A technique enhances a write data path within a storage operating system executing on a storage system. As used herein, the write data path defines program logic used by a file system of the storage operating system to process write requests directed to data served by the file system. The technique enhances the write data path of the storage system by providing a “zero copy” write data path embodied as a function of the storage operating system that eliminates a copy operation for a write request received at the storage system. The eliminated operation is a data copy operation from a list of input buffers to buffers used by the file system.
