    摘要： A system and method for optimizing lun masking of a storage appliance is provided. Upon login, an initiator data structure containing a lun map is created and associated with each initiator connected to the storage system. When an initiator sends a message directed to a lun associated with the storage system, the storage system maps the lun sent by the initiator to a physical lun associated with the storage system using the lun map. If the lun map contains an appropriate entry, then the lun has been successfully exported and/or masked to the given initiator.

    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.

    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.
