Claims
- 1. A data storage gateway capable of interfacing with and providing connectivity and mapping between a Fiber Channel and SCSI channel interface, the data storage gateway comprising:a virtual storage; a storage router in communication with and providing mapping to the virtual storage such that a fiber channel device remote from the virtual storage can communicate data to and from the virtual storage; and wherein the storage router is capable of configuring a SCSI device to contain at least a portion of the virtual storage.
- 2. The data storage gateway according to claim 1, further including a memory work space for the storage router using a buffer.
- 3. The data storage gateway according to claim 2 wherein a Fibre Channel transport medium connects to the storage router and interfaces with a Fibre Channel controller and wherein a SCSI bus transport medium connects to the storage router and interfaces with a SCSI controller.
- 4. A method for providing, through a storage router, virtual local storage on remote SCSI storage devices to Fibre Channel devices, comprising:interfacing with a Fibre Channel transport medium; interfacing with a SCSI bus transport medium; maintaining a configuration for SCSI storage devices connected to the SCSI bus transport medium that maps between Fibre Channel devices and the SCSI storage devices and that implements access controls for storage space on the SCSI storage devices; and allowing access from Fibre Channel initiator devices to SCSI storage devices using native low level, block protocol in accordance with the configuration.
- 5. The method of claim 4, further comprising the step of providing memory work space for the storage router using a buffer.
- 6. The method of claim 5, wherein the Fibre Channel transport medium connects to and interfaces with a Fibre Channel controller and wherein said SCSI bus transport medium connects to and interfaces with a SCSI controller.
- 7. The method of claim 5, wherein the maintaining step and the allowing step are performed by a supervisor unit.
- 8. The method of claim 7, wherein the supervisor unit is coupled to the Fibre Channel controller, the SCSI controller, and the buffer.
