Abstract

Storage gateway remote and local access to storage devices is provided in part via an initiator implementing bandwidth-controlled access to the devices. The initiator may be iSCSI-compatible, and may also optionally implement protection, security, and performance features. The protection and security features include any combination of VLANs, zoning, Logical Unit Number (LUN) masking, and encryption. The performance features include any combination of HW-accelerated Remote Direct Memory Access (RDMA), prioritized I/O operations, and service priority (such as strict priority and straight or weighted round-robin priorities). An initiator may be implemented in a Processor Memory Module (PMM) coupled to a switch fabric that is in turn coupled to a target implemented in a Fibre Channel Module (FCM). Storage traffic may be communicated as Small Computer System Interface (SCSI)- and SCSI over Transmission Control Protocol/Internet Protocol (iSCSI)-compatible information (data and commands) on the switch fabric via cellifying input/output interface devices.
