A Small Computer System Interface (SCSI) transport for fabric backplane
enterprise servers provides for local and remote communication of storage
system information between storage sub-system elements of an ES system
and other elements of an ES system via a storage interface. The transport
includes encapsulation of information for communication via a reliable
transport implemented in part across a cellifying switch fabric. The
transport may optionally include communication via Ethernet frames over
any of a local network or the Internet. Remote Direct Memory Access
(RDMA) and Direct Data Placement (DDP) protocols are used to communicate
the information (commands, responses, and data) between SCSI initiator
and target end-points. A Fibre Channel Module (FCM) may be operated as a
SCSI target providing a storage interface to any of a Processor Memory
Module (PMM), a System Control Module (SCM), and an OffLoad Module (OLM)
operated as a SCSI initiator.
