This standard defines a scalable interface for use with memory-mapped storage units and other devices. The term “storage unit” can encompass rotating, non-rotating, volatile and non-volatile storage. Issues of concurrency, latency, bandwidth, extensibility, and negotiation will be addressed. The interface is intended for use with either a single storage unit or with many coordinated storage units.
This standard provides an efficient physical-layer independent interface architecture for storage units that attach directly to memory access buses. In this interface model, storage units have an attachment to main memory, rather than an attachment to an I/O channel. This simplifies the storage unit design and supports scheduling of data transfers spanning large numbers of units.
New IEEE Standard – Inactive-Reserved. This document specifies a scalable interface between mass-storage devices and controlling hard-ware/software. The interface has been optimized for low-latency interconnects, assuming that the proces-sor/controller and the storage device can often be co-located on the same printed-circuit board. The interface can also be used with longer-distance bus-like interconnects, including (but not limited to) IEEE Std 1394-1995 Serial Bus and IEEE Std 1596-1992 Scalable Coherent Interface.
