IEEE Standard for Scalable Storage Interface
New IEEE Standard - Inactive-Reserved.
This document specifies a scalable interface between mass-storage devices and controlling hardware/software.
The interface has been optimized for low-latency interconnects, assuming that the processor/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):
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.
