The SAND™ chipset includes a Fabric Element device (FE200) and a family of Fabric Access Processor (FAP) devices. The FE200 enables switched-based systems across all types of FAP devices. The FAP devices differ from each other by the aggregate rate they provide to the user, their traffic-management capabilities, and the interface towards the NP or MAC/framer. The SAND chipset enables, for the first time, Internet and storage-platform vendors to build a full product line, using the same chipset guaranteeing a life cycle of 7+ years. In order to provide this extensive life cycle, the SAND chipset provides three scaling dimensions: port bandwidth, port count, and port service scheme. A system built using the SAND chipset is capable of providing total user bandwidth starting from 10Gbps and extending up to 80Tbps. The system allows the user to connect mixed rate line cards (10Gbps to 100Gbps) and line cards with various traffic management capabilities. The FAP21V device provides 20Gbps ingress/egress comprehensive traffic-management functionality via SPI4.2 interfaces while incorporating a switch fabric interface. The embedded switch fabric interface allows the FAP21V device to interconnect and FAP21V as Egress TM Line Card-1 MAC Framer (Egress) SPI 4.2 communicate via its fabric interface, allowing any system of any size to provide end-to-end rate and weight guarantees for packet flows. System Configurations and Applications The FAP21V can be used: • As a stand-alone traffic manager in a system based on a Combined-Input-Output-Queuing (CIOQ) architecture, which uses a third party fabric. In such a configuration the FAP device is used as ingress and/or as egress TM • In mesh configurations of FAP20V/FAP21V devices (up to 60G non-blocking systems) • In Dune fabric-based systems which may reach 40Tbps The versatility of the FAP21V device enables a vendor to design a full product line using the same chipset, sharing the same line and fabric cards. For example, for low-capacity platforms, the fabric-less (mesh) FAP configurations may be used, while the higher-capacity platforms may use the same line cards connected via fabric cards. Stand-alone Egress Traffic Manager The FAP21V device may be used as stand-alone egress traffic manager, connected directly to a MAC/Framer device as shown in the diagram below.

Such configurations are cost effective and provide 60Gbps non-blocking total system performance. SPI 4.2 B SPI 4.2 A SPI 4.2 B SPI 4.2 A SPI 4.2 B SPI 4.2 A In stand-alone mode, a FAP21V device provides comprehensive local traffic management services, such as deep buffering, congestion avoidance via WRED, fine-grained weight and rate-based flow shaping and hierarchical scheduling toward the egress port. A switched configuration constructed by several FAP21V devices connected via their fabric interface, enables end-to-end rate and weight guarantees of traffic flows across a complete system. In such a configuration a FAP21V device performs ingress and egress functions (scheduling and routing) to and from the switching fabric, in addition to providing complete traffic management functionality (shaping and queuing). Ingress shaping is a scheme for limiting and prioritizing the amount of data that a source can inject into t.
