SAND Overview
Dune Networks SAND™ (Scalable Architecture for
Networking Devices) chipset provides a complete
solution for switching fabric and ingress/egress
traffic management. 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
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.
