The 2109 Model F16 switch provides the following features:

16 nonblocking ports that provide full-duplex, throughput bandwidth at either
1.0625 Gbps or 2.125 Gbps

Fibre Channel auto-sensing ports that self-negotiate to the highest speed that is
supported by the attached devices

Universal ports that self-configure as fabric ports (F_ports), fabric loop ports
(FL_ports), or expansion ports (E_ports)

Trunking, which allows you to group up to four ports to create high-performance
8 Gbps inter-switch link (ISLs) between switches

Hardware zoning that permits or denies delivery of frames to any particular
destination port address

Frame filtering, which augments the hardware zoning capabilities of the
second-generation ASIC. The second-generation ASIC implements hardware
zoning at the port level of the switch. The expanded capabilities of the
third-generation ASICs include world wide name (WWN), device-level zoning,
protocol-level zoning, and logical unit number (LUN)-level zoning to provide the
flexibility of second generation software zoning with the enhanced security of
hardware zoning.

Note:

You will need Fabric OS version 3.1 for protocol-level and LUN-level
zoning support.

Phantom loop addressing that allows private 8-bit loop addresses to be treated
as equivalent to public loop addresses

Support for unicast, multicast (up to 256 groups), and broadcast data traffic types

Extensive diagnostics, system-monitoring capabilities, and dual redundant,
hot-swappable power supplies and cooling units that provide high reliability,
availability, and serviceability

A single system board design with a 100 MHz 80960VH reduced instruction-set
computer (RISC) central processing unit (CPU) with integrated peripherals that
provide high performance

Small form-factor pluggable (SFP) media that supports short wavelength (SWL)
optical, and long wavelength (LWL) optical

Fabric Operating System (OS) that delivers distributed intelligence throughout the
network and enables a wide range of applications

A flexible topology that allows the interconnection of up to 239 switches to create
a medium to large Fibre Channel fabric. The topology can change dynamically as
you add new switches or links to the fabric or as your needs change.

Central memory architecture that maximizes switch throughput, guarantees full
transmit and receive bandwidth to all Fibre Channel ports at all times, and
enables a number of sophisticated queuing, messaging, and buffer pool
management schemes to optimize switch performance characteristics in heavily
loaded systems

Cut-through frame routing that minimizes port-to-port latency

Hardware components

The 2109 Model F16 system board is a single-board design with a highly integrated
CPU. The Intel

80960VH CPU is a RISC core processor and is the top choice for

this platform. It provides over 70% of the functionality for the digital section of the
system board. The system uses three types of memory devices: DRAM, Flash File,
and Boot Flash. On the Fibre Channel section of the system board, the Bloom
