The 2109 Model M12 represents the next generation of advanced Fibre Channel
switches that are used to intelligently interconnect storage devices, hosts, and
servers in a storage area network (SAN). It is a revolutionary product, a dual
64-port Fibre Channel switch that delivers unprecedented performance, scalability,
flexibility, functionality, reliability, and availability.
v The 2109 Model M12 delivers a very high-density port, rack-ready solution to
drive cost-effective SAN.
v The dual switch capability allows either one or two 64-port switches per chassis.
You can interconnect the switches to create a high port count solution, or you
can use them in a dual fabric, high availability topology.
v The 2109 Model M12 supports 1 Gbps and 2 Gbps auto-sensing Fibre Channel
ports. Trunking technology groups up to four ports together to create high
performance 8 Gbps inter-switch links (ISL) trunks between switches.
v Universal ports self-configure as expansion ports (E_ports), fabric ports (F_ports),
or fabric loop ports (FL_ports).
v Small form-factor pluggable (SFP) optical transceivers support any combination
of short wavelength (SWL) and long wavelength (LWL) optical media on a single
switch module.
v The 2109 Model M12 offers a high availability platform for mission-critical
SAN-designed applications.
v Dual redundant control processors (CPs) provide high availability and enable
nondisruptive software upgrades.
v The 2109 Model M12 offers forward and backward compatibility with all 3534 and
2109 series switches.
v The Fabric operating system (OS) delivers distributed intelligence throughout the
network and enables a wide range of value-added applications including
Extended Fabrics, Fabric Access, Fabric Watch, Remote Switch, Web Tools,
Secure Fabric OS, Advanced Zoning, and Advanced Security feature.
v High availability redundant design, extensive diagnostics, and system monitoring
capabilities integrated with Fabric OS management tools deliver unprecedented
reliability, availability, and serviceability.
