Each Supervisor-2 Module provides the
necessary crossbar bandwidth to
deliver full system performance in the
Cisco MDS 9506 director with up to
four Fibre Channel switching modules.
It is designed to eliminate the impact on
system performance of the loss or
removal of a single crossbar module.
Connectivity, compatibility and traffic
management
The Cisco MDS 9506 for IBM System
Storage requires a minimum of one and
allows a maximum of four switching
modules. These modules are available
in either a 12-port 4 Gbps or 24- and
48-port 4 and 8 Gbps configurations,
allowing the Cisco MDS 9506 to sup-
port 12 to 192 Fibre Channel ports per
chassis. Optionally, a 4-port 10 Gbps
Fibre Channel module is available for
high-performance Inter-Switch Link
(ISL) connections over metro optical
networks.
Switching modules are hot-swappable
with small form-factor pluggable (SFP)
optic transceivers and support LC inter-
faces. The PortChannel capability
allows users to aggregate up to
16 physical Inter-Switch Links into a
single logical bundle, providing opti-
mized bandwidth utilization across all
links.
12-, 24- and 48-port 4 Gbps switching
modules: Configuring the switch for the
application environment
The 12-port 4 Gbps Fibre Channel
Switching Module is designed to
deliver high performance for the most
demanding storage networking applica-
tions. Autosensing 1, 2 and 4 Gbps
ports deliver up 96 Gbps of continuous
aggregate bandwidth, which provides
up to 8 Gbps throughput per port
(full-duplex). The 12-port switching
module is well suited for attaching
highest-performance 4 Gbps enabled
servers and storage subsystems as well
as to connect to other switches using
4 Gbps ISL connections.
The 24-port 4 Gbps Fibre Channel
Switching Module is designed for
high-performance storage networking
applications. Twenty-four autosensing
1, 2 and 4 Gbps ports are designed
deliver sustained bandwidth required to
meet the performance requirements of
enterprise-class storage and servers.
Port bandwidth reservation enables
1, 2 or 4 Gbps switching bandwidth to
be dedicated to a port, including high-
est performance ISL ports. The 24-port
switching module is well suited for
attaching high-performance servers and
storage subsystems as well as for con-
necting to other switches using ISL
connections.
The 48-port 4 Gbps Fibre Channel
Switching Module is designed to
deliver an optimal balance of perform-
ance and port density. Forty-eight
autosensing 1, 2 and 4 Gbps ports are
designed deliver sustained bandwidth
required to meet a wide range perform-
ance requirements for a mixture of SMB
and enterprise-class storage and
servers. Port bandwidth reservation
enables 1, 2 or 4 Gbps switching band-
width to be flexibly dedicated to ports
to meet a wide range of application
requirements. This module is designed
to provide a low-cost means of attach-
ing lower performance servers and
storage subsystems to the high-
performance crossbar switch fabric
without requiring ISLs.
24-, 48- and 4/44-port 8 Gbps switching
modules: Configuring the switch for fast
link speeds
The 24-port 8 Gbps Fibre Channel
Switching Module is designed for
uncompromising performance of up to
96 Gbps of continuous aggregate
