Product Overview
The Cisco MDS 9100 Series Multilayer Fabric Switches provide an intelligent, cost-effective, and
small-profile switching platform for small- and medium-sized storage environments. The
Cisco MDS 9100 Series also provides full-feature capability with the Cisco MDS 9500 Series multilayer
directors for a transparent, end-to-end service delivery in large data-center core-edge deployments.
The Cisco MDS 9100 Series includes four fixed configuration fabric switches:
• The Cisco MDS 9134 Multilayer Fabric Switch is a 32-port 1-, 2-, and 4-Gbps autosensing Fibre
Channel and 2-port 10-Gbps switch.
• The Cisco MDS 9124 Multilayer Fabric Switch is a 24-port, 1-, 2-, and 4-Gbps autosensing Fibre
Channel port switch.
• The Cisco MDS 9140 is a 40-port Fibre Channel switch.
• The Cisco MDS 9120 is a 20-port Fibre Channel switch.
The Cisco MDS 9100 Series is packaged in compact 1-RU enclosures with redundant hot-swappable
power supplies. The Cisco MDS 9140 Switch and the Cisco MDS 9120 Switch also include two
hot-swappable fan modules. Management access is provided through 10/100 Ethernet and serial console
interfaces.

• High port density at 40, 32, 24, or 20 ports per 1 RU.
• Port interfaces that support field-replaceable, hot-swappable small form-factor pluggable (SFP)
transceivers.
• Redundant and hot-swappable power supplies for high availability.
• Hot-swappable fan modules in the Cisco MDS 9140 Switch, Cisco MDS 9134 Switch, and the
Cisco MDS 9120 Switch.
