The Cisco UCS 6100 Series is equipped to support the following module options:
●
Ethernet module that provides 6 ports of 10 Gigabit Ethernet using the SFP+ interface
●
Fibre Channel plus Ethernet module that provides 4 ports of 10 Gigabit Ethernet using the SFP+ interface;
and 4 ports of 1/2/4-Gbps native Fibre Channel connectivity using the SFP interface
●
Fibre Channel module that provides 8 ports of 1/2/4-Gbps native Fibre Channel using the SFP interface for
transparent connectivity with existing Fibre Channel networks
●
Fibre Channel module that provides 6 ports of 1/2/4/8-Gbps native Fibre Channel using the SFP or SFP+
interface for transparent connectivity with existing Fibre Channel networks

3.2.2 Cisco UCS 2100 Series Fabric Extenders
The Cisco UCS 2100 Series Fabric Extenders bring the unified fabric into the blade server enclosure, providing
10 Gigabit Ethernet connections between blade servers and the fabric interconnect, simplifying diagnostics,
cabling, and management.
The Cisco UCS 2100 Series extends the I/O fabric between the Cisco UCS 6100 Series Fabric Interconnects and
the Cisco UCS 5100 Series Blade Server Chassis, enabling a lossless and deterministic FCoE fabric to connect
all blades and chassis together. Since the fabric extender is similar to a distributed line card, it does not do any
switching and is managed as an extension of the fabric interconnects. This approach removes switching from the
chassis, reducing overall infrastructure complexity and enabling the Cisco Unified Computing System to scale to
many chassis without multiplying the number of switches needed, reducing TCO and allowing all chassis to be
managed as a single, highly available management domain.
The Cisco 2100 Series also manages the chassis environment (the power supply and fans as well as the blades)
in conjunction with the fabric interconnect. Therefore, separate chassis management modules are not required.
The Cisco UCS 2100 Series Fabric Extenders fit into the back of the Cisco UCS 5100 Series chassis. Each Cisco
UCS 5100 Series chassis can support up to two fabric extenders, enabling increased capacity as well as
redundancy.
