ExtremeSwitching X870 Series Switches
The X870 series switch is a 100 Gb switch suited for large datacenter applications. Front-panel Ethernet
ports can provide 100-gigabit Ethernet connectivity using installable QSFP28 and QSFP+ optical
modules. The ports can operate in 40- or 100-gigabit mode and can be partitioned into 10-, 25-, and 50-
gigabit data lanes. (See
example.)
The X870 provides latency less than 600 nanoseconds and supports cut-through switching to help
optimize high frequency trading applications as well as latency sensitive cluster computing.
Native stacking with other X870 series switches is supported using the front panel-ports.
The X870 series includes the following base models:
•
ExtremeSwitching X870-32c Switch Ports and Slots
•
ExtremeSwitching X870-96x-8c Switch Ports and Slots
X870 series switches require ExtremeXOS version 22.2.1 or later.

Partitioning X870 Switch Ports into Data Lanes

Front-panel ports on X870 series switches can be configured for either 100-gigabit or 40-gigabit mode,
and each port can be partitioned into data lanes through the use of split cables. This yields a total of up
to 128 ports.
