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.
Port numbers are assigned depending on whether the physical ports are partitioned into data lanes. To
illustrate, Figure 92
for physical ports P1 through P8.
