232 Stacking
Dell EMC Networking N1124T-ON/N1148T-ON switches and N1500 Series
switches support high-performance stacking over the 10G front-panel ports,
allowing increased capacity to be added as needed, without affecting network
performance and providing a single point of management. Up to four Dell
EMC Networking N1124T-ON/N1148T-ON switches and N1500 Series
switches can be stacked using any 10G port as long as the link bandwidth for
parallel stacking links is the same. Note that configuring a 10G port for
stacking also configures the adjacent partner 10G port for stacking.
A stack of four Dell EMC Networking N1124T-ON/N1148T-ON switches and
N1500 Series switches has an aggregate throughput capacity of 192 Gbps.
Dell EMC Networking N1124T-ON/N1148T-ON and N1500 Series stacking
links operate at 10 Gbps or 5.2% of total aggregate throughput capacity of a
full stack; therefore, it is recommended that operators provision large stacking
topologies such that it is unlikely that a significant portion of the stack
capacity will transit stacking links. One technique for achieving this is to
distribute uplinks evenly across the stack vs. connecting all uplinks to a single
stack unit or to adjacent stacking units.
A stack of twelve 48-port Dell EMC Networking N2000, N2100-ON, N3000,
or N3100-ON Series switches has an aggregate throughput capacity of
576 Gbps. Dell EMC Networking N2000/N2100-ON/N3000/N3100-ON
Series stacking links operate at 21 Gbps or 3.6% of total aggregate throughput
capacity of a full stack; therefore, it is recommended that operators provision
large stacking topologies such that it is unlikely that a significant portion of
the stack capacity will transit stacking links. One technique for achieving this
is to distribute uplinks evenly across the stack vs. connecting all uplinks to a
single stack unit or to adjacent stacking units.
Dell EMC Networking N2100-ON Series switches have two fixed stacking
ports in the rear that accept mini-SAS cables. Dell EMC Networking
N3100-ON Series switches support an optional 2x21G stacking module in the
rear slot.
Dell EMC Networking N4000 Series switches support high performance
stacking over front-panel ports, allowing increased capacity to be added as
needed, without affecting network performance and providing a single point
of management. Up to twelve Dell EMC Networking N4000 Series switches
can be stacked using any port as long as the link bandwidth for parallel
stacking links is the same. In other words, all the port types on the Dell EMC
Networking N4000 Series switches can be used for stacking. Additional
