Reliable L2 uplink interconnect Using a reliable L2 (Ethernet level) connection through the uplinks to connect the ToR switches is an acceptable alternative to MC-LAG for PowerStore deployments. With a reliable L2 connection you can port-channel the uplinks on each physical switch, which requires creating two portchannels instead of one.

Reliable L2 uplink interconnect
Using a reliable L2 (Ethernet level) connection through the uplinks to connect the ToR switches is an acceptable alternative to
MC-LAG for PowerStore deployments.
With a reliable L2 connection you can port-channel the uplinks on each physical switch, which requires creating two port-
channels instead of one.

NOTE:
Port location for the reliable high speed uplinks may change depending on switch vendor or model.
Reliable L2 uplinks require redundant, high speed connections.
