Are data center switches non blocking? Is it an important feature in a data center switch?
For example, Cisco Nexus C36180YC-R,
It has got:
- Switching capacity: 3.6 Tbps (48x25+6x100=1800 Gbps half duplex x2)
- Forwarding Rate: 1.67 Bpps
I calculate the forwarding rate as 1800x1.5= 2700 Mpps= 2.7Bpps, so I understand this switch is not Non-blocking, so it has got oversubscription in its ports
It is the same with HP 8325-48Y8C or Huawei CloudEngine 6865-48S8CQ-EI.
