Abstract
An example system including a first top-of-rack (ToR) switch, and a second ToR switch, the second ToR switch is to receive a network packet from a first host, the network packet to include a destination address of a second host, and after a failure of a physical network interface card (pNIC) at the second host eliminates a first link between the second host and the second ToR switch, send the network packet to the first ToR switch via an inter-switch link between the first and second ToR switches to cause the first ToR switch to forward the network packet to the second host via a second link between the first ToR switch and the second host.
Claims20
A system comprising:
- a first top-of-rack (ToR) switch;
- and
- a second ToR switch, the second ToR switch to:
- receive a network packet from a first host, the network packet to include a destination address of a second host;
- and
- after a failure of a physical network interface card (pNIC) at the second host eliminates a first link between the second host and the second ToR switch, send the network packet to the first ToR switch via an inter-switch link between the first and second ToR switches to cause the first ToR switch to forward the network packet to the second host via a second link between the first ToR switch and the second host.
A non-transitory machine readable storage medium comprising instructions to cause a first top-of-rack (ToR) switch to at least:
- access a network packet from a first host, the network packet to include a destination address of a second host;
- and
- after a failed physical network interface card (pNIC) at the second host eliminates a first link between the second host and the first ToR switch, send the network packet to a second ToR switch via an inter-switch link between the first and second ToR switches to cause the second ToR switch to forward the network packet to the second host via a second link between the second ToR switch and the second host.
A method comprising:
- receiving a network packet at a first top-of-rack (ToR) switch from a first host, the network packet including a destination address of a second host;
- and
- after a failure of a physical network interface card (pNIC) at the second host eliminates a first link between the second host and the first ToR switch, sending the network packet to a second ToR switch via an inter-switch link between the first and second ToR switches to cause the second ToR switch to forward the network packet to the second host via a second link between the second ToR switch and the second host.
