摘要： A method of resetting a stateful connection in a storage cluster with stateless load-balancing is provided. The method includes receiving a packet associated with a stateful connection between a client and a first storage node of the storage cluster. The method includes sending a reset packet from a second storage node to the client, through a stateless load balancer, responsive to the second storage node failing to recognize the packet associated with the stateful connection between the client and the first storage node, wherein the client resets the stateful connection responsive to receiving the reset packet. The method includes sending further reset packets from the load balancer to a plurality of storage nodes of the storage cluster, responsive to receiving, at the load balancer, the reset packet from the second storage node, wherein the plurality of storage nodes reset stateful connection information responsive to receiving the further reset packets.

摘要： A method for efficient data forwarding in a networked device is provided. The method includes receiving a first packet from a first VLAN into a load balancer of the networked device and forwarding the first packet from the load balancer to a second VLAN internal to the networked device, wherein an identity of the first VLAN is unknown as a result of forwarding the packet from the first VLAN to the second VLAN. The method includes determining the identity of the first VLAN, based on a source IP address of the first packet and a map of IP addresses and VLANs. The method includes sending a second packet from one of a plurality of nodes, in response to the receiving, with the source IP address of the first packet as a destination IP address of the second packet and with a field of the second packet identifying the first VLAN.
