US 11,689,610 B2 · Load balancing reset packets

Abstract

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.

Dependent claims

A method, comprising:

transmitting a first plurality of reset packets from a first stateless load balancer to a plurality of second stateless load balancers, wherein the first stateless load balancer is configurable to load balance across a plurality of chassis, and wherein each chassis has a subset of storage nodes of a storage cluster;
and
transmitting a second plurality of reset packets from each of the plurality of second stateless load balancers to the subset of storage nodes associated with a second load balancer, responsive to receiving one of the first plurality of reset packets at each second stateless load balancer, wherein the second stateless load balancer is configurable to load balance across the subset of storage nodes.
