Abstract
Methods, systems, and computer program product embodiments for controlling congestion in a storage grid, by a processor device, are provided. In a storage grid, a storage request transmit queue length of storage requests submitted by a plurality of nodes is monitored, the storage request transmit queue comprising a queue holding the storage requests unable to be transmitted through a current transmission control protocol/internet protocol (TCP/IP) socket buffer of the storage grid. Upon reaching at least one of a certain threshold, a watermarked message indicating a specific one of the plurality of nodes is congested is transmitted to upper layer grid nodes in a hierarchy of the plurality of nodes transmitting the storage requests, and the upper layer grid nodes each alter the storage requests based upon the watermarked message.
