Patent ID: 11997024

Abstract:
A network infrastructure device (e.g., network switch), that integrates solid-state drive (SSD) storage, using Non-volatile Memory Express (NVMe) data transfer protocol, for use by remote application hosts is provided. High availability configurations of network switches using direct rate control (RC) feedback for a plurality of submission queues mapped to SSD storage is provided. NVMe over fabric (NVMe-oF) is an implementation of NVMe protocol over a network fabric. Access to SSDs over network fabrics may be controlled using a direct RC feedback signal between an egress queue congestion accounting (associated with a single egress output) and a source node receiving input/output commands from remote hosts for the integrated SSD devices. In some implementations, direct RC feedback signals use hardware based signals. In some implementations, direct RC feedback signals are implemented in the hardware logic (silicon chip logic) within an internal switch fabric of the network switch.
