Isolating clients of distributed storage systems

摘要

A distributed storage system that includes memory hosts. Each memory host includes non-transitory memory and a network interface controller in communication with the memory and servicing remote direct memory access requests from clients. The memory receives a data transfer rate from each client in communication with the memory host through remote direct memory access. Each memory host also includes a data processor in communication with the memory and the network interface controller. The data processor executes a host process that reads each received client data transfer rate, determines a throttle data transfer rate for each client, and writes each throttle data transfer rate to non-transitory memory accessible by the clients through remote direct memory access.

1. A distributed storage system comprising:
memory hosts, each memory host comprising:
non-transitory memory;a network interface controller in communication with the non-transitory memory and servicing remote direct memory access requests from clients, the non-transitory memory receives a data transfer rate from each client in communication with the memory host through remote direct memory access; anda data processor in communication with the non-transitory memory and the network interface controller, the data processor executing a host process that:
reads each received client data transfer rate;receives an isolation configuration providing a bandwidth capacity for the memory host and a list of bandwidth reservations for the clients, each bandwidth reservation reserving a threshold data transfer rate for a client;determines a throttle data transfer rate for each client based on the isolation configuration; andwrites each throttle data transfer rate to non-transitory memory accessible by the clients through remote direct memory access.
