Offloading node CPU in distributed redundant storage systems

摘要

A network interface includes a host interface for communicating with a node, and circuitry which is configured to communicate with one or more other nodes over a communication network so as to carry out, jointly with one or more other nodes, a redundant storage operation that includes a redundancy calculation, including performing the redundancy calculation on behalf of the node.

主权项

1. A Network Interface Controller (NIC) that connects a compute node to a communication network, the NIC comprising:
a host interface, which is comprised in the NIC and which is configured for communicating with the compute node; communication circuitry, which is comprised in the NIC and is configured to communicate with one or more other nodes over the communication network so as to carry out, jointly with one or more other nodes, a redundant storage operation involving data; and offloading computation logic circuitry, which is comprised in the NIC and is configured to calculate redundancy information over at least part of the data of the redundant storage operation, while offloading a Central Processing Unit (CPU) of the compute node from calculating the redundancy information.
