Abstract:

A data center network architecture and method for communicating data are provided. The nodes and communication links in the network are arranged according to N dimensions. Groups of four nodes are arranged initially in quad full mesh networks. In each dimension, each node has three connections to other nodes. In particular, in each dimension, the nodes can be arranged in quarters, where a node in one quarter is connected to a node in each of three other quarters. In each dimension, the maximum number of hops between a sending node and a destination node is N. Due to the dimensionality, the nodes and communication links can be easily classified into different service levels, and diagnosis of problems is facilitated.

Abstract:

A method performed by a switch, the method comprising receiving a request for a file from a client, wherein the file is located in a distributed storage system, extracting a directory for the file from the request, performing longest prefix matching (LPM) of the directory against a forwarding information base (FIB) to identify a port, wherein the FIB associates directories with ports of the switch, and forwarding the client request toward a server containing the file via the identified port, wherein the server is one of a plurality of servers in the distributed storage system.
