Abstract
Data center rack systems are described. A data center rack system can include a rack having switches. A removable chassis can include an arrangement of interconnect such that a topology for a switch network can be implemented when the removable chassis is coupled with the switches.
Claims20
A data center rack system, comprising:
- a network rack housing a first switch having a port and a second switch having a port;
- a first removable chassis having a first port and a second port, the first removable chassis including a first arrangement of interconnect coupling the first port with the second port, the first port of the first removable chassis coupled with the port of the first switch, and the second port of the first removable chassis coupled with the port of the second switch implementing a portion of a first topology of a first switch network, wherein:
- the first removable chassis is configured to be interchangeable with a second removable chassis implementing a portion of a second topology of a second switch network, the first topology and the second topology being different types of topologies, such that replacing the first removable chassis with the second removable chassis replaces the first topology of the first switch network with the second topology of the second switch network;
- a type of the first topology is one of a Clos network, a butterfly network, a mesh network, or a tree network;
- and
- a type of the second topology is a different one of a Clos network, a butterfly network, a mesh network, or a tree network.

A system, comprising:
- a first rack including a first set of switches;
- a second rack including a second set of switches;
- and
- a first chassis having a first arrangement of interconnect coupled with the first set of switches and the second set of switches to implement a first topology of a first switch network, wherein the first chassis is configured to be interchangeable with a second chassis having a second arrangement of interconnect and when coupled with the first set of switches and the second set of switches implements a second topology of a second switch network using the first set of switches and the second set of switches, the first arrangement of interconnect being different than the second arrangement of interconnect, wherein:
- a type of the first topology is one of a Clos network, a butterfly network, a mesh network, or a tree network;
- and
- a type of the second topology is a different one of a Clos network, a butterfly network, a mesh network, or a tree network.
4 more elements
A method, comprising:
- placing in a rack a first removable chassis that implements a portion of a first topology of a first switch network and that is configured to couple switches within the rack in the first topology, wherein the first removable chassis is configured to be interchangeable with a second removable chassis implementing a portion of a second topology of a second switch network, the first topology and the second topology being different types of topologies, such that replacing the first removable chassis with the second removable chassis replaces the first topology of the first switch network with the second topology of the second switch network, a type of the first topology is one of a Clos network, a butterfly network, a mesh network, or a tree network, and a type of the second topology is a different one of a Clos network, a butterfly network, a mesh network, or a tree network;
- directing data among the switches within the rack based on the first topology;
- replacing the first removable chassis with the second removable chassis configured to couple the switches within the rack in the second topology;
- and
- directing data among the switches within the rack based on the second topology.
