Abstract: Described herein is a network fabric architecture for DRCC. The fabric includes a plurality of blocks of switches. A compute fabric (CFAB) block is provided that is communicatively coupled to the plurality of blocks of switches. The CFAB block includes: (i) a set of one or more racks, where each rack comprised one or more servers configured to execute one or more workloads of a customer, and (ii) a first plurality of switches organized into a first plurality of levels. The first plurality of switches is communicatively couples the set of one or more racks to the plurality of blocks of switches. A network fabric block is provided that is communicatively coupled to the plurality of blocks of switches and includes (i) one or more edge devices including a first edge device providing connectivity (to a workload) to a first external resource, and (ii) a second plurality of switches organized into a second plurality of levels.

Abstract: Disclosed herein is a method of providing fault domains within a rack. An availability domain comprising a rack is provided, where the rack comprising a plurality of top-of-rack (TOR) switches and a plurality of host machines. A first fault domain is created within the availability domain. The first fault domain comprised a first TOR switch from the plurality of TOR switches and a first subset of host machines from the plurality of host machines. The first subset of host machines is communicatively coupled to the first TOR. A second fault domain is created within the availability domain, where the second fault domain comprised a second TOR switch from the plurality of TOR switches and a second subset of host machines from the plurality of host machines. The second subset of host machines is communicatively coupled to the second TOR.

Abstract: A method for providing a dedicated region cloud at customer is provided. A first physical port of a network virtualization device (NVD) included in a datacenter is communicatively coupled to a first top-of-rack (TOR) switch and a second TOR switch. A second physical port of the NVD is communicatively coupled to a network interface card (NIC) associated with a host machine. The NVD receives a packet from the host machine via the second physical port of the NVD. The NVD further determines a particular TOR, from a group including the first TOR and the second TOR, for communicating the packet, and transmits the packet to the particular TOR to facilitate communication of the packet to a destination host machine.

Abstract: A method for providing a dedicated region cloud at customer is provided. A first physical port of a network virtualization device (NVD) included in a datacenter is communicatively coupled to a first top-of-rack (TOR) switch and a second TOR switch. A second physical port of the NVD is communicatively coupled with a network interface card (NIC) associated with a host machine. The second physical port provided a first logical port and a second logical port for communications between the NVD and the NIC. The NVD receives a packet from the host machine via the first logical port or the second logical port. Upon receiving the packet, the NVD determines a particular TOR, from a group including the first TOR and the second TOR, for communicating the packet. The NVD transmits the packet to the particular TOR to facilitate communication of the packet to a destination host machine.
