Abstract

Systems and methods that network interface are provided. In one embodiment, a data center may be provided that may include, for example, a first tier, a second tier and a third tier. The first tier may include, for example, a first server. The second tier may include, for example, a second server. The third tier may include, for example, a third server. At least one of the first server, the second server and the third server may handle a plurality of different traffic types over a single fabric.

Claims

1. A network communication system, comprising:

a single integrated convergent network controller (ICNC) chip; and

a single Ethernet connector for handling a plurality of layer 2/layer 4/layer 5 (L2/L4/L5) types of network traffic transported via a single fabric, wherein;

the single Ethernet connector is coupled to the single ICNC chip;

the single fabric is a physical link coupled to a plurality of servers;

the single ICNC chip comprises an L2/L4/L5 adapter operable to process the plurality of L2/L4/L5 types of network traffic for the plurality of servers, wherein the plurality of L2/L4/L5 types of network traffic comprise;

network traffic, storage traffic, interprocess communication (IPC) traffic and cluster traffic, which are transported via the single fabric, wherein the network traffic comprises Internet or Ethernet traffic, and wherein the storage traffic comprises traffic from storage devices accessible via a network.

2. The network communication system according to claim 1, wherein:

the plurality of servers comprises a blade server, and

the single ICNC chip is part of a blade mounted in the blade server.

3. The network communication system according to claim 2, wherein the blade server has a single Internet protocol (IP) address.

4. The network communication system according to claim 1, wherein the plurality of servers is part of a data center, and the data center comprises a plurality of other servers coupled to each other via the single fabric.

5. A method for communication, the method comprising:

in a data center;

accessing a storage system over a single fabric, wherein said single fabric is a physical link comprises a single layer 2 (L2) connector coupled to a single integrated convergent network controller (ICNC) chip, wherein;

the ICNC chip comprises an L2/L4/L5 adapter operable to process a plurality of layer 2/layer 4/layer 5 (L2/L4/L5) types of traffic, wherein the plurality of L2/L4/L5 types of network traffic comprise;

network traffic, storage traffic, interprocess communication (IPC) traffic and cluster traffic; and

accessing one or more of a cluster and a network over said single fabric, wherein the network traffic comprises Internet or Ethernet traffic, and wherein the storage traffic comprises traffic from storage devices accessible via a network.

6. The method according to claim 5, wherein said accessing of said storage system, over said single fabric are performed over a single Ethernet connector of a server in the data center.

7. The method according to claim 5, wherein said single integrated convergent network controller chip coupled to the single Ethernet connector has a single Internet protocol (IP) address.

8. A system for communication, the system comprising:

a single integrated convergent network controller (ICNC) chip, said ICNC chip comprises an L2/L4/L5 adapter that enables processing functionalities of a plurality of layer 2/layer 4/layer 5 (L2/L4/L5) types of traffic that are received via a single layer 2 (L2) connector that is communicatively coupled to a plurality of servers via a single physical link fabric, wherein the plurality of L2/L4/L5 types of network traffic comprise;

network traffic, storage traffic, interprocess communication (IPC) traffic and cluster traffic, wherein the network traffic comprises Internet or Ethernet traffic, and wherein the storage traffic comprises traffic from storage devices accessible via a network.

9. The system of claim 8, wherein said single integrated convergent network controller chip comprises a layer 2 network interface card (L2 NIC), a transmission control protocol (TCP) processor, an iSCSI processor, a remote direct memory access (RDMA) processor and a Management Agent processor.

10. A method for communication, the method comprising:

receiving a plurality of layer 2/layer 4/layer 5 (L2/L4/L5) types of traffic at a single layer 2 (L2) connector that is communicatively coupled to a plurality of servers via a single physical link fabric; and

processing the plurality of L2/L4/L5 types of traffic for the plurality of servers via a single integrated convergent network controller (ICNC) chip, said ICNC chip comprises an L2/L4/L5 adapter that enables processing functionalities of the plurality of,

wherein the plurality of L2/L4/L5 types of network traffic comprise;

network traffic, storage traffic, interprocess communication (IPC) traffic and cluster traffic, wherein the network traffic comprises Internet or Ethernet traffic, and wherein the storage traffic comprises traffic from storage devices accessible via a network.

11. The method of claim 10, wherein said single ICNC chip comprises a layer 2 network interface card (L2 NIC), a transmission control protocol (TCP) processor, an iSCSI processor, a remote direct memory access (RDMA) processor and a Management Agent processor.
