Low latency NX10G form factor module to an enhanced small form-factor pluggable uplink extender to maximize host port density

摘要

A system, method and apparatus is provided for optimizing network data communications. At an extender device, a data signal is received at a host link port across a data cable that is interfaced with the host link port. The host link port is configured to receive the data signal. The data cable is configured to carry management communications and data communications between a switch host device and the extender unit device. The data signal is split into data signal components. Each of the data signal components comprises a ten gigabit per second portion of the data signal. The data signal components are sent to one or more network devices via one or more corresponding data transmission ports.

1. A system comprising:
a switch host device comprising one or more host ports, each of which is configured to interface with either an enhanced quad-small form-factor pluggable (QSFP+) transceiver module capable of sending and receiving data at a first data rate of 40 gigabits per second (40G) or with a 12× small form-factor pluggable CXP transceiver module capable of sending and receiving data at a second data rate of up to 120 gigabits per second (120G); one or more extender units, each of which comprises a host link port and-a plurality of data transmission ports, wherein the data transmission ports are each configured to interface with an enhanced small form-factor pluggable (SFP+) transceiver module that is capable of sending and receiving data at a data transmission rate of up to 10 gigabits per second (10G); and a data cable with a first end configured to interface with one of the host ports of the switch host device and one or more second ends configured to interface with one or more of the host link ports of the extender units, wherein the data cable is configured to carry management communications and data communications between the switch host device and the one or more extender units, wherein the data cable is a custom CXP to 3× QSFP+ Y-data cable that, in response to 120G data being sent between the switch host device and the one or more extender units, is configured such that the first end interfaces with a CXP host port and wherein the one or more one or more second ends comprise three second ends each of which is configured to interface with a host link port of one of the extender units, and wherein each of the extender units comprises four SFP+ data transmission ports.
