Description
- The present disclosure relates in general to information handling systems, and more particularly to systems and methods for providing a high-density optical fiber connectivity to a switch or other information handling system.
- As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
- An information handling system may have a network interface or other input/output (I/O) interface having an optical port, including an optical interface for communication of data via an optical cable. An example of such information handling system includes a switch having multiple optical ports, each optical port configured to receive a corresponding optical cable.
- Industry forecasts suggest that processors (e.g., an application-specific integrated circuit) for future generation optical switches may support 51.2-terabit/second switch capacity, meaning a co-packaged optics processor may support 1024 optical fibers using a parallel opto-electronic interface. To fully support such increase in switch capacity, switch front panels at where optical ports are present may require presence of significantly more optical ports than are present in existing switches. For example, while traditional implementations may use switches sized at one rack unit (RU) and have sufficient front panel area to support the needed number of optical ports, advances in accordance with industry forecasts described above may require the use of a significantly increased number of optical ports.
- While an obvious solution may be to simply increase physical dimensions of a switch to enlarge the front panel, such a solution has its own disadvantage of taking up additional space, which may be undesirable in a data center environment for which it is desired to maximize the number of computing devices present in the data center.
- In accordance with the teachings of the present disclosure, the disadvantages and problems associated with existing optical switches may be reduced or eliminated.
- In accordance with embodiments of the present disclosure, an information handling system may include a processor and a plurality of ports communicatively coupled to the processor, and physically arranged in a first row and a second row at an exterior panel of an enclosure of the information handling system, such that the plurality of ports includes front ports of the first row visible when the exterior panel is viewed head on, rear ports of the first row located directly behind the front ports of the first row from a perspective in which the exterior panel is viewed head on, front ports of the second row visible when the exterior panel is viewed head on, and rear ports of the second row located directly behind the front ports of the second row from the perspective in which the exterior panel is viewed head on.
- In accordance with these and other embodiments of the present disclosure, a method may include coupling a plurality of ports to a processor, physically arranging the plurality of ports in a first row and a second row at an exterior panel of an enclosure of an information handling system comprising the plurality of ports and the processor, such that the plurality of ports includes: front ports of the first row visible when the exterior panel is viewed head on, rear ports of the first row located directly behind the front ports of the first row from a perspective in which the exterior panel is viewed head on, front ports of the second row visible when the exterior panel is viewed head on, and rear ports of the second row located directly behind the front ports of the second row from the perspective in which the exterior panel is viewed head on.
