Abstract: Switches and groups of IO ports, conventionally integrated on a single shared PCB, may be divided into separate switch modules and IO modules that can be connected by high-speed low-loss management cables in a variety of configurations. Thereafter, the separate modules may be replaced independently of each other. Some of the management connections may be parallel, similar to production-data connections. Alternatively, a series of IO modules (e.g., a chain or a ring) may be managed by a single switch module using a management method. The management method may include collecting and updating configuration and status information specific to each of the IO modules and, by extension, each of their IO ports. This enables the switch module to recognize, and thereafter ignore, unconnected ports, removing the performance penalty that sometimes arises when fewer than all available ports are connected. It also allows the switch module to rapidly adjust to addition, subtraction, and replacement of connected IO modules.

Abstract: Examples disclosed herein relate to fabric cable emulation. Some examples disclosed herein include determining connection data associated with a connection between a fabric interface of a cluster node in a fabric cluster and a fabric switch. Based on the determined connection data, configuration parameters for the connection may be calculated and stored in a memory device on the cluster node. An interface signal may be asserted to the fabric interface of the cluster node after the calculated configuration parameters are stored to indicate that the cluster node is available in the fabric cluster.
