A network system for a data center is described in which a switch fabric may provide full mesh interconnectivity such that any servers may communicate packet data to any other of the servers using any of a number of parallel data paths. Moreover, according to the techniques described herein, edge-positioned access nodes, optical permutation devices and core switches of the switch fabric may be configured and arranged in a way such that the parallel data paths provide single L2/L3 hop, full mesh interconnections between any pairwise combination of the access nodes, even in massive data centers having tens of thousands of servers. The plurality of optical permutation devices permute communications across the optical ports based on wavelength so as to provide, in some cases, full-mesh optical connectivity between edge-facing ports and core-facing ports.

A system root of trust device of a computing system authenticates boot images associated with data processing units of the computing system. The device includes at least one processor configured to determine whether a first set of boot code associated with a first processor of the computing system is authentic, in response to determining that the first set of boot code is authentic, reset the first processor to allow the first processor to boot and authenticate first executable code to be executed by the first processor, after resetting the first processor, determine whether a second set of boot code associated with a second processor of the computing system is authentic, and in response to determining that the second set of boot code is authentic, reset the second processor to allow the second processor to boot and to authenticate second executable code to be executed by the second processor.

In one example, a data processing unit (DPU) includes a host unit interface for communicatively coupling to second device via a serial input/output (I/O) connection, and a control unit implemented in circuitry and configured to initially configure the host unit interface of a data processing unit to operate in endpoint mode, determine that the host unit interface of the data processing unit is to switch from operating in the endpoint mode to root complex mode, in response to determining that the host unit interface is to switch from operating in the endpoint mode to the root complex mode: configure the host unit interface to operate in the root complex mode, and send data to an I/O expander unit to cause the I/O expander unit to issue a reset signal to the second device, the second device being configured to operate in the endpoint mode.

A system may comprise a first group of switches, each switch including a first group of inputs and outputs, and a first group of controllers, each controller being independent from one another and corresponding to a switch of the first group of switches, to selectively control the switch to connect the switch's inputs with outputs. The first group of switches and controllers may be installed in a chassis. The system may comprise a second group of switches, each switch including a second group of inputs and outputs, and a second group of controllers, each controller corresponding to a switch of the second group of switches, to selectively control the switch to connect the switch's inputs with outputs. The second group of controllers may control and connect, via a group of control links, to the first group of controllers.

Techniques are described for an electronic device in which a communication plane having a plurality of slots for receiving communication cards further includes an interface for receiving a pluggable module that operates to relay signals within the communication plane. The electronic device includes a plurality of removable communication cards and a communication plane having slots for receiving the plurality of removable communication cards. The electronic device also includes the pluggable module that is removably coupled to and external from the communication plane. The pluggable module receives a signal from a transmitting communication card from off of the communication plane, compensates for loss experienced by the signal or loss that will be experienced by the signal, and transmits the compensated signal back onto the communication plane and to a receiving communication card.
