Technologies for switching network traffic include a network switch. The network switch includes one or more processors and communication circuitry coupled to the one or more processors. The communication circuity is capable of switching network traffic of multiple link layer protocols. Additionally, the network switch includes one or more memory devices storing instructions that, when executed, cause the network switch to receive, with the communication circuitry through an optical connection, network traffic to be forwarded, and determine a link layer protocol of the received network traffic. The instructions additionally cause the network switch to forward the network traffic as a function of the determined link layer protocol. Other embodiments are also described and claimed.

Technologies for optical communication in a rack cluster in a data center are disclosed. In the illustrative embodiment, a network switch is connected to each of 1,024 sleds by an optical cable that enables communication at a rate of 200 gigabits per second. The optical cable has low loss, allowing for long cable lengths, which in turn allows for connecting to a large number of sleds. The optical cable also has a very high intrinsic bandwidth limit, allowing for the bandwidth to be upgraded without upgrading the optical infrastructure.

In one embodiment, a device between a Controller Area Network (CAN)-based network and an Internet Protocol (IP)-based network receives a CAN message from a node in the CAN-based network. The CAN message comprises a CAN message identifier and a data field. The device determines an IP header based on the CAN message identifier and the CAN message. The device converts the data field of the CAN message into an IP message that includes the determined IP header. The device sends the IP message via the IP network to one or more eligible destinations for the IP message.

Technologies for compressing data with multiple hash tables include a compute device. The compute device is to produce, for each of multiple string prefixes of different string prefix sizes, an associated hash. Each string prefix defines a set of consecutive symbols in a string that starts at a present position in an input stream of symbols. The compute device is also to write, to a different hash table for each string prefix size, a pointer to the present position in association with the associated hash. Each hash is usable as an index into the associated hash table to provide the present position of the string.

Examples may include a sled for a rack of a data center including physical storage resources. The sled comprises an array of storage devices and an array of memory. The storage devices and memory are directly coupled to storage resource processing circuits which are themselves, directly coupled to dual-mode optical network interface circuitry. The dual-mode optical network interface circuitry can have a bandwidth equal to or greater than the storage devices.

Embodiments are generally directed apparatuses, methods, techniques and so forth determine an access level of operation based on an indication received via one or more network links from a pod management controller, and enable or disable a firmware update capability for a firmware device based on the access level of operation, the firmware update capability to change firmware for the firmware device. Embodiments may also include determining one or more configuration settings of a plurality of configuration settings to enable for configuration based on the access level of operation, and enable configuration of the one or more configuration settings.

A sled for operation in a corresponding rack of a data center includes a chassis-less circuit board substrate having one or more physical resources coupled to a top side of the chassis-less circuit board and one or more memory devices coupled to a bottom side of the chassis-less circuit board. The sled does not include a housing or chassis and is opened to the local environment. In the illustrative embodiments, the sled may be embodied as a compute sled, an accelerator sled, or a storage sled.
