Described herein are systems, methods, and products utilizing a cache coherent switch on chip. The cache coherent switch on chip may utilize Compute Express Link (CXL) interconnect open standard and allow for multi-host access and the sharing of resources. The cache coherent switch on chip provides for resource sharing between components while independent of a system processor, removing the system processor as a bottleneck. Cache coherent switch on chip may further allow for cache coherency between various different components. Thus, for example, memories, accelerators, and/or other components within the disclose systems may each maintain caches, and the systems and techniques described herein allow for cache coherency between the different components of the system with minimal latency.

Composable infrastructure enabled by heterogeneous architecture, delivered by CXL based cached switch SOC and extensible via cxloverethernet (COE) protocols

A Compute Express Link™ (CXL) over Ethernet (COE) station is provided to bridge a CXL fabric and an Ethernet network to allow for efficient native memory load/store access to remotely connected resources. The COE station supports CXL and Ethernet traffic through its CXL interface, scheduler/packers, decoders, VOQs and VIQs by adding COE tags to Ethernet frames. In CXL controller mode, the CXL controller drives the VOQs. In Ethernet mode, the COE module drives the VOQs, and interacts with the MAC sublayer and the PMA sublayer, which are responsible for encoding and decoding data signals for transmission through a serializer/deserializer.

Methods and apparatus are provided for virtualizing resources such as host bus adapters connected to a storage area network. Resources are offloaded from individual servers onto a resource virtualization switch. Servers are connected to the resource virtualization switch using an I/O bus connection. Servers are assigned resources such as virtual host bus adapters and share access to physical host bus adapters included in the resource virtualization switch. Redundancy can be provided using multipathing mechanisms.

Resource virtualization mechanism including virtual host bus adapters

A hybrid server and multi-layer switch system architecture, referred to hereinafter as the Enterprise Fabric (EF) architecture, forms the basis for a number of Enterprise Server (ES) chassis embodiments. Each ES embodiment generally includes one or more Processor Memory Modules (PMMs, each generally having one or more symmetric multiprocessor complexes), one or more Network Modules, and a System Control Module (SCM). The SCM includes a cellified switching-fabric core (SF) and a System Intelligence Module (SIM). Each PMM has one or more resident Virtual IO Controller (VIOC) adapters. Each VIOC is a specialized I/O controller that includes embedded layer-2 forwarding and filtering functions and tightly couples the PMM to the SF. Thus the layer-2 switch functionality within the ES chassis is distributed over all of the SCM, NM, and PMM modules. Through the use of VIOC/VNIC device drivers, host operating system software (Host O/S) running on the PMMs is presented with a plurality of Virtual Network Interface Cards (VNICs). In some embodiments, each VNIC behaves as a high-performance Ethernet interface at the full disposal of the Host O/S. In other embodiments, at least some of the VNICs behave as high-performance Fibre Channel Host Bus Adapters.

Processor-memory module performance acceleration in fabric-backplane enterprise servers

Methods and apparatus are provided for virtualizing port adapter resources such as network interface cards (NICs) used to connect servers to packet based networks. Resources are offloaded from individual servers onto a resource virtualization switch. Servers connected to the resource virtualization switch using an I/O bus connection share access to NICs. Redundancy can be provided using multipathing mechanisms implemented at individual servers or high availability mechanisms implemented at the resource virtualization switch. Switchover can occur between ports on the same port adapter, between ports on separate adapters, or between ports on separate resource virtualization switches.

High availability and I/O aggregation for server environments

Pluggable modules communicate via a switch fabric dataplane accessible via a backplane. Various embodiments are comprised of varying numbers and arrangements of the pluggable modules in accordance with a system architecture that provides for provisioning virtual servers and clusters of servers from underlying hardware and software resources. The system architecture is a unifying solution for applications requiring a combination of computation and networking performance. Resources may be pooled, scaled, and reclaimed dynamically for new purposes as requirements change, using dynamic reconfiguration of virtual computing and communication hardware and software.

Methods and systems for handling inter-process and inter-module communications in  servers and server clusters

A networked computing system is taught that may be operated as one or more provisioned servers, each of the provisioned servers including capabilities as identified by a corresponding set of specifications and attributes, according to various embodiments. Typically the specifications (or constraints) and attributes are specified with a Server Configuration File. The networked computing system may be provisioned into any combination and number of servers according to needed processing and I/O capabilities. Each of these servers may include distinct compute, storage, and networking performance. Provisioned servers may be managed similar to conventional servers, including operations such as boot and shutting down.

Programmatic instantiation, and provisioning of servers

Methods and apparatus are provided for virtualizing resources including peripheral components and peripheral interfaces. Peripheral component such as hardware accelerators and peripheral interfaces such as port adapters are offloaded from individual servers onto a resource virtualization switch. Multiple servers are connected to the resource virtualization switch over an I/O bus fabric such as PCI Express or PCI-AS. The resource virtualization switch allows efficient access, sharing, management, and allocation of resources.
