An Ethernet solid-state drive (eSSD) system includes a plurality of eSSDs, an Ethernet switch and a baseboard management controller. The Ethernet switch is coupled to each of the eSSDs, and the baseboard management controller is coupled to the each of the eSSDs and to the Ethernet switch. The baseboard management controller controls the Ethernet switch to provide to each eSSD a corresponding predetermined bandwidth that is based on bandwidth information for the eSSD that is stored in a policy table of the baseboard management controller. The at least one predetermined bandwidth may include a predetermined ingress bandwidth and a predetermined egress bandwidth for the corresponding eSSD. The at least one predetermined bandwidth may be based on a service level associated with the corresponding eSSD, and may be adaptively based on operating parameters of the corresponding eSSD.

A routing establishing method for constructing a routing of a chain network including communication routers, each including a wired communication module, a wireless communication module, and a device configuration file. In a wired exploration procedure, exploration is performed by the source communication router through the wired communication module to obtain a wired communication status between the source and the destination communication routers. In a wireless exploration procedure, exploration is performed by the source communication router through the wireless communication module to obtain a wireless communication status between the source and the destination communication routers. In a routing decision procedure, next hop of the source communication router and whether the transmission routing is through the wired or the wireless communication module are determined and set according to the wired and the wireless communication status. The device configuration file includes device numbers related to relative positions of the communication routers.

A system and method support can subnet management in a cloud environment. During a virtual machine migration in a cloud environment, a subnet manager can become a bottleneck point that delays efficient service. A system and method can alleviate this bottleneck point by ensuring a virtual machine retains a plurality of addresses after migration. The system and method can further allow for each host node within the cloud environment to be associated with a local cache that virtual machines can utilize when re-establishing communication with a migrated virtual machine.

Technologies for dynamic accelerator selection include a compute sled. The compute sled includes a network interface controller to communicate with a remote accelerator of an accelerator sled over a network, where the network interface controller includes a local accelerator and a compute engine. The compute engine is to obtain network telemetry data indicative of a level of bandwidth saturation of the network. The compute engine is also to determine whether to accelerate a function managed by the compute sled. The compute engine is further to determine, in response to a determination to accelerate the function, whether to offload the function to the remote accelerator of the accelerator sled based on the telemetry data. Also the compute engine is to assign, in response a determination not to offload the function to the remote accelerator, the function to the local accelerator of the network interface controller.
