Connectivity for AI
High performance AI-optimised server and storage systems need an equally high-performance network infrastructure to support them and ensure there are no bottlenecks that effect data throughput. Whether located within a datacentre or at the edge of the network, connectivity is key to keep systems functioning optimally. The Scan AI networking solutions portfolio includes Ethernet, InfiniBand, wireless and 4G / 5G options to deliver best in class performance - whether you’re at the development, training or inferencing stage of your project.
NICs & Smart NICs
Although only a small component in an overall dev box or server, the Network Interface Card or NIC, can contribute to a huge uplift in performance. Basic server NICs use Ethernet as a protocol and offer throughput speeds of between 1Gbps (Gigabits per second) and 40Gbps, with at least 10Gbps required for applications such as machine learning, deep learning, AI and HPC. For training larger models these speeds are insufficient and a Smart NIC is required.
A Smart NIC, sometimes referred to as an HCA (Host Channel Adapter) when discussing InfiniBand technology, performs all the tasks of a regular NIC but in order to cope with higher throughput speeds a degree of off-loading is required to reduce pressure on other components in the server.
This means the network card itself performs some of the processing tasks, removing the latency usually introduced by the CPU, system memory and operating system (OS). This off-loading is referred to as Remote Memory Direct Access (RDMA) for InfiniBand cards and RDMA over converged Ethernet (RoCE) for Ethernet cards. To cope with software defined applications, it is likely a DPU will offer better performance.
Where there are software defined storage (SDS) or networking (SDN) applications being run on the server, smart NICs have been superseded by DPUs, in order to deliver further offloading of management tasks.

FIND OUT MOREData Processing Units
Data Processing Units (DPUs), sometimes also called Infrastructure Processing Units (IPUs), take the Smart NIC approach to the next level. Over and above the advanced off-loading that takes place on a Smart NIC a DPU is designed to be a datacentre infrastructure-on-a-chip - optimised for cloud workloads and high performance computing. It delivers a broad set of accelerated software-defined networking, storage, security, and management services with the ability to offload, accelerate and isolate datacentre infrastructure.
By combining high-speed networking connectivity - usually multiple 100 - 200Gbps interfaces - with its own OS (usually Linux based), an array of processor cores for crypto, management and storage offloads, a DPU offers purpose-built, hardware-acceleration engines with considerable logic programmability. Sitting at the edge of the server, a DPU card empowers agile, secure and high-performance cloud and AI workloads, all while reducing the total cost of ownership and increasing datacentre efficiency.

Although wired networking is the common approach for deep learning and AI workflows due to their high demands and time-critical nature, wireless network connectivity may also be required in other areas of your organisation. When wireless connectivity is used to support elements of your business, it must also be reliable, consistent and fast. To guarantee this performance businesses are turning increasingly to managed solutions whereby the various access points that cover any given area are controlled by either a master wireless access point (WAP) or an external controller, thus enabling greater control. Benefits of a solution like this include improved seamless hand-off as users roam between access points, better load balancing of user access across the wireless network and enhanced security - increasing the ability to monitor and detect rogue users - either with non-compliant devices or unauthorised access.
