We primarily rely on modern Dell servers as our high availability cluster nodes. Each of them is equipped with an Intel Xeon E5v3 or higher CPU. As an atomic CPU resource allocation unit, we use virtual CPUs (vCPU), which maps to one physical CPU core with at least 2Ghz frequency. Our computing clusters are built in such a way that there is always at least one host reserved for failover (N+1 redundancy), which always ensures maximum uptime. Production networking is fully redundant and is built on HPE and Dell enterprise level hardware. Each host connects to the core network with at least 2 redundant 10GbE links. If your project has any special requirements for networking, it is possible to install and host a dedicated network equipment just for You.
