Server Description
A compute-optimized instance featuring forty-eight dedicated physical cores and a high-speed network interface for intensive processing workloads.
Alibaba Cloud ecs.c8i.12xlarge is a compute-optimized instance designed for high-performance workloads. Powered by an Intel Xeon 8475B processor running at 2.7 GHz, it provides 48 dedicated vCPUs mapped to 48 physical cores on an x86_64 architecture, utilizing a KVM hypervisor. With 96.0 GB of RAM, the instance maintains a 2.0 GB memory-to-core ratio, prioritizing raw processing power over memory capacity. It features a baseline network bandwidth of 25 Gbps but lacks local storage, requiring external block storage solutions. The dedicated CPU allocation ensures predictable execution without hyperthreading overhead. This configuration is suitable for compute-heavy applications, batch processing, and web serving.
