Server Description
A compute-optimized virtual server featuring forty-eight dedicated Intel Xeon cores and a high-speed twenty-five gigabit network baseline.
Alibaba Cloud ecs.c9i.12xlarge is an x86_64 compute-optimized server instance featuring 48 dedicated vCPUs powered by an Intel Xeon 6982P-C processor operating at 3.2 GHz. The instance is equipped with 96.0 GB of RAM, providing a resource density of 2.0 GB per core. It does not include local storage or GPU hardware, relying instead on network-attached storage options. Network performance is anchored by a baseline bandwidth of 25 Gbps. Running on the KVM hypervisor, this instance is structured for workloads that demand high CPU allocation relative to memory capacity. The resource configuration makes it qualitatively cost-efficient for compute-bound applications, including batch processing, web serving, and distributed compilation, where massive memory footprints are unnecessary.
