ecs.hfr9i.3xlarge by Alibaba Cloud

A memory-optimized server with dedicated single-threaded cores and high memory density for predictable database and caching performance.

Alibaba Cloud ecs.hfr9i.3xlarge is a memory-optimized x86_64 server instance featuring 12 dedicated vCPUs and 12 physical cores powered by an Intel Xeon 6982P-C processor running at 3.4 GHz. With a single thread per core configuration and KVM virtualization, it delivers predictable compute performance. The instance is equipped with 96.0 GB of RAM, establishing an 8.0 GB per core memory-to-vCPU ratio. It does not include local storage or GPU resources, relying instead on network-attached storage, and provides a baseline network bandwidth of 10 Gbps. This hardware profile is designed for memory-intensive workloads, such as database hosting, caching layers, and enterprise applications, where dedicated CPU allocation and high memory density are required to prevent resource contention.
