ecs.r9i.16xlarge by Alibaba Cloud

A dedicated x86_64 compute platform featuring a high memory-to-core ratio and baseline network bandwidth of 28 Gbps for memory-intensive workloads.

Alibaba Cloud ecs.r9i.16xlarge is an x86_64 memory-optimized server instance configured with 64 dedicated physical cores and 512.0 GB of RAM. Powered by an Intel Xeon 6982P-C processor running at 3.2 GHz with a 1.0 thread-per-core ratio, it delivers dedicated compute resources without hyperthreading. The instance operates on a KVM hypervisor and features a baseline network bandwidth of 28 Gbps. It does not include local storage or integrated GPUs, relying instead on network-attached storage. With a high memory-to-vCPU ratio of 8.0 GB per core, this server is designed for memory-intensive enterprise workloads, including in-memory databases, large-scale caching, and data analytics pipelines that require predictable, non-shared CPU performance.
