Server Description
A memory-optimized virtual server featuring dedicated AMD EPYC processors and a high memory-to-core ratio for memory-intensive enterprise workloads.
Alibaba Cloud ecs.r8a.16xlarge is a memory-optimized instance featuring 64 dedicated vCPUs and 512.0 GB of RAM, yielding a high memory-to-vCPU ratio of 8.0 GB per core. Powered by AMD EPYC 9T24 processors running at 2.7 GHz on the x86_64 architecture, this KVM-based instance allocates one thread per physical core to ensure dedicated, predictable compute performance. The instance does not include local storage or GPU hardware, relying instead on external storage solutions and offering a baseline network bandwidth of 20 Gbps. The high memory density makes this instance qualitatively cost-efficient for memory-bound workloads. It is designed for enterprise applications, in-memory databases, large-scale caching, and data processing workloads that demand substantial memory capacity without the need for local NVMe drives or hardware accelerators.
