Server Description
A memory-optimized instance featuring dedicated AMD EPYC cores, high memory density, and baseline network speeds of 32 Gbps.
Alibaba Cloud ecs.r9ae.16xlarge is a memory-optimized instance featuring 64 dedicated vCPUs and 512.0 GB of RAM, yielding an 8.0 GB per core ratio. Powered by an AMD EPYC 9T95 processor running at 2.25 GHz on the x86_64 architecture, this KVM-based server allocates one thread per physical core. The instance includes a 32 Gbps baseline network bandwidth but lacks local storage and GPU accelerators. The high memory-to-CPU ratio and dedicated core allocation make it suitable for memory-intensive enterprise applications, in-memory databases, and caching layers that require predictable compute resources without hyperthreading overhead.
