Server Description
A memory-optimized virtual server featuring dedicated AMD EPYC processors and high memory density for demanding enterprise workloads.
Alibaba Cloud ecs.r9ae.16xlarge is a memory-optimized instance featuring 64 dedicated vCPUs and 512.0 GB of RAM, yielding a high resource density of 8.0 GB per core. Built on the x86_64 architecture, it is powered by an AMD EPYC 9T95 processor operating at 2.25 GHz under KVM virtualization. The instance provides a baseline network bandwidth of 32 Gbps but contains no local storage, requiring external block storage solutions. With zero integrated GPUs, this server is designed strictly for non-accelerated, memory-heavy workloads. Qualitatively, it offers high resource density for memory-bound applications without the added cost of local disks or accelerators. It is highly suited for in-memory databases, caching layers, and large-scale enterprise applications.
