Server Description
A memory-optimized x86_64 instance featuring dedicated AMD EPYC processors and high memory density for demanding enterprise workloads.
Alibaba Cloud ecs.r9ae.12xlarge is a memory-optimized server instance powered by the KVM hypervisor and AMD EPYC 9T95 processors. It features 48 dedicated x86_64 vCPUs running at 2.25 GHz and 384.0 GB of RAM, establishing a high memory-to-vCPU ratio of 8.0 GB per core. The instance does not include local storage or GPU accelerators, relying entirely on network-attached storage for data persistence. It provides a baseline network bandwidth of 25 Gbps to support data transfers. This hardware profile is qualitatively cost-efficient for memory-heavy workloads that do not require local NVMe drives. The ecs.r9ae.12xlarge is designed for large-scale databases, in-memory caching, enterprise applications, and data analytics pipelines.
