Server Description
A memory-optimized virtual server featuring dedicated AMD EPYC processors and a high memory-to-core ratio for demanding enterprise workloads.
Alibaba Cloud ecs.r7a-nps1.16xlarge is a memory-optimized instance built on the KVM hypervisor and powered by AMD EPYC 7T83 processors. It features 64 dedicated x86_64 vCPUs running at 2.55 GHz and 512.0 GB of RAM, establishing an 8.0 GB memory-to-core ratio. The instance does not include local storage, relying instead on network-attached storage options, and delivers a baseline network bandwidth of 16 Gbps. With dedicated CPU allocation, it provides predictable compute performance without resource contention. This hardware profile is qualitatively cost-efficient for memory-heavy workloads that do not require proportional scaling of compute resources. The ecs.r7a-nps1.16xlarge is suited for in-memory databases, large-scale caching, enterprise applications, and memory-intensive data processing tasks.
