      Server Description

      A memory-optimized virtual server featuring dedicated AMD EPYC processors and high RAM density for demanding enterprise database and caching workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r8a.12xlarge is a memory-optimized instance powered by the KVM hypervisor and an AMD EPYC 9T24 processor. It features 48 dedicated vCPUs across 48 physical cores with a 1.0 thread-per-core configuration, running at a clock speed of 2.7 GHz on the x86_64 architecture. The instance provides 384.0 GB of RAM, establishing a high memory-to-vCPU ratio of 8.0 GB per core. It does not feature local storage, relying entirely on network-attached storage options, and delivers a baseline network bandwidth of 16 Gbps. This hardware profile is designed to support memory-intensive enterprise applications, in-memory databases, and large-scale data processing tasks where high memory density is required relative to compute capacity.
