Server Description
A high-density memory-optimized instance featuring dedicated AMD EPYC processors and high-throughput networking for memory-intensive enterprise workloads.
Alibaba Cloud ecs.r9ae.48xlarge is a memory-optimized virtual machine instance designed for resource-intensive enterprise workloads. Powered by the KVM hypervisor, it features 192 dedicated vCPUs on the x86_64 architecture, utilizing AMD EPYC 9T95 processors running at 2.25 GHz. The instance provides 1536.0 GB of system memory, establishing a high memory-to-core ratio of 8.0 GB per vCPU. It does not include local storage, meaning all storage requirements must be met via network-attached block storage. Network performance is supported by a baseline bandwidth of 100 Gbps. This server configuration is engineered for large-scale in-memory databases, extensive data caching, and memory-bound analytics applications that require massive RAM capacity and high-throughput networking without local storage dependencies.
