ecs.r9ae.48xlarge by Alibaba Cloud

A high-density memory-optimized instance featuring dedicated AMD EPYC processors and high-speed networking for demanding enterprise database workloads.

Alibaba Cloud ecs.r9ae.48xlarge is an x86_64 memory-optimized server instance powered by an AMD EPYC 9T95 processor operating at 2.25 GHz. It features 192 dedicated physical cores and 192 vCPUs with a 1.0 thread-per-core configuration, eliminating hyperthreading resource sharing. The instance is equipped with 1536.0 GB of RAM, providing a memory-to-core ratio of 8.0 GB. It operates on the KVM hypervisor and delivers a baseline network bandwidth of 100 Gbps. This instance does not include local storage or integrated GPUs, relying on network-attached storage for data persistence. The high memory density and dedicated CPU allocation make this instance suitable for large-scale in-memory databases, enterprise resource planning systems, and complex data processing workloads that require consistent compute performance and substantial memory capacity.
