Server Description
A memory-optimized virtual server featuring dedicated Intel Xeon processors and a high memory-to-core ratio for memory-intensive enterprise workloads.
Alibaba Cloud ecs.r8i.3xlarge is a memory-optimized instance featuring 12 dedicated vCPUs and 96.0 GB of RAM, running on the x86_64 architecture. Powered by an Intel Xeon 8475B processor clocked at 2.7 GHz under the KVM hypervisor, this server provides a high memory-to-core ratio of 8.0 GB per vCPU. The instance does not include local storage, requiring network-attached storage solutions, and offers a baseline network bandwidth of 10 Gbps with zero complimentary public IPv4 addresses. Lacking integrated GPUs or local NVMe drives, it represents a specialized resource profile optimized for memory-dense workloads. This configuration is highly suited for in-memory databases, caching layers, enterprise applications, and data processing tasks where memory capacity and dedicated CPU performance are critical.
