Server Description
Memory-optimized server with 64 dedicated Intel Xeon vCPUs, 512 GB system memory, and 20 Gbps network throughput for enterprise workloads.
Alibaba Cloud ecs.r5.16xlarge is a memory-optimized instance in the ecs.r5 server family. It is equipped with 64 dedicated vCPUs driven by Intel Xeon 8163 processors running at 2.5 GHz on an x86_64 architecture, alongside 512.0 GB of system memory. This configuration maintains an 8.0 GB RAM per vCPU ratio, making it structured for large memory requirements. Virtualized using KVM, the instance provides a baseline network bandwidth of 20 Gbps. It includes no bundled local storage or dedicated graphics processing units, relying entirely on external block storage for persistent data requirements. The substantial memory footprint offers cost efficiency by consolidating memory-bound applications onto fewer physical nodes. The instance is suited for memory-intensive workloads, including large enterprise in-memory databases, distributed caching systems, real-time data processing engines, and resource-heavy enterprise software applications.
