Server Description
A high-density memory-optimized instance featuring eighty dedicated cores and nearly one terabyte of RAM for demanding enterprise workloads.
Alibaba Cloud ecs.re4.20xlarge is a memory-optimized virtual server running on the KVM hypervisor with an x86_64 architecture. It features 80 dedicated vCPUs and 960.0 GB of RAM, providing a high memory-to-core ratio of 12.0 GB per vCPU. The instance does not include local storage or GPU hardware, relying instead on external storage solutions, and delivers a baseline network bandwidth of 15 Gbps. This resource profile is qualitatively cost-efficient for consolidating large-scale workloads, reducing the overhead of multi-node cluster management. It is engineered for memory-intensive applications, such as in-memory databases, large-scale caching systems, and enterprise data processing.
