Server Description
A memory-optimized virtual server featuring dedicated Intel Xeon processors and a high RAM-to-vCPU ratio for memory-intensive enterprise workloads.
Alibaba Cloud ecs.r9i.4xlarge is a memory-optimized virtual machine instance configured with 16 dedicated vCPUs and 128.0 GB of RAM, yielding a ratio of 8.0 GB of memory per core. Powered by the KVM hypervisor, the instance runs on an Intel Xeon 6982P-C processor with an x86_64 architecture and a clock speed of 3.2 GHz. This server does not feature local storage or integrated GPUs, relying instead on network-attached storage solutions. It delivers a baseline network bandwidth of 12 Gbps and includes no complimentary public IPv4 addresses. The high memory density makes this instance class qualitatively cost-efficient for memory-bound workloads that do not scale with high CPU core counts. It is suitable for database hosting, in-memory caching, and enterprise applications.
