Server Description
A memory-optimized virtual server featuring dedicated Intel Xeon processors and high memory density for enterprise database and caching workloads.
Alibaba Cloud ecs.r9i.12xlarge is a memory-optimized instance featuring 48 dedicated vCPUs powered by an Intel Xeon 6982P-C processor running at 3.2 GHz on the x86_64 architecture. Built on the KVM hypervisor, it provides 384.0 GB of RAM, establishing a high memory-to-vCPU ratio of 8.0 GB per core. The instance lacks local storage and GPU accelerators, relying entirely on network-attached storage and standard CPU processing. It offers a baseline network bandwidth of 25 Gbps. This resource profile is designed for memory-intensive enterprise applications, in-memory databases, and large-scale caching layers that require dedicated compute resources and substantial memory capacity without the need for local NVMe drives or hardware acceleration.
