Server Description
A memory-optimized infrastructure solution featuring high-speed local NVMe storage, dedicated Intel Xeon processing, and high-bandwidth networking for demanding database workloads.
Memory OptimizedStorage & DatabaseGeneral Purpose
Amazon Web Services r6idn.12xlarge is a memory-optimized, network-optimized instance featuring 48 vCPUs and 24 physical cores powered by an Intel Xeon 8375C processor running at 3.5 GHz. Built on the Nitro hypervisor, it includes 384.0 GB of DDR4 memory and 2850 GB of local NVMe SSD storage. The instance delivers a baseline network bandwidth of 75 Gbps. In benchmark testing, it exhibits strong performance in CPU encryption and image processing, alongside a Redis throughput of 44.3 million SET operations per second. With its high memory-to-core ratio and fast local storage, the r6idn.12xlarge is highly efficient for memory-intensive databases, in-memory caching, high-throughput web serving, and data-intensive enterprise applications.
