    Server Description

    A high-performance bare-metal platform combining massive memory capacity, fast NVMe storage, and high-speed networking for demanding enterprise databases.

    Memory OptimizedStorage & DatabaseCompute Optimized

    Amazon Web Services r6idn.metal is a bare-metal, memory-optimized server designed for resource-intensive enterprise workloads. Powered by an Intel Xeon 8375C processor with 128 vCPUs and 64 physical cores running at 3.5 GHz, it features 1024.0 GB of DDR4 memory and 7600 GB of local NVMe SSD storage. The instance delivers high-speed networking with a 200 Gbps baseline bandwidth. Performance benchmarks highlight strong multi-core capabilities, with a stress-ng multi-core score of 124999.69, and exceptional memory throughput, reaching 6698.67 GB/sec for cached small blocks. Database operations are highly efficient, supported by a Redis SET performance of 107.97 million operations per second. This bare-metal configuration is optimized for large-scale databases, in-memory data stores, and high-throughput data processing applications.

    Workload Profiles

    4.4Score
    Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
