    Server Description

    A memory-optimized platform combining high-capacity DDR4 RAM, local NVMe storage, and 150 Gbps networking for demanding database and caching workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r6idn.24xlarge is a memory-optimized instance featuring 96 vCPUs and 48 physical cores powered by an Intel Xeon 8375C processor running at 3.5 GHz. It is equipped with 768.0 GB of DDR4 memory and 5700 GB of local NVMe SSD storage, operating on the Nitro hypervisor with a 150 Gbps baseline network bandwidth. Benchmark results place the instance in the top 25% for multi-core CPU performance, memory bandwidth, and database operations, with cryptographic performance reaching the top 10%. Conversely, single-core benchmarks and large LLM text generation speeds are average to weak. This hardware configuration is designed for memory-intensive databases, caching systems, and high-throughput web serving where local NVMe storage and high memory density offer qualitative resource efficiency.

    Workload Profiles

    4.1Score
    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.
