    Server Description

    A high-density storage and memory-optimized ARM64 platform delivering top-tier database throughput and massive local NVMe SSD capacity.

    Storage & DatabaseMemory Optimized

    Amazon Web Services i8ge.18xlarge is a storage-optimized server featuring 72 dedicated physical cores on the ARMv9 Neoverse-V2 architecture running at 2.8 GHz. Operating on the Nitro hypervisor, this instance is equipped with 576.0 GB of RAM and a substantial 45,000 GB of local NVMe SSD storage, supported by a 112 Gbps baseline network bandwidth. Benchmark data highlights top-tier performance in memory bandwidth, Redis SET operations, database processing, and static web serving, alongside strong multi-core compute capabilities. Conversely, single-core performance and single-threaded compression tasks remain in the average tier. Given its high storage density and memory bandwidth, this server is highly suited for large-scale databases, high-throughput caching layers, and memory-intensive data processing workloads.

    Workload Profiles

    4.7Score
    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.
