    Server Description

    A storage-optimized instance featuring massive local NVMe SSD capacity and balanced memory for parallelized database and caching workloads.

    Storage & DatabaseMemory OptimizedGeneral Purpose

    Amazon Web Services i3.8xlarge is a storage-optimized instance built on the x86_64 architecture and the Xen hypervisor. It features an Intel Xeon E5-2686 v4 processor with 16 physical cores, 32 dedicated vCPUs, and 244.0 GB of RAM. A defining characteristic is its 7600 GB of local NVMe SSD storage, paired with a 12 Gbps baseline network bandwidth. Performance benchmarks indicate weak single-core capabilities, with single-threaded processing and large-block memory writes falling into the lower percentiles. Conversely, multi-threaded operations, database tasks, and Redis SET operations perform in the average range. This hardware profile offers qualitative cost efficiency for storage-intensive deployments that benefit from high local capacity and parallel execution. It is best suited for databases, caching layers, and distributed file systems rather than single-threaded compute tasks.

    Workload Profiles

    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.
