    Server Description

    An ARM64 storage-optimized instance featuring fifteen terabytes of local NVMe SSD storage and ninety-six gigabytes of system memory.

    Storage & DatabaseGeneral Purpose

    Amazon Web Services is4gen.4xlarge is a storage-optimized instance powered by a 16-core AWS Graviton Neoverse-N1 ARM64 processor running at 2.5 GHz. It features 96 GB of system memory and a baseline network bandwidth of 25 Gbps. The defining hardware feature is its bundled 15,000 GB of local NVMe SSD storage, offering high storage density. Benchmark data shows average multi-core CPU and database performance, with the instance achieving 19.11 million operations per second in Redis SET tests and average marks in Passmark database operations. However, single-threaded performance is a tradeoff, scoring weakly in Geekbench single-core and single-threaded compression tests. This instance provides qualitative cost efficiency for storage-heavy deployments by pairing dense local NVMe storage with energy-efficient ARM architecture. It is best suited for transactional databases, caching layers, and distributed file systems.

    Workload Profiles

    0.954Score
    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.
