    Server Description

    An arm64 storage-optimized instance featuring thirty terabytes of local NVMe SSD storage and high-bandwidth networking for data-intensive workloads.

    Storage & DatabaseGeneral Purpose

    Amazon Web Services im4gn.16xlarge is a storage-optimized server featuring 64 dedicated AWS Graviton Neoverse-N1 cores on the arm64 architecture, running at 2.5 GHz. It is equipped with 256.0 GB of memory, 30,000 GB of local NVMe SSD storage, and a baseline network bandwidth of 100 Gbps under the Nitro hypervisor. Benchmarks show strong multi-core capabilities, particularly in Redis operations, static web serving, and software compilation, though single-threaded performance and LLM inference speeds represent clear tradeoffs. The custom ARM architecture delivers high resource density and qualitative cost efficiency for data-intensive deployments. This server is optimized for high-throughput databases, caching layers, and distributed storage workloads.

    Workload Profiles

    2.4Score
    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.
