    Server Description

    A storage-optimized instance bundling 15 TB of local NVMe SSDs with 64 Intel vCPUs for demanding database and transactional workloads.

    Storage & DatabaseMemory Optimized

    Amazon Web Services i4i.16xlarge is a storage-optimized server instance powered by an Intel Xeon 8375C processor with 64 vCPUs and 512 GB of DDR4 RAM. Operating on the x86_64 architecture under the Nitro hypervisor, it features 15,000 GB of local NVMe SSD storage and a 38 Gbps baseline network bandwidth. Performance benchmarks show strong multi-core processing, software compilation, and database operations, though single-core execution and memory bandwidth remain in the average tier. This instance offers high resource density by bundling massive local storage with substantial memory, making it qualitatively cost-effective for I/O-intensive workloads. It is highly suited for large-scale databases, transactional applications, and multi-threaded data processing tasks.

    Workload Profiles

    2.61Score
    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.
