    Server Description

    A storage-optimized x86_64 platform featuring massive local NVMe SSD capacity and balanced memory for database and data-intensive workloads.

    Storage & DatabaseMemory Optimized

    Amazon Web Services i4i.12xlarge is a storage-optimized server running on the Nitro hypervisor, equipped with 48 vCPUs and 24 physical cores from an Intel Xeon 8375C processor clocked at 3.5 GHz. It features 384.0 GB of DDR4 memory and a substantial 11,250 GB of local NVMe SSD storage, alongside a 28 Gbps baseline network bandwidth. Performance benchmarks indicate average tier results for general compute, with a Passmark CPU score of 48,290.74, but show strong capabilities in CPU encryption and image processing. Database operations are supported by a Redis SET throughput of 44.86 million operations per second. However, the lack of a GPU limits its utility for large-scale AI tasks, as demonstrated by a weak 2.76 tokens per second in 70B LLM text generation. This instance is best suited for large databases, storage-heavy applications, and data processing workloads.

    Workload Profiles

    2.33Score
    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.
