    Server Description

    A storage-optimized virtual server featuring thirty terabytes of local NVMe SSD storage and fifty gigabits per second baseline network bandwidth.

    Storage & DatabaseMemory Optimized

    Amazon Web Services i3en.12xlarge is a storage-optimized instance designed for high-capacity local storage and memory-intensive workloads. Powered by an Intel Xeon 8259CL processor with 48 vCPUs and 24 physical cores, it features 384.0 GB of DDR4 RAM and 30,000 GB of local NVMe SSD storage. Operating on the AWS Nitro hypervisor, the instance provides a baseline network bandwidth of 50 Gbps. Benchmark results show average multi-core CPU and memory bandwidth performance, though single-core performance is relatively weak, placing in the bottom 25%. This hardware profile offers strong qualitative cost efficiency for storage-heavy deployments, making it highly suitable for large-scale databases, NoSQL data stores, and distributed file systems that benefit from massive local NVMe capacity and high network throughput.

    Workload Profiles

    1.64Score
    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.
