      CPU and System Topology

      Server Description

      A storage-dense virtual server featuring sixty-four dedicated cores and over seven terabytes of local SSD storage for parallelized database workloads.

      Storage & DatabaseGeneral Purpose

      Alibaba Cloud ecs.i2g.16xlarge is an x86_64 virtual server featuring 64 dedicated vCPUs from an Intel Xeon 8163 processor, 256.0 GB of RAM, and a substantial 7679 GB of local SSD storage. Operating on the KVM hypervisor, it delivers a baseline network bandwidth of 10 Gbps. Benchmark data reveals a contrast in performance: single-core metrics and single-threaded operations are weak, whereas multi-core processing, memory bandwidth, and database operations consistently rank in the average tier. Multi-threaded decompression stands out as a strong point. Given its massive local storage capacity and balanced memory-to-vCPU ratio, this instance is qualitatively cost-effective for storage-intensive applications. It is highly suited for databases, multi-threaded data processing, static web serving, and general-purpose workloads that require large local storage volumes but do not demand high single-core compute performance.

      Workload Profiles

      1.5Score
      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.
