      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring high RAM density and dedicated AMD EPYC cores for caching and in-memory database workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r6a.2xlarge is a memory-optimized instance featuring 8 dedicated physical cores on an AMD EPYC 7H12 processor and 64.0 GB of RAM. Operating on the KVM hypervisor with an x86_64 architecture, this instance provides 8.0 GB of memory per core but lacks local storage and GPU accelerators. Performance benchmarks indicate a tradeoff: while single-core and multi-core CPU performance are weak to poor, cached memory bandwidth and PassMark database operations perform at average levels. The instance achieves 7.13 million operations per second in Redis SET benchmarks and a baseline network speed of 2 Gbps. Qualitatively, its high memory density makes it a cost-efficient choice for memory-bound workloads such as caching layers, in-memory databases, and web serving, rather than compute-intensive or storage-heavy applications.

      Workload Profiles

      0.396Score
      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.
