      CPU and System Topology

      Server Description

      A memory-optimized x86 server featuring dedicated Intel Xeon processors and high memory density for demanding database and caching workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.hfr6.10xlarge is a memory-optimized server instance featuring 40 dedicated vCPUs and 384.0 GB of RAM, powered by an Intel Xeon 8269CY processor running at 3.1 GHz. Utilizing the KVM hypervisor, this x86_64 architecture server provides 9.6 GB of memory per core but does not include local storage or GPU accelerators. It delivers a baseline network bandwidth of 12 Gbps. Benchmark results show solid performance, including a Redis SET throughput of 32.74 million operations per second and a PassMark database score of 14328.81. The instance is highly suited for memory-intensive workloads such as in-memory databases, caching layers, and enterprise applications requiring a high memory-to-vCPU ratio without the need for local NVMe storage.

      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.
