      CPU and System Topology

      Server Description

      A memory-optimized dedicated instance featuring high RAM density and Intel Xeon processing for demanding in-memory databases and caching workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.hfr6.10xlarge is a memory-optimized instance featuring 40 dedicated physical cores powered by an Intel Xeon 8269CY processor running at 3.1 GHz. Built on the x86_64 architecture and KVM hypervisor, it delivers 384.0 GB of RAM, translating to a high resource density of 9.6 GB per core. The instance lacks local storage and GPU accelerators, utilizing a baseline network bandwidth of 12 Gbps. Benchmark results show solid mid-range performance, with a PassMark CPU score of 34031.19 and a Redis throughput of 32.74 million SET operations per second. Memory bandwidth reaches 2128.36 GB/sec for cached small blocks and 111.38 GB/sec for uncached large blocks. These specifications make the instance highly efficient for in-memory databases, caching layers, and memory-intensive enterprise applications that require dedicated compute resources without local storage dependencies.

      Workload Profiles

      1.54Score
      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.
