      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring high RAM density and dedicated Intel Xeon processors for memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r7se.8xlarge is a memory-optimized instance featuring 32 dedicated vCPUs and 256.0 GB of RAM, delivering a high memory-to-core ratio of 8.0 GB per vCPU. Powered by an Intel Xeon 8369B processor running at 2.9 GHz on the KVM hypervisor, this x86_64 server lacks local storage and dedicated GPUs, utilizing a 10 Gbps baseline network bandwidth. Performance benchmarks indicate average compute capabilities, but the instance excels in memory performance, scoring in the top 25% on the Passmark memory test and demonstrating strong text generation speeds for small language models. The absence of local storage requires network-attached storage solutions, making this instance best suited for memory-intensive workloads such as in-memory databases, caching layers, and large-scale data processing where high RAM density is critical.

      Workload Profiles

      1.8Score
      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.
