      Server Description

      A massive memory-optimized instance featuring six terabytes of RAM and four hundred forty-eight vCPUs for enterprise-scale in-memory workloads.

      Memory Optimized

      Amazon Web Services u-6tb1.112xlarge is a memory-optimized instance designed for massive in-memory workloads. Running on the Nitro hypervisor, it features 448 vCPUs and 6144.0 GB of DDR4 memory, delivering 13.71 GB of RAM per core. The instance provides a baseline network bandwidth of 100 Gbps but lacks local storage. Benchmark data highlights top-tier multi-core CPU performance and exceptional memory bandwidth, though single-core performance and certain memory latency metrics rank lower. Qualitatively, this instance offers high resource density for memory-bound applications, making it highly efficient for enterprise-scale in-memory databases and large-scale data processing.

      Workload Profiles

      7.2Score
      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.
