      Server Description

      An ultra-high-density memory-optimized platform featuring eighteen terabytes of RAM for massive in-memory enterprise database workloads.

      Memory OptimizedStorage & Database

      Amazon Web Services u-18tb1.112xlarge is an x86_64 memory-optimized server featuring 448 vCPUs, 224 physical Intel Xeon 8280L cores, and 18,432 GB of DDR4 RAM. Operating on the Nitro hypervisor, it delivers a baseline network bandwidth of 100 Gbps but lacks local storage and GPUs. Benchmark data highlights top-tier multi-core CPU performance and exceptional memory bandwidth, alongside high-throughput Redis SET operations. However, single-core performance is relatively weak, and the PassMark memory score falls into the bottom 10%, indicating latency tradeoffs in massive multi-socket architectures. Qualitatively, this server represents a highly specialized, high-density hardware class where cost efficiency is optimized strictly for massive in-memory workloads. It is best suited for large-scale in-memory databases, enterprise ERP systems, and high-capacity caching layers.

      Workload Profiles

      7.39Score
      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.
