Server Description
A memory-optimized server featuring one terabyte of RAM and high-bandwidth networking for demanding database and memory-cached workloads.
Amazon Web Services r6i.32xlarge is an x86_64 memory-optimized server instance running on the AWS Nitro hypervisor. It is configured with 128 vCPUs across 64 physical cores of an Intel Xeon 8375C processor operating at 3.5 GHz, paired with 1024.0 GB of DDR4 memory. The instance does not include local storage, relying instead on network-attached storage, but features a 50 Gbps baseline network bandwidth. Benchmark results show top-tier performance in Passmark CPU encryption and overall CPU scores, alongside strong multi-core processing and memory bandwidth. However, single-core performance remains average. This hardware profile is suited for memory-intensive workloads, including large-scale database operations, Redis caching, and software compilation, where high memory density and dedicated CPU allocation are required.
