NVMe RAID Works. Dell's PERC 13 Proves It!

NVMe RAID isn’t a bottleneck anymore. We put Dell’s PERC 13 H975i through a full workout in a PowerEdge with 32 E3.S NVMe SSDs and dual H100 GPUs to see if hardware RAID can keep pace with Gen5 and AI. Short answer: yes. In our lab we measured big gains over PERC 12. Read bandwidth up about 90 percent. Write bandwidth up 318 percent. 4K random writes up more than 450 percent. We also tested during rebuilds, ran GDSIO and FIO, and looked at practical layout choices like Dell’s front-mount card design for cleaner cabling and better airflow. If you think NVMe RAID can't feed modern workloads, this data will change your mind. We cover performance, rebuild behavior, management via iDRAC and CLI, and how this architecture plays with GPUs for AI training and inference. Full Report - https://www.storagereview.com/review/...
