NVMe Storage in the OpenMetal H200 GPU Server

Q: What NVMe storage does the OpenMetal H200 GPU server use?

The OpenMetal H200 GPU server uses a 6.4TB Micron 7500 MAX NVMe SSD for data, plus two 960GB NVMe drives in RAID 1 for the boot volume, with capacity to add drives up to a 24-bay limit.

OpenMetal separates boot and data storage on every server, so a data-volume change never risks the boot environment. The 6.4TB Micron 7500 MAX is a PCIe Gen4, 232-layer 3D TLC drive rated at 3 DWPD (35,040 TBW) with a 5-year warranty, delivering about 7,000 MB/s sequential read, 5,900 MB/s sequential write, and up to 1,100,000 random read IOPS.

High sequential read throughput matters for GPU training: streaming sharded datasets and loading multi-hundred-GB checkpoints is read-bound, and roughly 7 GB/s per drive keeps the data loader ahead of the GPU. For inference, fast local NVMe keeps model-load and model-switch latency low.

Additional NVMe drives can be added up to a 24-bay limit for larger datasets and checkpoint storage, and the 1TB of DDR5-6400 host memory stages data above the NVMe tier.
