NVMe Drives in the OpenMetal Medium v5 Bare Metal Server

Q: What NVMe drives does OpenMetal use in the Medium v5 bare metal server?

The OpenMetal Medium v5 uses the Micron 7500 MAX 6.4 TB NVMe as its data drive, delivering 7,000 MB/s sequential read, 1.1 million random read IOPS, and sub-1ms latency at 99.9999% (6-nines) quality of service on a PCIe Gen4 interface.

The drive uses Micron’s 232-layer 3D TLC NAND with a 6-plane architecture and independent wordline read (iWL). Sequential write is 5,900 MB/s, random write is 400,000 IOPS, and typical read latency is 70 µs at the 99th percentile. Endurance is 35,040 TBW at 3 DWPD with a 5-year warranty. The Medium v5 ships with one drive in bay 1; up to three additional Micron 7500 MAX drives can be added for 25.6 TB total data capacity.

Boot storage is handled on separate hardware: two 960 GB NVMe drives in RAID 1 serve the OS independently from the data bays. This isolation means a failed or reimaged boot drive cannot affect data volumes, and swapping or expanding data drives does not change the boot configuration. Boot and data storage share no physical media on the Medium v5.
