OpenMetal Large v4 NVMe Drive Specs

Q: What NVMe drives does OpenMetal use in the Large v4 bare metal server?

The Large v4 ships with two 6.4 TB Micron 7500 MAX NVMe SSDs (12.8 TB total), connected via PCIe Gen4 x4 and running NVMe v2.0b.

See bare metal pricing

The Micron 7500 MAX uses 232-layer 3D TLC NAND with a 6-plane architecture and independent wordline read (iWL). Each 6,400 GB drive delivers 7,000 MB/s sequential read, 5,900 MB/s sequential write, 1.1 million random read IOPS, and 400,000 random write IOPS. Typical read latency is 70 microseconds, with sub-1ms QoS guaranteed at 99.9999% (six nines) for 4KB random reads up to QD128.

Endurance is rated at 3 DWPD (drive writes per day), translating to 35,040 TB total bytes written over the five-year warranty period. MTTF is 2 million hours at 0-55C operating temperature. These drives are separate from the boot storage: OpenMetal isolates boot and data I/O using two dedicated 960 GB SSDs in RAID 1 for the OS, keeping system-level operations off the NVMe data pool entirely. The Large v4 chassis supports up to 6 total drives, leaving 2 open bays for additional NVMe capacity beyond the base configuration.
