OpenMetal Large v5 NVMe Drive Specs

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

The Large v5 ships with 2x 6.4 TB Micron 7500 MAX U.3 NVMe SSDs (12.8 TB total) — Micron’s mixed-use, 3 DWPD endurance class on 232-layer 3D TLC NAND with PCIe Gen4 x4 connectivity and a 5-year warranty.

See Large v5 specs

The Micron 7500 MAX is rated for 7,000 MB/s sequential read and 5,900 MB/s sequential write, 1.1 million random read IOPS and 400,000 random write IOPS, with typical read latency of 70 microseconds and 99th-percentile read latency of 80 microseconds. Mixed 70/30 read/write IOPS reach 650,000. Endurance is 35,040 TB written across the drive’s 5-year life (3 DWPD equivalent), with MTTF of 2 million hours at 0-55C and 2.5 million hours at 0-50C. QoS is sub-1ms at 99.9999% (6-nines) for 4KB random read up to QD128.

The 6-plane NAND architecture and independent wordline read (iWL) reduce read disturb and parallel-access conflicts, which matters for workloads with mixed I/O patterns — database WAL writes happening alongside large analytical reads, blockchain chain sync running in parallel with index lookups, Proxmox/KVM VMs generating mixed boot/data/swap I/O on the same host. The drive interface is NVMe v2.0b on PCIe Gen4 x4; the Xeon 6517P’s PCIe 5.0 lanes provide bandwidth headroom for future drive expansion using PCIe 5.0 NVMe drives without saturating the I/O subsystem.

These performance numbers are from Micron’s official 7500 NVMe SSD Tech Product Specification (Rev. A, 10/2023). Some Large v5 configurations may ship with the Micron 7450 MAX (E1.S form factor, same 3 DWPD class but slightly different performance envelope); the drive model is identified at order time and visible in the chassis BIOS/IPMI inventory after deployment. For the full performance envelope of both drive models, see the OpenMetal facts library or the manufacturer datasheets.
