A Conversation Over Coffee Between a DBA and an Infrastructure Architect
DBA: “Our SQL Server data volume is running at 85% IOPS capacity on the current Gen3 NVMe drives. If we do not upgrade before Q4, the holiday traffic will tip us over.”
Infrastructure Architect: “We have two options. Option A: Samsung PM9A3 7.68TB at 1,000K read IOPS. Option B: Kioxia CM7 at 2,700K read IOPS on Gen5. Both are overkill for your actual workload — you are running at 420K peak IOPS on a 24-drive array. You need higher IOPS per drive, not higher peak throughput.”
DBA: “So what is Option C?”
Infrastructure Architect: “Micrón 7450 PRO. 1,000K read IOPS, 1 DWPD, 7.68tuberculosis, but here is the difference: the 7450 uses 176-layer NAND with Micron’s in-house controller. The sustained write performance after the SLC cache is exhausted is 50% higher than the PM9A3 because the controller does not rely on a large SLC buffer to hit its spec sheet numbers. Your workload is 70% writes, sustained, all day. You need write consistency, not peak read IOPS.”
They ordered the 7450 PRO. The Q4 holiday traffic came and went without a single storage-related incident ticket.
