Which of the following specifications is correct for NVMe disk enclosures (Intellegent DAE)?

Question

Options

• A25 disks per 1U
• B25 disks per 2U
• C36 disks per 1U
• D36 disks per 2U

• A
  9% (5)
• B
  15% (8)
• C
  4% (2)
• D
  72% (39)

Explanation

Option D (36 disks per 2U) matches the standard specification for NVMe Intelligent DAE (Disk Array Enclosure) units used in enterprise storage systems, balancing high-density drive capacity with the physical constraints of the 2U rack form factor. Options A and C (1U configurations) are incorrect because fitting 25 or 36 NVMe drives into a single rack unit is physically infeasible - NVMe drives and their required backplane connectors, cooling, and power delivery demand more vertical space than 1U (44.45mm) provides. Option B (25 disks per 2U) is incorrect because while 25 drives in 2U is physically plausible, it understates the actual capacity; 25-disk configurations are more typical of SAS/SATA enclosures, not the higher-density NVMe intelligent enclosures. Memory tip: Associate "NVMe Intelligent DAE" with the number 36-2 - think of it as "36 drives, 2U" and link "intelligent" to the higher drive count (36 > 25), since smarter/newer NVMe technology enables greater density per enclosure.
