VCP-VVF IT Architectures Technologies Standards Practice Question
An enterprise storage architect is designing a vSphere Foundation 9.0 vSAN cluster using native NVMe drives. When configuring the vSAN disk group or express storage architecture (ESA), what is the architectural difference between Original Storage Architecture (OSA) and Express Storage Architecture (ESA)?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
ESA uses a streamlined single-tier architecture optimized for high-performance NVMe media without explicit cache/capacity disk groups, whereas OSA uses a two-tier caching architecture.
vSAN ESA is designed for high-performance NVMe media, processing I/O with a single-tier architecture that eliminates caching overhead, whereas OSA uses a two-tier cache/capacity disk group design.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
OSA requires Fibre Channel HBAs, whereas ESA runs exclusively over wireless Wi-Fi 7 networks.
Why it's wrong here
Neither vSAN architecture uses wireless networks; both run over standard Ethernet IP fabrics.
- ✓
ESA uses a streamlined single-tier architecture optimized for high-performance NVMe media without explicit cache/capacity disk groups, whereas OSA uses a two-tier caching architecture.
Why this is correct
Correct. ESA eliminates the cache tier requirement found in OSA, processing writes directly and efficiently on NVMe devices.
- ✗
OSA does not support virtual machine creation, whereas ESA only supports Windows 3.1 workloads.
Why it's wrong here
Both architectures support standard enterprise virtual machine workloads.
- ✗
ESA is designed exclusively for mechanical 5400 RPM hard disk drives, while OSA requires tape libraries.
Why it's wrong here
ESA requires high-performance NVMe storage, not mechanical or tape drives.
