2V0-21.23 Question 83
Single answerA company is planning to upgrade their current vSAN cluster to vSAN 8 with Express Storage Architecture (ESA). During the planning phase, they want to ensure that they meet the requirements and understand the advantages of ESA. Which of the following statements about ESA is correct?
- A
ESA requires the use of NVMe-based storage devices for optimal performance.
- B
ESA supports hybrid configurations with a mix of SSDs and HDDs for cost efficiency.
- C
ESA eliminates the need for a caching tier in vSAN clusters.
- D
ESA is compatible with vSAN clusters running on any hardware certified for vSphere.
Show answer and explanation
Correct answer: A
Explanation
Express Storage Architecture (ESA) in vSAN 8 is a next-generation architecture designed to deliver high performance and efficiency by leveraging NVMe-based storage devices and an optimized storage stack. It supports only all-flash configurations and requires ESA-compatible hardware. This ensures the full benefits of ESA, such as improved performance and reduced complexity, are realized.
- A. Correct.
Correct: ESA leverages NVMe-based storage devices to provide high throughput, low latency, and optimized performance.
- B. Incorrect.
Incorrect: ESA is designed for all-flash configurations and does not support hybrid setups. Hybrid setups are supported by the Original Storage Architecture (OSA).
- C. Incorrect.
Incorrect: While ESA simplifies the storage stack, it still requires optimized storage devices and does not completely eliminate the underlying tiering logic.
- D. Incorrect.
Incorrect: ESA requires hardware that is specifically certified for ESA compatibility, not just general vSphere certification.
