2V0-21.23 Question 8
Single answerA VMware administrator is tasked with deploying a virtualized database application that requires high performance and low latency storage. The administrator has access to various storage technologies, including VMFS, NFS, vSAN, and Virtual Volumes (vVols). Which storage technology should the administrator choose to meet the application's requirements?
- A
VMFS with traditional spinning disks
- B
NFS datastore on a high-speed network
- C
vSAN configured with an all-flash disk group
- D
vVols backed by an all-flash array
Show answer and explanation
Correct answer: C
Explanation
vSAN configured with an all-flash disk group is the most suitable option for a database application requiring high performance and low latency. All-flash vSAN clusters leverage SSDs for both caching and capacity, ensuring minimal latency and maximum throughput. While NFS and vVols can also provide good performance, they do not inherently guarantee the same level of consistent low latency as vSAN with all-flash disks.
- A. Incorrect.
VMFS with traditional spinning disks may not meet the performance and low latency requirements due to the limitations of spinning disks in terms of IOPS and latency.
- B. Incorrect.
NFS datastore on a high-speed network can offer decent performance, but it may not provide the consistent low latency required for high-performance database applications.
- C. Correct.
vSAN configured with an all-flash disk group is designed to deliver high performance and low latency, making it an ideal choice for applications requiring these characteristics.
- D. Incorrect.
vVols backed by an all-flash array can provide excellent performance, but the benefits of vVols are more aligned with simplified management and granular storage policy control rather than raw performance.
