2V0-21.23 Question 7
Single answerA VMware administrator is designing a storage solution for a vSphere environment with high-performance requirements. The environment will host virtual machines with applications that require low latency and high IOPS. Which storage technology would best meet the requirements for this workload?
- A
NFS Datastore
- B
vSAN with All-Flash Configuration
- C
VMFS Datastore on HDD-based Storage
- D
vSAN with Hybrid Configuration
Show answer and explanation
Correct answer: B
Explanation
For environments with high-performance requirements, vSAN with an all-flash configuration is the ideal choice. It leverages SSDs for both caching and capacity, providing low latency and high IOPS. Other options, such as NFS or hybrid vSAN configurations, may not meet the same performance criteria, especially for workloads with stringent latency and IOPS demands.
- A. Incorrect.
NFS Datastore provides shared storage and flexibility, but it may not deliver the highest performance and low latency required for workloads with high IOPS demands.
- B. Correct.
vSAN with All-Flash Configuration is designed to provide low latency and high IOPS, making it the best option for high-performance workloads. It uses SSDs for both caching and capacity, optimizing performance.
- C. Incorrect.
VMFS Datastore on HDD-based Storage is cost-effective but does not provide the low latency or high IOPS required for high-performance applications. HDDs have higher latency and lower performance compared to flash storage.
- D. Incorrect.
vSAN with Hybrid Configuration uses SSDs for caching and HDDs for capacity, which can provide decent performance but is not as optimal as an all-flash configuration for high IOPS and low latency workloads.
