2V0-21.23 Question 26
Single answerAn administrator is designing a storage solution for a virtual environment using VMware vSAN and VMware Virtual Volumes (vVOLs). The environment requires tight integration with storage policies, support for dynamic scaling of storage, and the ability to leverage existing external storage arrays. Which storage approach should the administrator choose?
- A
VMware vSAN, as it provides native integration with storage policies and dynamic scaling of storage.
- B
VMware vVOLs, as it integrates with external storage arrays and allows policy-based management.
- C
VMware vSAN, as it supports external storage arrays and integrates with storage policies.
- D
VMware vVOLs, as it is specifically designed for hyper-converged infrastructure.
Show answer and explanation
Correct answer: B
Explanation
VMware Virtual Volumes (vVOLs) are ideal for environments requiring integration with existing external storage arrays. vVOLs enable policy-based management through vSphere Storage Policy-Based Management (SPBM) and allow dynamic provisioning and scaling of storage resources. VMware vSAN, on the other hand, is a hyper-converged storage solution designed to use local storage resources and does not integrate with external storage arrays.
- A. Incorrect.
VMware vSAN does provide native integration with storage policies and dynamic scaling of storage, but it does not leverage external storage arrays. Instead, it is a hyper-converged solution that uses local storage.
- B. Correct.
VMware vVOLs integrate seamlessly with external storage arrays and provide policy-based management through the vSphere Storage Policy-Based Management (SPBM) framework, making it the correct choice.
- C. Incorrect.
While VMware vSAN integrates with storage policies, it does not support external storage arrays. It is designed for hyper-converged storage using local disks in ESXi hosts.
- D. Incorrect.
VMware vVOLs are not specifically designed for hyper-converged infrastructure. Instead, they are designed to provide integration with external storage arrays and policy-based management.
