2V0-21.23 Question 76
Select 3A company is planning to deploy VMware vSAN as its primary storage solution for a new vSphere environment. The IT team wants to ensure that they understand the key features of vSAN before implementation. Which of the following statements accurately describe VMware vSAN?
- A
VMware vSAN requires a dedicated storage network separate from the vSphere management network.
- B
VMware vSAN uses disk groups that combine SSDs for caching and HDDs or SSDs for capacity.
- C
VMware vSAN provides storage policies that allow administrators to define performance and availability on a per-VM basis.
- D
VMware vSAN requires an external storage array to function as its primary data repository.
- E
VMware vSAN integrates directly with the hypervisor to eliminate the need for a storage appliance.
Show answer and explanation
Correct answers: B, C, E
Explanation
VMware vSAN is a software-defined storage solution that is tightly integrated with the ESXi hypervisor. It uses local disks from ESXi hosts, forming a shared datastore across the cluster. Disk groups in vSAN consist of SSDs for caching and either SSDs or HDDs for capacity. Additionally, vSAN offers flexible storage policies to define performance and availability at a granular level. It does not require external storage arrays or a dedicated storage appliance, making it a cost-effective and efficient solution.
- A. Incorrect.
Incorrect: VMware vSAN does not require a dedicated storage network; it can use the existing vSphere management or vMotion network, though a dedicated network for vSAN traffic is recommended for performance.
- B. Correct.
Correct: VMware vSAN uses disk groups that consist of SSDs for caching and either HDDs or SSDs for capacity, depending on the configuration.
- C. Correct.
Correct: VMware vSAN provides storage policies that enable administrators to define characteristics such as performance, redundancy, and availability on a per-VM basis.
- D. Incorrect.
Incorrect: VMware vSAN does not require an external storage array; it is a software-defined storage solution that uses the local disks of ESXi hosts in a cluster.
- E. Correct.
Correct: VMware vSAN is integrated directly into the ESXi hypervisor, eliminating the need for a separate storage appliance.
