Which three topics would impact this design?

An administrator needs to design a new vSAN cluster to host production mission critical workloads.

Which three topics would impact this design? (Choose three.)

A. The amount of ESXi host memory

B. Effective vSAN datastore capacity

C. The amount of virtual Disks per VM

D. The size of the cache tier according to workload characteristics

E. The supported CPU type of the ESXi host

F. Usage of vSphere DRS

Answer: A,B,D

Explanation:

When designing a vSAN cluster for mission-critical workloads, various factors must be considered. These three topics would significantly impact this design:

A. The amount of ESXi host memory: Memory is a critical resource for running virtual machines and for the overall performance of the vSAN cluster. Lack of sufficient memory can severely impact the performance of the hosted VMs.

B. Effective vSAN datastore capacity: The capacity of the vSAN datastore is crucial, as it determines how many VMs and data can be stored on the cluster. Insufficient datastore capacity can lead to a lack of storage space for VMs, impacting scalability and operations.

D. The size of the cache tier according to workload characteristics: The cache tier is crucial for vSAN performance. It acts as a buffer for the storage traffic and can improve performance significantly, especially for workloads with high IO requirements. The size and type (read-intensive, write-intensive, or mixed-use) of cache should be determined based on the workload characteristics.

The amount of virtual disks per VM (C), the supported CPU type of the ESXi host (E), and usage of vSphere DRS (F) can have implications, but these factors are generally less direct in their impact on the vSAN cluster design for mission-critical workloads.
