Increase Performance in Cache Miss Situation

B.

When using vSAN, Storage Policies are used to define the storage requirements of virtual machines and their virtual disks. These policies specify the number of replicas, RAID protection, and other storage characteristics of the vSAN datastore.

In a cache miss situation, where the requested data is not present in the cache and needs to be fetched from the underlying storage, the performance of vSAN can be improved by increasing the number of disk stripes per object.

Disk striping is the process of dividing data into small blocks and storing them across multiple disks in a storage pool. By doing so, disk striping can improve read and write performance by allowing multiple disks to work in parallel to access the same data.

Increasing the number of disk stripes per object in vSAN Storage Policies can improve performance in a cache miss situation by allowing vSAN to retrieve more data in parallel from the underlying storage. However, it's worth noting that increasing the number of stripes also increases the amount of storage required to store the data.

Therefore, option B - Number of disk stripes per object, is the correct answer. Option A (Number of failures to tolerate) and Option D (Object space reservation (%)) are not related to improving performance in a cache miss situation, and Option C (Force provisioning) is related to the process of provisioning storage resources and not related to improving performance in a cache miss situation.
