Question
When the VxRail cluster is deployed, what are the vSAN storage policy settings that are applied to the VxRail Manager VM?
A. Failures to Tolerate: 2 failures – RAID-6 (Erasure Coding) Object space reservation: Thin provisioning
B. Failures to Tolerate: 1 failure – RAID-1 (Mirroring) Object space reservation: Thick provisioning
C. Failures to Tolerate: 1 failure – RAID-5 (Erasure Coding) Object space reservation: Thick provisioning
D. Failures to Tolerate: 1 failure – RAID-1 (Mirroring) Object space reservation: Thin provisioning
Answer
A. Failures to Tolerate: 2 failures – RAID-6 (Erasure Coding) Object space reservation: Thin provisioning
Explanation
The correct answer is A. Failures to Tolerate: 2 failures – RAID-6 (Erasure Coding) Object space reservation: Thin provisioning.
When a VxRail cluster is deployed, the VxRail Manager VM is automatically created and assigned to a storage policy with the following settings:
- Failures to Tolerate: 2
- RAID Level: RAID-6 (Erasure Coding)
- Object Space Reservation: Thin Provisioning
These settings provide a high level of availability and performance for the VxRail Manager VM.
Here is a more detailed explanation of each setting:
- Failures to Tolerate (FTT): This setting determines how many failures the VxRail Manager VM can tolerate before it becomes unavailable. A setting of 2 means that the VM can tolerate the loss of 2 nodes in the cluster before it becomes unavailable.
- RAID Level: This setting determines how the data for the VxRail Manager VM is stored on the vSAN datastore. A RAID-6 level provides fault tolerance by distributing the data across multiple disks and encodng it with parity bits.
- Object Space Reservation: This setting determines how much space is reserved for the VxRail Manager VM on the vSAN datastore. A thin provisioning setting means that the VM only uses the space that it actually needs.
These settings can be modified for the VxRail Manager VM if necessary. However, it is important to note that modifying these settings may impact the availability or performance of the VM.
