Question

A 100GB virtual disk object has this storage policy assigned to it:

  • Site disaster tolerance: None - standard cluster
  • Failures To Tolerate: 1 failure - RAID-1 (Mirroring)
  • Number of disk stripes per object: 3

What is the maximum amount of raw vSAN storage capacity consumed by this virtual disk?

Options

  • A100GB
  • B200GB
  • C300GB
  • D600GB

Explanation

With a RAID-1 (Mirroring) policy and Failures To Tolerate = 1, vSAN creates two full copies of the object for redundancy, effectively doubling the storage consumption. The number of disk stripes per object (3) only affects how each replica is distributed across capacity devices, not the total Thus, a 100GB virtual disk with RAID-1 FTT=1 consumes 2 × 100GB = 200GB of raw vSAN
