QuestionQ23

Analyze and Optimize Storage Performance

A Nutanix cluster is deployed with the following configuration:

  • Three four-node blocks: A, B, and C
  • All Flash Redundancy Factor 2

What is the impact of simultaneous disk failures on two nodes in block A?

  • A VMs are migrated of the nodes with disk failures.
  • B Each node with a failed disk is marked as degraded.
  • C VM read and write operations continue normally.
  • D VMs on the nodes with failed disks are unable to write data
Explanation

RF2 block awareness distributes redundant data copies across separate blocks when at least three blocks are available. Therefore, two disk failures confined to block A do not remove both copies of VM data, and VM read and write I/O continues normally.
