QuestionQ15

Analyze and Optimize Storage Performance

An administrator is deploying an application that needs maximum I/O throughput for scratch data. The administrator is concerned that the required throughput exceeds what a single cluster node can provide. What should the administrator do to satisfy this requirement?

  • A Create a volume group with several virtual disks and attach to the VM
  • B Create a volume group with one virtual disk attached to the VM
  • C Create a virtual disk attached to the VM's PCI interface
  • D Create several virtual disks attached to the VM's virtual SCSI controller
Explanation

A volume group containing several virtual disks can be load-balanced across the cluster’s Controller VMs, enabling parallel storage I/O beyond the capacity of one node. Nutanix recommends using multiple disks, with at least one per cluster node, to distribute a workload across the cluster and increase throughput.
