Use the datastore Performance tab to monitor how Storage I/O Control handles the I/O workloads of the virtual machines accessing a datastore based on their shares.

Datastore performance charts allow you to monitor the following information:

  • Average latency and aggregated IOPS on the datastore

  • Latency among hosts

  • Queue depth among hosts

  • Read/write IOPS among hosts

  • Read/write latency among virtual machine disks

  • Read/write IOPS among virtual machine disks


Launch the vSphere Client and log in to a vCenter Server system.


  1. Select the datastore in the vSphere Client inventory and click the Performance tab.
  2. From the View drop-down menu, select Performance.

    For more information, see the vSphere Monitoring and Performance documentation.
