The Datastore Sizing Analysis graph shows the number of undersized and oversized Datastores. The X-axis of the graph is divided into two groups: Oversized and Undersized.
SHO determines whether a Datastore is undersized or oversized based on the thresholds set on the Thresholds tab of the Configurations View page. For more information, see Defining Thresholds.
