QuestionQ26

PowerScale Implementation

A customer is upgrading their PowerScale system and wants a shorter maintenance window without introducing service outages. Which upgrade method is recommended?

Explanation

Parallel upgrades restart only subsets of nodes at a time while the remaining nodes stay online to serve clients. Dell recommends this method because it requires a smaller maintenance window than rolling upgrades and does not require the service interruption of simultaneous upgrades.
