Critics of the XIV have often argued that performance and availability weaknesses meant that this platform was not viable as a “Tier 1” system. User experiences contradict such claims.

In a separate survey of 63 XIV users, more than 60 percent reported that XIV systems supported one or more Tier 1 applications. Organizations ranged from midsize businesses to Financial Times Global 50 companies. XIV systems also supported Tier 2 and Tier 3 applications, and 25 percent reported leveraging XIV single-tier architecture to consolidate storage platforms.
