In all-flash arrays (AFAs), architectural design choices can have a major impact on the quality of the enterprise storage life-cycle experience. Pure Storage, a leading vendor in terms of enterprise-class AFA revenue, changed the industry forever with the introduction of its Evergreen Storage program back in 2015.

This white paper takes a closer look at FlashArray's architectural support for the Evergreen Storage program, delving into four very specific areas: software-driven architecture, stateless controllers, modularity of components, and simplicity of design. Real customer benefits — whether in terms of better performance, higher availability, easier deployment and management, improved efficiencies, nondisruptive multigenerational technology refresh, and/or lower costs — result from these architectural choices. These benefits are also a key factor in Pure Storage's industry-leading Net Promoter Score, an objective third-party metric that measures the quality of the overall customer experience (CX).
