A customer runs their core application on an aging HPE 3PAR StoreServ 20000 Storage array.

Given that the customer's core application requires 100% availability, the HPE Primera (Option C) is the best storage solution to recommend. HPE Primera is designed for mission-critical applications that demand the highest levels of availability, performance, and resilience. It offers advanced data services, AI-driven predictive analytics, and a 100% availability guarantee, making it the ideal choice for environments where downtime is not an option.

Primera's architecture is built to ensure continuous availability, even in the face of hardware failures or other unexpected issues, which makes it superior to other options like Nimble or MSA for this specific requirement.
