DELL TECHNOLOGIESDell VxRail Design
The Dell VxRail Design certification validates your expertise in translating customer needs into high-performing, resilient VxRail solutions. You’ll demonstrate skills in workload assessment, capacity planning, and using tools like Live Optics, VxRail Sizer, and EIPT to design optimized compute, storage, network, and environmental configurations. It also highlights designing for resilience, including data protection, high availability, and disaster recovery aligned to RPO/RTO goals. The certification further proves your ability to create clear design documentation, validate solutions, present architectural decisions, and configure systems using the VxRail Configuration Portal, positioning you as a trusted expert in delivering scalable, business-aligned solutions.
