Dell PowerFlex 4.5.x Technical Overview
PowerFlex overview
PowerFlex is an enterprise-class, software-defined block and file storage solution that is deployed, managed, and supported as a single system. Highly flexible and scalable, PowerFlex allows customers to have a mixture of two-layer (server SAN), single-layer hyperconverged configurations, storage-only, PowerFlex file services, and other mixed architectures within a single deployment.
With PowerFlex, resources such as storage and compute can be scaled together or separately, non-disruptively, and in small increments. The system can scale from a few nodes to hundreds in a cluster, linearly scaling I/O performance and throughput. In addition, PowerFlex supports a broad set of operating environments that include multiple hypervisors, bare-metal operating systems, container management tools, and PowerFlex file services capabilities (NFS, CIFS, and additional file services offerings). This allows customers to flexibly transition application architectures, while supporting multiple generations of applications with disparate architectures in a single system.
PowerFlex offers integrated product options. PowerFlex appliance is a scalable system with flexible form factors that comes pre-configured and validated for fast, easy deployment. PowerFlex rack is a rack-scale system that is manufactured, managed, supported, and sustained as one system for single-end-to-end lifecycle support. PowerFlex custom node is a validated engineering solution that provides nearly all the flexibility of the PowerFlex software offering.
