PowerFlex rack has a base configuration that is a minimum set of hyperconverged components and fixed network resources.
Within the base configuration, you can customize the following hardware aspects:
| Hardware | Minimum set |
| Compute and storage | A minimum of four PowerFlex hyperconverged nodes are required, however six is the recommended minimum. PowerFlex hyperconverged nodes provide both storage and compute resources to the system. If storage compression is active, a minimum of two NVDIMM components per PowerFlex node are required. A recommendation is made according to the system sizing calculation. |
| Network |
|
| Management | Three PowerFlex management controller nodes with high availability. |
PowerFlex rack is a scale-out solution that enables you to add PowerFlex rack nodes with various CPU, memory, and drive options.
PowerFlex software-defined SAN storage enables scaling from a base configuration to a large-scale deployment.
Together, the components offer balanced CPU, I/O bandwidth, and storage capacity relative to the compute and storage arrays in the PowerFlex rack. All components have N+1 redundancy.
These resources can be scaled up as necessary to meet increasingly stringent application workload requirements. To scale up storage or compute resources, add nodes to the environment. Optionally, add expansion cabinets with more resources - this is default for the PowerFlex rack network design.
