A PowerFlex appliance two-layer deployment has a base configuration that is similar to a PowerFlex storage-only node deployment, but adds a minimum set of PowerFlex compute-only nodes. The minimum set of PowerFlex storage-only nodes and fixed network resources are also required.
Within the base configuration, you can customize the following hardware aspects:
Hardware | Minimum set |
---|---|
Compute | At least three PowerFlex compute-only nodes. |
Network |
|
Storage | At least four
PowerFlex storage-only nodes are required. However, Dell Technologies recommends using at least six nodes to build a
PowerFlex storage pool.
Software-defined SAN storage (uses local disks to build a PowerFlex storage pool). If storage compression is active, two SDPM components (for PowerFlex R660 or PowerFlex R760) or a minimum of two NVDIMM components (for PowerFlex R650 or PowerFlex R750) per PowerFlex node are required. A recommendation is made according to the system sizing calculation. |
Management | Standalone or multi-node PowerFlex management controller with high availability or customer provided management infrastructure. |
