PowerStore can be configured with a minimum of six drives in the base enclosure. Storage pools on PowerStore 1200T through 9200T models can be expanded up to 100 drives through expansion enclosures. The total disk capacity does not automatically guarantee disk performance. There must be enough drives to meet I/O and capacity demands. Base enclosure front-end ports can also be expanded.
If horizontal scaling is a design requirement, PowerStore models support a scale-out configuration with one to four appliances in a single cluster. Contact your Dell Technologies representatives for assistance with sizing a PowerStore solution.
