PowerFlex network layer supports multiple topologies and multiple bandwidths. The network topology showed in the Dell OAS solution insight architecture uses dual 25GbE top-of-rack switches and four 25GbE network links/ports per SDC (CO and File nodes), SDS, and management controller nodes to carry the intranet data traffic for the web, application, and database tiers. All PowerFlex nodes also use dedicated, redundant 1 GbE links/ports to connect to a dual out-of-band management switch for all management needs.
