Brocade also produces HBA (Host Bus Adapters) cards which we install on servers to have connectivity option/ports.
Thus generally, EMC and NetApp (and IBM, Hitachi, HP etc...)produces storage devices where the actual data is getting saved.They also produces software to manage/monitor the hardware. Brocade (and Cisco, Qlogic, Emulex etc...) gives connectivity options (including SAN switches and HBA cards)
