One of the two access modes that can be set for the ESS during initial configuration. It enables all host systems, attached to fibre channel and with no defined access profile, to access all logical volumes (LVOLs) on the ESS. With a profile defined in ESS Specialist for a particular host, that host has access only to volumes that are assigned to the worldwide port name (WWPN) for that host. See also anonymous, anonymous host, EsconNet, FiconNet, worldwide port name.
