To take account of the high quality demands of SAN infrastructures, data transport between these SAN islands is accomplished via interswitch links, in other words, high performance optical fibre channel connections.
In conjunction with the need for confidentiality in the transmission of data over the two highspeed links to the data processing centre, Valartis looked for a solution that could not only provide encryption for the SAN but also for the LAN traffic.
In order to meet the required security target the data links between the two processing centres are protected by InfoGuard MG10 hardware encryption devices. Three 1 Gigabit Ethernet and a 2 and 4 Gigabit Fibre Channel link are multiplexed on a 10 Gigabit signal, encrypted and transmitted over the dark fibre cable. Taking account of redundancy, therefore, two pairs of InfoGuard MG10 devices are in operation.
