Ch 4: Networking Explaineds The Public Network (Ethernet Rails) A pair of network cards, one in each IOP, in the same PCI slot numbers constitutes a "public rail." There are several different terminologies used for essentially the same network type. For the network cards that the IOPs use to intercept client traffic on the network, these cards may be referred to as the public network, a public rail, or an Ethernet rail. As far as the requirements for the AA 4000 software go in regards to the network cards to be used as the public network, any NDIS 4 compliant network card with Windows NT 4.0 drivers will work. These cards also must support the capability of having their MAC addresses "soft-set" by the Marathon software into the NT registry. This is part of NDIS 4 standards, so any of these network cards should comply. For the purposes of the HPAA system, the public network cards will also be HP 10/100 TX cards. Network Server Division Additional public rails can be added to the array. Up to four public rails, or four pairs of NICs, can be added to the IOPs in addition to the IOP link. For a NetServer LH 3, the five network cards would be inserted into PCI slots 2 - 6 with slot 6 functioning as the private link. Each public rail as represented by the pair of NICs is constantly "listening" on the network wire for its destination server MAC. For the purposes of client access, there is only one NetBIOS server name for the array, as defined in the CE, and only one IP address per public rail (multiple IP addresses can be assigned to a the virtual network adapter the same as any other NIC in a standard copy of Windows NT). Both NICs in the rail are listening and prepared to pass traffic to the CEs, but only the NIC that is currently online will actually pass the traffic. The other NIC will begin to pass the traffic 4-7
