Gathering Networking Information

Three Independent Networks

4-4
In order to successfully configure the network cards, gather the
following information:
•
MAC addresses
•
PCI Slot location
•
Subnet attached to / planned TCP/IP address
This information will be used to configure the network cards in the
Marathon Configuration Utility and the Windwos NT Network
Propeties.
There are three distinct network types in operation for any
implementation of the HPAA Solution.
The first network setup is the IOP Link or private network. Similar to
a "heartbeat" network link in a clustering environment, this network
is responsible for internal IOP-to-IOP communications and it also
carries disk-mirroring traffic.
The next network type is commonly referred to as a public rail or the
redirected network. Using specific Marathon protocols this network
comes in two parts, the software on the CEs and the
software/hardware implementation on the IOPs. This network is used
for client access.
The last network type is the virtual network. To simplify
maintenance and access to resources, an internal system network is
created for the CEs and IOPs. This provides a mechanism for CEs to
see resources exclusively provided by the IOPs and vice-versa. The
network is "virtual" because it does not consist of network interface
cards. The traffic is carried out by the MICs.
