Dual TCP/IP Configuration Examples

StorageTek SL3000 Library Guide
–
Provide dedicated bandwidth between the host and library.
–
Create a virtual local area network (VLAN) between the host and library.
■
Use a virtual private network (VPN) to insulate host-to-library traffic from other
interference, such as irrelevant broadcasts.
Network Broadcast Issues on a Shared Network
Broadcasts sent to all network nodes may be directed to the library. The library cannot
efficiently process requests while it is receiving these irrelevant broadcasts. As a result,
the host may determine the connection to the library is lost.
Heavy network traffic can also overwhelm the Ethernet controller on the HBC/HBCR
card. As a result, the controller continuously resets.
ARP Floods on a Shared Network
The SL3000’s processor can be overwhelmed by floods of address resolution protocol
(ARP) broadcasts. You should connect the library behind a switch or router.

ACSLS Dual TCP/IP and Shared Subnets Example
In this example, the ACSLS server and the library share two separate subnets. The
SL3000 uses a one-to-one relationship with the network interfaces on the ACSLS
server. The network interface card on subnet 192.168.0/23 connects to port 2B and the
network interface card on subnet 192.168.1/23 connects to port 2A.
Routing
Force a relationship by using the UNIX
route
commands. For more information, see
the
ACSLS Administrator's Guide
and
SL3000 Installation Manual
.

ACSLS Dual TCP/IP Through a Public Network Example
In this example, the ACSLS server contains two network interfaces that reside on two
separate subnets. Both interfaces pass through a public network and into two different
