Multiple Adapters - Allied Telesis AT-2450 Series Installation Manual

Network Adapter Card Installation Guide - Book II

Multiple Adapters

If a system has multiple Allied Telesyn Ethernet Adapters, you use the
keyword SLOT to identify each card to the driver. If you have multiple
adapters in a single server, each adapter must have a different network
number and SLOT number. Also, you might want to name each adapter.
So add the options in LOAD commands to distinguish particular
adapters. For example:
LOAD <DRIVER> FRAME=Ethernet_802.2 NAME=LAN_A SLOT=1
BIND IPX TO LAN_A NET=11
LOAD <DRIVER> FRAME=Ethernet_802.2 NAME=LAN_B SLOT=2
BIND IPX TO LAN_B NET=22
<DRIVER> is the filename of the adapter driver.
Add the load and bind statements you need to the server's
AUTOEXEC.NCF file so that the Allied Telesyn adapter drivers load
automatically each time the server starts.
In an IPX internal router configuration (a server with two adapters, each
connected to a different network), the data transfer rate across the
router can be low. This happens if client workstations have CPU speeds
equal to or higher than the server. You might be able to increase the
data transfer rate by adding the following line to STARTUP.NCF:
SET MAXIMUM INTERRUPT EVENTS = 100000
The default setting is 10.
If you have problems loading the driver on multiple adapters and the
initialization fails due to "Insufficient RCBs," increase the number of
buffers allocated to the server. Add the following to STARTUP.NCF:
SET MINIMUM PACKET RECEIVE BUFFERS = 100 (or larger)
SET MAXIMUM PACKET RECEIVE BUFFERS = 500 (or larger)
The MINIMUM value you specify must be at least 30 times the number of
Allied Telesyn PCI adapters in the computer.
Recommended settings:
1-3 adapters: 100
4 adapters: 150
The maximum you can specify depends on the amount of memory in
the server, but it must be greater than the minimum.
