IBM Communications Server for AIX, V6 New Features and Implementation Scenarios

142 IBM Communications Server for AIX, V6: New Features and Implementation Scenarios

The previous figure shows an ESCON director between the host and the AIX

system. However, an ESCON director is not required. Up to two ESCON

directors may be used to extend the distance between the host and AIX

system up to 43 kilometers.

MPC+ links require HPR and support only independent LUs. Therefore, if

dependent LU (LU0, 1, 2, 3) support is required over an MPC+ link,

DLUR/DLUS must be used.

The overall CS/AIX support for channel connectivity is referred to as the

SNA

Channel for AIX

feature. Support for MPC+ connectivity is part of the SNA

Channel for AIX feature. See the IBM

Communications Server for AIX

Channel Connectivity User’s Guide

, SC31-8219 for detailed information on all

the channel connectivity options supported by CS/AIX V6.
