Enterprise Data Center Networking Implementation Plan
This bulletin provides a suggested outline of an implementation plan for enterprise data center networking solutions with respect to IBM mainframes. This plan can be customized as necessary for the solutions and migration path that works best for your network. As a starting point, it includes:
•Installing SNA Switching Services (SNASw) with Dependent Logical Unit Requester/Dependent Logical Unit Server (DLUR/DLUS) and enabling it for TN3270 Server
•Migrating Data-Link Switching Plus (DLSw+) in the WAN to SNASw
•Replacing DLSw+ and extending SNASw all the way to the remote branch
•Converting SNA applications to IP
Note: SNASw can be enabled for customers who use Cisco TN3270 Server remote from the data center and those who want a single-protocol, IP path to the mainframe logical partitions (LPARs).
The introduction of SNASw capabilities to an existing network design could follow a plan as outlined in Table 1. The advantage of a plan is to introduce specific network benefits according to a schedule, allowing for proper resource allocation, planning, change control, and configuration and installation. The end result is a simplified data center design, an all-IP consolidated network, and continued support for SNA applications as necessary.
