Siemens V4.0 Planning for Wins Server Performance, Planning for Replication Convergence Time

Implementing WINS Planning for WINS Server Implementation

10.2.2.1Planning for Replication Convergence Time

The time needed to replicate a new entry in a WINS database from the WINS server that owns the entry to all other WINS servers on the network is called convergence time. When planning for WINS servers, you need to decide the acceptable convergence time for your network.

For information about convergence time, see the Microsoft Windows NT Resource Kit Networking Guide.

10.2.2.2Planning for WINS Server Fault Tolerance

The two basic types of WINS server failures are as follows:

●A WINS server can crash or be stopped to perform maintenance.

●Network failures, including failures of routers and link stations.

For information about WINS server fault tolerance, see the Microsoft Windows NT Resource

Kit Networking Guide.

10.2.3 Planning for WINS Server Performance

When planning for a large-scale power outage where many computers will go on line simul- taneously, the conservative recommendation is that you plan to include one WINS server and a backup server for every 10,000 computers on the network.

The maximum rate at which a WINS Server can handle registrations and queries depends almost solely on the CPU performance, as long as the media bandwidth is clearly below saturation. Adding more CPUs to an Advanced Server computer running the WINS service does not improve this maximum rate, since the service is implemented within one UNIX process. WINS server replication response time can be improved measurably by placing the WINS database files on a less utilized disk.

After you establish WINS servers on an intranet, you can adjust the time between a WINS client name registration and name renewal. This is referred to as the Renewal Interval. Setting this interval to reduce the numbers of registrations can help tune server response time. (The Renewal Interval is specified in the WINS Server Configuration dialog box.)

i

The default value for the renewal interval (6 days) has been choosen with care! You should not configure shorter renewal intervals unless you have specific reasons to do so.
