Planning a Reliable Configuration
Planning a Reliable Configuration |
|
If users cannot connect to the computers in a configuration that is running Windows 2000 Server, that configuration is not fault tolerant. You need to consider what can fail in the connections between computers as well as within an individual computer.
If your company is growing, the connections between the computers that make up your configuration could become saturated with network traffic. It is recommended that you evaluate network traffic regularly to determine your need to upgrade by adding equipment. You can also use newer technologies, such as ATM, Fast Ethernet 100 BaseT, or GB Ethernet.
Devices that connect different segments of your network, such as routers, bridges, hubs, and switches can also cause bottlenecks and failures. Intermediary devices need to be protected with a UPS.
Determine the level of vendor support available for each device, as well as the standards supported by each device, and whether the vendor has a migration path for new standards. You also need to find out if there are frequent software changes.
If you lease an X.25 connection, an Integrated Services Digital Network (ISDN), Asymmetric Digital Subscriber Line (ADSL), or T1 line to connect to another building, branch, or subsidiary of your company, verify that your line vendor has adequate recovery procedures in place.
