The Best Damn Windows Server 2003 Book Period- P25

The Best Damn Windows Server 2003 Book Period- P25:The latest incarnation of Microsoft’s server product,Windows Server 2003, brings many new features and improvements that make the network administrator’s job easier.This chapter will briefly summarize what’s new in 2003 and introduce you to the four members of the Windows Server 2003 family: the Web Edition, the Standard Edition, the Enterprise Edition, and the Datacenter Edition. | 206 Chapter 6 Implementing Windows Cluster Services and Network Load Balancing Compatibility List Microsoft s position since it first began publishing cluster technology is that the hardware components used in a server cluster and the entire server cluster configuration itself must be listed on the Hardware Compatibility List HCL in order to receive support. With the introduction of Windows XP Microsoft changed from the HCL to the Windows Catalog. Windows Server 2003-compatible hardware is listed in the Windows Server Catalog but the concept and support requirements remain the same as they were with the HCL. In order to receive technical support from Microsoft ensure that your entire hardware configuration is listed as compatible in the Windows Server Catalog. Using unlisted hardware does not mean you cannot make the hardware work it simply means that you cannot call Microsoft for help if the need arises. Network Interface Controllers A server cluster requires at least two network interfaces to function one for the public network where client requests come from and one for the private interconnect network for the heartbeat . Since a single private interconnect would present a single point of failure it is good practice to have at least two interconnects. Do not use a teamed configuration with interconnects. A teamed configuration binds two or more physical interfaces together into one logical interface. Using teamed controllers preserves the single point of failure. Network controllers should be identical. This includes not only the manufacturer and model but also the firmware and drivers. Using identical controllers will also simplify the design of your server cluster and make troubleshooting easier. Change the default name of each network interface to a descriptive name. Use Heartbeat Interconnect or Private for the interconnect interface. Similarly use Public Primary or some similar name for the public interfaces.You should configure these names identically on .
