Clustering on Windows 2003
Posted on 2004-11-02
Here is my sisutuation , I currently have a Windows 2003 SE server which is the main server in my organization. I also have a newly deployed Exchange Server 2003 running on Windows 2003 EE. I also have a 2000 Server that is not doin anything. My plan is to upgrade that server to 2003 EE as well as my main server, and implement a 3 node cluster using the old server as the common media device as it is my undeerstaing that you have to have one in order to utilize clustering. Several question I have regarding clustering are:
1) In the event of a server going down will clustering allow me to utilize that third server to run my apps in the interim?
2) What kind of Software will have to be installed on that common media device? I asume 2003 EE, but do I need to have a separate set of CAL's for it even though it would only be used in the event of an emergency?
3) Do I need to install all of the apps that I would like it to run in the event one of my main servers (Exchange & File server) goes down?
I have had several vendors come in and pitch software such as Legato to me, but if clustering can perofrm all of these functions without using a third party app then I am inclined to go with that as the solution. Your feedback is greatly appreciated.
