Why switch disks? Why not just install the Teradata demo onto the machine in the first place?

I am confused about what you mean by the new computer has the same name and IP address as the old one. This information is stored in the windows registry, so obviously if you move the disk from one machine to the other it will get the same network configuration !

That is unless there are two disks in the other machine (one containing windows and the other containing the Teradata demo). In that case, there might be some dll's or whatever that need to be in the windows system directory. One thing that immediately comes to mind is entries in the hosts file (which could account for your unreachable message if they are missing).

If there is only one disk in the new computer, are you sure the two h/w environments are identical - presumably the answer is no because at least the processor is different. If there are differences in the h/w there might be something else that is not working quite right that impacts the Teradata demo.

If I were you, I wouldn't waste any time stuffing around with it. Simply install windows and Teradata demo on the disk of your choice in the test machine. Who knows what else might not be set up quite right and cause you grief further down the track.

On a different topic, the installation process should tell you that the demo version of Teradata is not optimised for performance, so I'm not sure what you are expecting to see by putting it on machine with a faster processor. Obviously CPU intensive operations should run faster, but overall you might not see much difference.

Certainly you shouldn't be putting much weight on any benchmarks you do with this version.

In the demo version you want see any of the benefits obtained in the production version for example:

* Multiple CPU's sharing the processing load

* Multiple I/O paths to increase the i/o date transfer rates.

* Raw partitions - that eliminate overheads incurred from the Windows File Systems (eg NTFS, FAT 32 etc)

* etc

The purpose of the demo is to look at the capabilities of Teradata - not evaluate the performance.

I hope this helps
