I'm going to expand on this a bit more. Teradata installations are finely balanced between the CPU, memory, interconnect bandwidth, DASD connect bandwidth and DASD I/O throughput. In essence, a well tuned (normal) Teradata installation will not be constrained on any of these components. This being true, the underlying OS and the underlying CPU architecture have little effect on the performance of the system. Rather, they have an effect on the COST of the entire solution platform.

From the mainframe, all one really sees is the performance of the SQL and batch maintenance jobs (both fully parallelized) submitted across the channel. One does not see UNIX, NT, Solaris, 32-bit, 64-bit, or whatever.

AFAIK, Intel has two hardware teams: the 32-bit team and the 64-bit team. They are very competitive. One can expect that both chip teams will compete with each other going forward a few more years.

Once the performance and cost advantages for the 64-bit Intel chip start to become apparent, Teradata will have a fully productionalized release on that platform, using Solaris for Intel. Teradata will also carry forward with the 32-bit platform for a number of years.

BTW: this information was presented at the Teradata Partner's conference in Orlando last October.
