Subj:		Re: Teradata OS

From:		David Nasser

Hello again,

<retry>

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.

With all due respect, all computer systems have potential and/or actual bottlenecks. Just hand a system over to a group of users ...

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.

You take the position that performance is independent of the OS?? This po' boy has been trained otherwise.

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.

I'm not really concerned with the mainframe. It is "familiar territory.

Just this week, we had a query blow up, eat 160 gb of spool space. First thing we did was forget the mainframe, test with NT/Queryman. Jury is still out... hope its something silly ...

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.

This sounds reasonable.

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.

Yes, I agree the 32 bit stuff should continue to be largely functional for years to come.

But I find the IA-64/Solaris/Teradata proposal to be troublesome.

Sun, in most ways, is king of the hi-end server market. Its nearly all based on Sparc/UltraSparc Solaris.

I would estimate that about 2% of Sun software revenue comes from Intel Solaris products. I suspect they have been losing $ on Intel Solaris for years.

FWIW, the following is from PCWeek, 2/21/2000, p. 10:

"Intel Showcases New Chips"

" ... software support for 64 bit Itanium chip remains fuzzy."

" ... Intel confirmed it has dropped Sun/Solaris from Itanium marketing materials, with published reports saying Intel felt Sun was not serious about its support of the IA-64 architecture. ..."

Thanks to all for responses to my query.

David
