Talk:Tandem Computers

message: The whole article is almost entirely just the past history of Tandem, which is understandable, but it should have a section about the present.  Ratbert42 02:37, 20 July 2006 (UTC)

thread_title: failure rate of other systems

message: The following sentence from this article is COMPLETELY false and erroneous:
Over the two decades from the 1970s into the mid-90s, Tandem systems evolved into software-only solutions running on other platforms. 
Tandem systems CANNOT be implemented to run on other platforms.  They can be implemented using commodity microprocessors -- and much cooperation with INTEL has led to the inclusion at the hardware level of key features necessary to use Itanium Processors in Tandem systems.
HP NonStop Servers are the ONLY hardware platform able to support the NonStop Kernel Operating System (formerly known as Guardian).
FYI, Jay Van Dwingelen, former employee of Tandem Computers for 21+ years.  — Preceding unsigned comment added by 24.107.147.63 (talk • contribs) 23:06, 15 August 2003 (UTC)
thread_title: software-only

message: I recall that in the beginning HP refused the nonstop-fault-tolerant concept and that is why the engineers left HP to startup Tandem.
If this is true, this should be inserted into the article.
Also mention of competitors in this area would be nice, Sequent, Stratus, IBM...others?
The article also mentions that, Himalaya  and S-Series are the same... I thought
they were different systems.

They are different.  Himalaya used a Bus type architecture.  S-Series utilizes ServerNet Art Rice 14:51, 27 August 2009 (UTC)

message: (part of the previous section)
Yes, this is true.  I'm a little hazy about the details, but in the early 70s an HP team did a proposal for a Dutch company for a more robust system than HP's current offerings.  The people involved were Horst Enzelmueller, Josef Broeker and [damn! I've forgotten his name, just remember his face] (it was Jürgen Krüper, CW), all from HP in Frankfurt, Germany.  They later became the CEO, software support manager and hardware support manager for Tandem Computers Germany, thus explaining why Germany was the first place outside the USA to have a Tandem subsidiary.  My recollection, which I'll research, is that HP wasn't interested in their idea, so along with colleagues in the USA, notably Jimmy Treybig and Dave Mackie, they developed their own architecture and company.

message: The information on this page is very inaccurate.  The Integrity series was originally a competitive offering to the T/16 architecture, developed in Austin TX, and it ran a version of MIPS UNIX.  The first product was the S2 in 1989.  Some time in the mid-90s they ported Guardian (sorry, NSK) to the hardware and introduced the S7000.  The S4000 carried on with UNIX.
All this is off the top of my head, so I'm putting it here rather than in the main article.  If anybody wants to build on it, feel free.  Groogle 05:59, 23 February 2007 (UTC)
replies: text: The article said Integity was introduced in 1990, so I've changed that to 1989.  Otherwise, I don't see inaccuracies; the article fits with what you've written above, although with slightly less detail. -R. S. Shaw 19:02, 23 February 2007 (UTC)

message: Might be nice to add something about the famous 1992 CLX clock crash.  Starting in New Zealand all CLX machines started to crash as 3 p.m on November 1, 1992 rolled around the world.  Tandem struggled to find the cause, eventually discovering and fixing a microcode bug before the crash reached the European time zone.  ref http://www.csl.sri.com/users/neumann/cal.html HughesJohn (talk) 12:48, 1 November 2008 (UTC)

message: Added an Ri tag since this article has next to nothing for references. I did dig up the old Tandem website on the Wayback Machine at http://web.archive.org/web/19961230182819/http://www.tandem.com/ which might be a start to at least referencing the systems.

message: Not that it belongs in the story, but having worked at Tandem HQ in 87-88, I recall that the TGIF's restaurant next door to the HQ (across from Vallco Fashion Park Mall) started offering "NonStop® Fajitas"... essentially, unlimited fajitas for a fixed price.  I thought it very clever of them. -- Randal L. Schwartz (talk) 04:11, 28 August 2010 (UTC)

message: The "Culture" section is rather lengthy for an encyclopedic article and has some neutrality issues. It could probably be shortened a bit as well. Bumm13 (talk) 04:07, 15 September 2013 (UTC)

message: My edit of 2016-08-08 got reverted.  I understand the comment that was made on the reversion, which means that I shouldn't have used the word "components".  However, as previously written (and now, as reverted), the sentence doesn't seem grammatical to me.  It says '... toughened systems that used redundant but usually required "hot spares".'  Used redundant *what*?
I guess there is a possible interpretation in which "but usually required" as an adjectival phrase, so the meaning it "toughened systems that used hot spares that were redundant but usually required".  However, if this is the meaning, it's extremely clunky, and I would argue that the sentence needs to be rewritten.  As a minimum, some commas would be useful: '... toughened systems that used redundant, but usually required, "hot spares".'  But I don<t want to make this change, because I'm not sure if this is what is meant, or if there is simply a word missing where I had inserted "components".

There are no sources for that subsection, I figured this will due. Feel free to correct me though.
