From: [EMAIL PROTECTED] (Edward Gould) Subject: HP to compete with S/390 Newsgroups: bit.listserv.ibm-main Date: 12 Sep 2000 13:52:18 -0700 Hewlett-Packard will face the S/390 head on when it unveils today its new Superdome computer in a bid to up its standing in the lucrative Unix server market. HP is expected to position Superdome with a host of "e-services" to appeal to customers wishing to link business operations housed on different servers, something it says IBM is unwilling to do with its Unix servers lest it undermine sales of its S/390 mainframe line. "HP hopes to unseat mainframe with Superdome" http://news.cnet.com/news/0-1003-200-2757613.html?tag=st.ne.1003. ... snip ... pre-itanium part of the issue had been that HP had acquired Convex. Convex had done the scalable Examplar using "64-port" sci memory coherent with two hp pa-risc chips/board (128 chips, processor in numa configuration). my understanding from the hp engineers was that superdome would be somewhat smaller and more efficient (to implement, 32 processors) box that they would move into the (convex) examplar customer segment ... as well as moving out into the more commercial world. also from 9/12/2000 (same as the referenced item). HP thinks big with Superdome servers http://news.com.com/2100-1001-245591.html initially announced with 32 processors but with promise of 64 processors to come soon. also promised being able to upgrade to itanium ... except itanium hadn't seen any update (late 90s had various of the 370/390 software emulators thinking itanium would offer significant emulation thruput). one of your articles: http://www.isham-research.co.uk/platslns4.html there is possible more progress now going on with itanium-2. there is some comment about ibm being wary of pushing ibm's competitive unix offerings too hard with commercial customers because it might take market away from traditional mainframes. from 7/8/2002 ... HP touts advantages of Itanium 2 http://news.com.com/HP+touts+advantages+of+Itanium+2/2100-1001_3-942252.html ... current superdome page http://www.hp.com/products1/servers/scalableservers/superdome/index.html various benchmarks http://www.hp.com/products1/servers/scalableservers/superdome/index.html 64-way pa-risc superdome specint (june 2002) http://www.spec.org/cpu2000/results/res2002q3/cpu2000-20020715-01481.html tpc-c http://www.tpc.org/tpcc/results/tpcc_perf_results.asp above lists superdome as 4th ... with ibm (non-mainframes) holding top three positions. and a few additional historical oriented posts involving mainframe, 801, risk, and itanium tie-ins (there used to be a joke that there were actually only 200 people in the business): http://www.garlic.com/~lynn/2006.html#39 What happens if CR's are directly changed? http://www.garlic.com/~lynn/2006e.html#1 About TLB in lower-level caches http://www.garlic.com/~lynn/2006p.html#42 old hypervisor email ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
