oh ... and in the early 90s ... when we were doing ha/cmp product and talking to some number of trading operations (including SIAC which ran datacenter operations for NYSE) ... with respect to what would the impact of an outage be. One computer in tall skyscraper in LA supposedly earn more money in 24hr period than the aggregate annual salary of everybody that worked in the bldg ... plus the annual lease on the bldg. there was another instance when a trading operation had an environmental outage and the NYSE traffic volume was down 1/3rd that day.
misc. past posts mentioning ha/cmp http://www.garlic.com/~lynn/subtopic.html#hacmp I had coined the terms "geographic survivability" and "disaster survivability" (to differentiate from disaster/recovery) when I was out marketing ha/cmp. I had also been asked to write a section for the "corporate continuous availability strategy" document ... however the section got pulled after complaints from both Rochester and POK (basically at the time, they weren't able to meet the requirements). misc. past posts mentioning availability http://www.garlic.com/~lynn/submain.html#available semi-related ... misc. past posts mentioning assurance http://www.garlic.com/~lynn/subintegrity.html#assurance for a little other mainframe "available" topic drift ... long ago and far away ... my wife had been con'ed into going to POK to be in charge of loosely-coupled architecture ... while there she did peer-coupled shared data architecture ... misc. past posts http://www.garlic.com/~lynn/submain.html#shareddata which, except for IMS hot-standby, saw very little uptake until sysplex. Both because of the little uptake (focus on tightly-coupled multiprocessing at the time) and constant battles with communication group (insisting loosely-coupled operation needed to use SNA ... there were temporary truces where she could use anything she wanted within walls of the datacenters ... but SNA had to be used for everything that crossed walls of the datacenter) ... she didn't remain long in the position. -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- 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
