Brings back some good memories - I enjoy reading your post, I seem to have forgotten more about my life at Boeing than I remember, short time, 11 years in Philly but I do recall the 4341 trail connected to some new state of the art 3390 controllers running MVS 4.3 ? or 5 strictly for an electronic mock up system for the V-22, I had a great pleasure working with some AI engineers and Wind Tunnel engineers on some off the wall projects. I remember the data center running microwave sender/receiver from one building to another to support CATIA workstations, not an IBM approved method to extend a channel but back them there were less options. so many other projects I can't even remember any longer :(
BCS then morphed into Boeing Shared Services group. I have some fond memories of those time and the GREAT folks I worked with. thanks again for the trip back in time. sorry to stray from the topic folks Carmen ----- Original Message ----- From: "Anne & Lynn Wheeler" <[email protected]> To: [email protected] Sent: Tuesday, December 6, 2016 3:39:45 PM Subject: Re: Why Can't You Buy z Mainframe Services from Amazon Cloud Services?

Part of the issue was that (especially initially), offshift online access was very light so there was little useage ... but in order to encourage offshit useage, the systems had to be available 7x24. Because of light useage there would be little recovery charges ... so lots of things were done to minimize offshift expenses. This was in the days when mainframes were leased and charges were based on system meter that ran whenever the processor and/or any channel was busy ... also everything had to be idle for at least 400milliseonds before it the system meter would stop (triva: long after mainframes had switched from leases to sales, MVS still had a time ever that went off every 400ms, making sure system meter would never stop). In any case, came up with special channel programs for terminal I/O ... that would let the channel "go idle" ... but would immediately startup when there was any characters. Also lots of support for "dark room" ... not requiring offshift operators. For big cloud megadatacenters, the price of systems has so dramatically dropped that they have hundreds of thousands of "blades" (each blade with more processing power than max. configured mainframe) supported by staff of 80-120 people per megadatacenter. Also with the dramatic cut in system cost, the major expense has increasingly become power & cooling. The big cloud datacenters have been on the leading edge of systems where power&cooling drop to near zero when idle ... but are effectively instant on for ondemand computing. while an undergraduate in the 60s, I was hired as fulltime boeing employee to help with the formation of boeing computer services ... consolidate all computing into independent business unit as part of better monetizing the investment (which would also have the freedom to sell computing services to non-boeing entities, a precursor to cloud computing). at the time, I thought renton data center was possibly the largest in the world with something like $200M-$300m (60s dollars) in ibm mainframe gear (for a period, there were 360/65s arriving faster than they could be installed, boxes were constantly being staged in the hallways outside the datacenter). there was disaster scenario where mt rainier warms up and the resulting mudslide takes out the renton datacenter. the analysis was that the cost of being w/o the renton datacenter for a week was more than the cost of the renton datacenter ... so there was a effort underway to repicate the renton datacenter up at the new 747 plant in everett. in any case, the politics with the different plant managers tended to dwarf any technical issues. -- 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: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
