big part of the issue was alternative implementations for multi-track search used in vtocs and pds directories. misc. multi-track search stories http://www.garlic.com/~lynn/subtopic.html#dasd i was told that even when i provided them fully integrated and tested fba-support for mvs ... it would still cost $26m to ship the code (documentation training, ????, etc). part of the issue was that at the time, they thot they were selling disk as fast as they could. it was difficult to demonstrate incremental revenue for fba-support ... since it appeared to just move ckd revenue to fba revenue. the other arguments used at the time have only become more apparent with the passing of years. fba support was relatively simple for vm/cms ... since all of vm's kernel disk access & paging stuff ... and all the cms filesystem stuff ... had essentially been logical fba since their origin in the mid-60s. misc. past postings about the $26m http://www.garlic.com/~lynn/97.html#16 Why Mainframes? http://www.garlic.com/~lynn/97.html#29 IA64 Self Virtualizable? http://www.garlic.com/~lynn/99.html#75 Read if over 40 and have Mainframe background http://www.garlic.com/~lynn/2000.html#86 Ux's good points. http://www.garlic.com/~lynn/2000f.html#18 OT? http://www.garlic.com/~lynn/2000g.html#51 > 512 byte disk blocks (was: 4M pages are a bad idea) http://www.garlic.com/~lynn/2001.html#54 FBA History Question (was: RE: What's the meaning of track overfl ow?) http://www.garlic.com/~lynn/2001d.html#64 VTOC/VTOC INDEX/VVDS and performance (expansion of VTOC position) http://www.garlic.com/~lynn/2001g.html#32 Did AT&T offer Unix to Digital Equipment in the 70s? http://www.garlic.com/~lynn/2002.html#5 index searching http://www.garlic.com/~lynn/2002.html#10 index searching http://www.garlic.com/~lynn/2002g.html#13 Secure Device Drivers http://www.garlic.com/~lynn/2002l.html#47 Do any architectures use instruction count instead of timer http://www.garlic.com/~lynn/2003.html#15 vax6k.openecs.org rebirth http://www.garlic.com/~lynn/2003c.html#48 "average" DASD Blocksize http://www.garlic.com/~lynn/2003m.html#56 model 91/CRJE and IKJLEW http://www.garlic.com/~lynn/2004d.html#65 System/360 40 years old today http://www.garlic.com/~lynn/2004g.html#15 Infiniband - practicalities for small clusters http://www.garlic.com/~lynn/2004l.html#20 Is the solution FBA was Re: FW: Looking for Disk Calc http://www.garlic.com/~lynn/2004l.html#23 Is the solution FBA was Re: FW: Looking for Disk Calc http://www.garlic.com/~lynn/2004n.html#52 CKD Disks? http://www.garlic.com/~lynn/2005c.html#64 Is the solution FBA was Re: FW: Looking for Disk Calc http://www.garlic.com/~lynn/2005m.html#40 capacity of largest drive -- Anne & Lynn Wheeler | http://www.garlic.com/~lynn/ ---------------------------------------------------------------------- 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
