mss/3850 provided simulated 3330s (icebergs) staged from tape cartridges. originally had real 3330 drives for staging the simulated 3330 drives. mss/3850 had two modes ... staging a full cartridge or staging six 3330 cylinders (at a time). i/o done to a simulated 3330 address could get back a unit check with "cylinder fault" in the sense data ... prompting for the operating system to stage the appropriate data from tape to disk. later there was a mss/3850 option that would use 3350 drives for staging the simulated 3330 data. later during the ADSTAR period in san jose ... there was the C-STAR project which was working on a new disk controller that was to suppose to provide equivalent function to the STK (iceberg/9200, different project, different vendor, same name) controller that had virtualized disks (compression and various other functions) ... as well as raid support. Slightly later, IBM licensed and marketed the STK iceberg/9200 controller. the stk iceberg was some 25 years after the 3330 iceberg. some 3850/mss pictures http://www.columbia.edu/acis/history/mss.html http://www-03.ibm.com/ibm/history/exhibits/storage/storage_3850.html a references from search engine mentioning stk iceberg/9200 http://www.findarticles.com/p/articles/mi_m0EIN/is_1995_Feb_7/ai_16420403 http://calbears.findarticles.com/p/articles/mi_m0EIN/is_1995_April_18/ai_16828928 http://storageadvisors.adaptec.com/2005/12/02/the-origin-of-raid-6/ ---------------------------------------------------------------------- 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
