All is it referring to the physical track size of the "real 3390-9?"
The 3390-9 spun at 1/3 the speed of the 3390-3, and each physical track presented 3 logical tracks to the channel program. Probably on of the earliest examples of virtualization for CKD. I think Amdahl and Hitachi virtualized the mod 9 differently to IBM, and the performance was a better because of that. Never got to test the PCM kit first hand, so I'm not 100% sure on that. Can you say RPS Miiiiiiiiiiissssssssssssssss? Ron -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of R.S.

OK, the manual is little bit out of date. ;-) It is SC26-7408-10, a book from z/OS 1.13 Collection. However IMHO nothing has changed in that area during last 10-20 years. I checked in z/OS 2.2 - it is fixed. -- Radoslaw Skorupka Lodz, Poland W dniu 2018-01-18 o 14:55, Steve Smith pisze: > I don't know what you mean by "current one", as I have V2R3 manual > (SC23-6852-30), and it has no such inconsistency in Appendix E, Table > 71, on page 428. > > sas > > 2018-01-17 19:08 GMT-05:00 R.S. <[email protected]>: >> I just read some chapter of DFSMS Macro Instructions for Datasets, the >> current one. >> And I found the manual claims a 3990-9 hac longer track size: it is 56669 - >> not 56664. >> Is it a typo or there is something I don't know??? >> (it is Appendix 1.5.4) >> > ---------------------------------------------------------------------- > For IBM-MAIN subscribe / signoff / archive access instructions, > send email to [email protected] with the message: INFO IBM-MAIN > . > ====================================================================== -- Treść tej wiadomości może zawierać informacje prawnie chronione Banku przeznaczone wyłącznie do użytku służbowego adresata.
