Re: real vs. emulated CKD

If you had 3990-6 control units, you could do the equivalent of RAID1 called 
dual-copy on real 3390s.  I remember swapping HDA's on several occasions 
concurrently using that capability.

real vs. emulated CKD

I know it has been decades since IBM manufactured its last real CKD

Just curious.

 I still remember the early 80's, on a 3031/3033 or so I think, when 
 IBM decided to sell memory in 1MB units only. We needed 0.5 MB 
 expansion for the next year and my manager was very angry with IBM 
 about the unnecessary waste of money because of this new policy. So 1 
 MB was a substantial investment at that time. 

303x (along with 3081) was qd projects kicked off after FS imploded. 
http://www.garlic.com/~lynn/submain.html#futuresys 

3031 was 158 engine with just 370 microcode and the integrated channel 
microcode moved to a 2nd 158 engine called channel director; 3032 was 
168-3 with new covers and configured to work with external channel 
director, 3033 was 168-3 logic remapped to chips that were 20% faster 
(also had more circuits per chip, some late logic rework to increase use 
of onchip logic, increased 3033 to 1.5times 168-3). 

MVS in 3033 timeframe was increasingly enormous bloat ... but the amount 
of system real storage approaching 16mbyte and amount of virtual address 
space approaching 16mbyte (even with each application getting its own 
16mbyte virtual address space, MVS requirement was approaching 16mbyte). 

to address the real storage bloat, a hack was done to have 16mbyte real 
storage even tho 370 didn't support 16mbyte real storage addressing. 
IDALs introduced with 370 was 32bit field for i/o transfer addresses, it 
was leveraged for doing i/o to real addresses 16mbyte. The 370 page 
table entry was 16bits, 12bit page number, 2 defined bits, and 2 
undefined bits. The 2 undefined bits were co-opted to prefix the page 
number forming 14bit page number (allowing to generate up to 64mbyte 
addressing). While instruction addressing was still 24bit/16mbyte, 
virtual addresses could be translated into 26bit/64mbyte real addresses. 

OS/360 heritage has enormously ingrained pointer passing API 
paradigm. With everything in single same address (OS/360 real storage 
and VS2/SVS) that wasn't a problem. Moving to VS2/MVS with different 
16mbyte virtual address space for each application represented enormous 
problem/opportunity. It started out with image of the MVS kernel taking 
up half of each 16mbyte application virtual address space (8mbyte, with 
application and kernel in same virtual address space can use pointer 
passing API for kernel calls to access application parameters). 

That left the problem of various MVS subsystems that moved into their 
own separate virtual address space. To address applications calling 
subsystem, the common segment area (1mbyte CSA) was defined in each 
virtual address space for parameters used in subsystem calls (leaving 
7mbytes for applications). However as systems size grew (with 3033), CSA 
size had to grow (proportional to both number subsystems and 
concurrently executing applications) ...  becoming common system area 
(multiple one mbyte segments). Later in 3033 time-frame, CSA was 
5-6mbytes at many customers (leaving 2-3mbytes address space for 
applications), threatening to become 8mbytes (leaving nothing for 
applications). 

all the problems contributed to the attack of the vm/4341s ... a cluster 
of vm/4341s had more aggregate processing than 3033 at lower cost, lower 
environmental and floor space. Also 4341 channels were faster  more 
efficient than the 303x channel director (158 engine running integrated 
channel microcode).  I've mentioned before that the head of POK trying 
to fight off the Endicott 4341s, got the corporate allocation of a 
critical 4341 manufacturing component cut in half. Places like LLNL were 
doing benchmarks looking for 70 4341s for datacenter compute farm 
... the leading edge of cluster supercomputers. Large corporations were 
also ordering hundreds of 4341s at a time, placing them out in 
departmental areas ... the leading edge of the distributed computing 
tsunami. some old email 
http://www.garlic.com/~lynn/lhwemail.html#4341 

MVS was locked out of the exploding distributed computing market.  The 
3380 was high-end CKD DASD ... however the only mid-range disks were FBA 
(3310  3370) appropriate for placing out in departmental areas 
(non-datacenter environment, converted departmental supply  conference 
rooms). Eventually they did come out with 3375 (CKD simulated on 3370) 
to try and provide MVS an entry into this market. However, MVS system 
tended to require 10-30 people for carefeeding ... which scaled poorly 
to hundreds of distributed departmental computers (IPL and run with 
little or no human intervention).

did not have direct support for FBA in its customer-usable access method

Re: real vs. emulated CKD

2014-06-02 Thread Pommier, Rex
Bill,

While I don't know when the 3390s last rolled off the assembly line, I believe 
they were all SLEDs.  After that came the short-lived 9340/9345 subsystem which 
had a different track length than the 3390 (built on 5 1/4 inch drives), then 
the RAMAC II devices which might be what you're thinking of.  These things 
emulated the 3990/3390 SLEDs on (I believe) 3 1/2 inch SCSI drives, packed 4 in 
a drawer in either a RAID1 or RAID5 configuration.  

I don't know how they compared to the 3390s performance-wise, but we replaced a 
bunch of 3380-Es with a combination of the 9340s and RAMAC IIs and they ran 
circles around the 3380s, not to mention taking up a LOT less floor space!  :-)

this ibm-main post (from last summer) says last ckd (3390) rolled off
1993 (towards the bottom, I even weight in)
https://groups.google.com/forum/#!topic/bit.listserv.ibm-main/zAUn9kAkykU
which would go along with this
http://www-03.ibm.com/ibm/history/exhibits/storage/storage_3390.html

note however, 3380  3390 were increasingly becoming fixed cell in
large part because of the error correcting technology ... while still
striving to simulate ckd ... before switching over to using straight
industry standard fixed-block disks ... with higher level ckd simulation
(i.e. 3375/3370)

Re: real vs. emulated CKD

I will rephrase my question.  When did any vendor last ship a 3390 DASD to 
anyone with non-RAID SLEDs inside for use on any kind of operating system which 
did not have direct support for FBA in its customer-usable access method 
repertoire?  There must have been some kind of announcement made which is still 
findable online.  IBM continued to manufacture and sell things after this date 
that they called 3390s but which were implemented internally with RAID, I 
believe.

As far as I understand, you simply ask about last date of SLED 
(non-RAID) disk delivery. Well, it's hard to find it. You can find End 
Of Marketing date for every vendor (and OEM), but it need not to be real 
date of last delivery. I saw soem deliveries done way after EOM.


BTW: AFAIK for IBM first non-SLED DASD subsystem would be RAMAC II, but 
previous DASD wasn't 3390, it was 9340 or so.

BTW: I worked with RAMAC II. I didn't like it (to avoid curses).
