That use of orthogonal is common in computer science. Axes at right ang
les (orthogonal) are 
used to represent independent variables. These variables can be manipulat
ed independently. So in 
this sense orthogonal and independent are similar. But in computer sc
ience they talk about 
orthogonal design, rather then independent design, because the latter
 could mean many other 
things. 

I'm with Alan, and not just because he spells his name right!

Sir Alan probably had the thumb at the wrong spot in the dictionary.
Maybe he meant independent or not defined by instead. Working with
mini disks we have learned not to expect the model number to define
the number of cylinders, and we probably rarely have to.

IMHO it's an omission that the number of cylinders of the disk is not
in the monitor data.

No, finite fields cannot be ordered. In any ordered field 1  2  3  4

 How then do I have actual volumes on my system of 32,760 cyls.
 That's not divisible by 1113 (ds8000 here).

Marcy: Sorry, I was not clear. Allocation is in multiples of 1113
cylinders. You can make a volume whatever size you want, but if
it is not a multiple of 1113 cylinders, the remainder up to the
next 1113 cylinder boundary is not usable. Therefore, if you
defined a volume of 100 cylinders, you would be wasting 1013
cylinders.

Back in the Good Old Days with RTM, I had a modification that would
identify the different 3390 models on the device screen, with '3393' for
a model 3, '3399' for a model 9, '339M' for a model 27, and '339X' for
everything else (which at the time the three models were all we
had.)  With PTK we can't do that, unfortunately, and with all the
changes they've put into CP, it would take a big-time rewrite of RTM to
make it work past zVM 5.1.0. 
 
I agree with Marcy in that it would be very nice to be able to have some
way of knowing which model 3390 you are looking at.  Even being able to
have a customized screen that would read a table of addresses and
matching in the correct device type would be useful.

(5b+4) / (2b+7) = 3
5b+4 = 3(2b+7)

b=-17

To double check, we substitute b=-17 into:

IT'S SILLY.  MVS demands CKD,  but then hardly uses it.
So the other mainframe op systems are saddled with track-and-record,
prevented from doing just data like the rest of the civilized world.

MVS requires CKD for a few piddly things
but in the heavy lifting it uses VSAM which squishes out the
track and record geometry in favor of demand pagable storage.
If they too are going to make disk look like RAM, then why not
use disk geometry that natually matches RAM?

How many cylinders in a mod 9?
Is there such thing as a mod 27 (32,760 cyl) and mod 54 (65520)?  Or are
these just mod 9s of a different size? My storage folks don't believe me
(I'm reading $DASD$ CONSTS S) that they are all just variable sized mod
9.

Re: DASD cylinders

2007-03-06 Thread RPN01
There may not be a physical 3390 Mod 27. As newer DASD hardware has been
created, and with the need for larger and larger disks, the new hardware
emulates the 3390 in larger and larger sizes. We regularly use 3390 mod 27
DASD, with 32,760 cylinders on each device. These are emulated on portions
of disks with 9 inch platters. We¹re talking about going to 3390 mod 54, and
I¹ve seen messages talking about 3390 mod 81.

These are not ³just variable sized 3390 mod 9¹s². And your storage folks are
correct, none of these devices ever really existed. But then, how many shops
have any actual 3390 devices left at all? Ours have been emulated for many
years. EMC, Hitachi, IBM Shark, IBM DS8000... They all ³do² 3390, in varying
sizes and with newer features than a 3390 ever thought of. (Snapshot copy,
mirroring, ...)

I see that the $DASD$ CONSTS S file shows a 3390-9 as having 65,520
cylinders, but such a beast never lived that I know of. We¹ve just been
honoring the 3390 all these years by trying to do things they would have
done them. Had FBA been more popular at the time of the real 3390¹s, we
might be seeing 3350 mod 81¹s instead.

Not really.   3339 * 3 = 10017.   10017 * 3 = 30051  and 30051  32760.
