Ted,
At The last place I worked they were mirroring 160+ volumes of work.
I did not design it but I sure as hell wouldn't have sent the data
line to NY via Denver (we were in Chicago).
The discrepancy I am (and have had others confirm it on here)
concerned about that there is some time before the copy is done, it
is done under the covers in the control unit. It may also involve
some cpu activity to accomplish this. Has this changed? I don't think
so, as people on here talk about it. Right now all I hear on here
(except from 1 or 2 people) is that it is "instant". I disagree, the
control unit may move some pointers around but there still has to be
some data movement and with the amounts of data that are being talked
about there is no way (short of breaking the rules of physics) that
this can be done *INSTANTLY*. Moving pointers around takes *SOME*
time (albeit small) data movement takes some time either small or
large (depending on amount). Now if you want to say the duplication
is fast, I will agree but instant? No sorry. We are not talking about
instant mash potatoes here. We are talking reality and in my universe
saying something is instant means less than 1 second.
As to my retirement you bring this up like you bring your ex up. Why
bother, get over them.

Well get it right
Ed, I have made this comment before!
Things have changed since you retired!
Some things you may have right.
But, in general, the world has moved on.
Array technology has improved.
Copy services have improved.
LE/COBOL has improved.
Either keep up with the technology, or sound like you're talking
out of the wrong orifice.
I found, with 5 months (involuntary) off, I missed some advances.
And, coming back to work at a shop that was less sophisticated than
the one I left, I missed a few more.
Keep up, or shut up.
Talking about the problems from 'my day' is just a trip down
Nastalgia Lane.
And, it is not a productive use of anybody's time!
And, the laser beam argument is way over the top!
