Hi,

How widely De-Duplication adopted in Mainframes? I know it is very popular in Open systems.

Thanks
Ramya

you can learn about Mainframes and the strategies at z/OS Basics

probably why it is such a big thing on open systems, is that it is such a problem.

Thanks. But I wanted to know the current industry trend in adopting de-dupe. And If any one would suggest the same to a client as one of the ways for mainframe storage optimization?

but I doubt if anyone here wants to educate you so that you can BS your clients.

people like you give the consultant industry a bad name.
you have no business giving advice about something that you obviously know nothing about.

And why is that Dick?

As far as i see it, there is nothing new about that. Its done again and again. You can only laugh about people that buy a lot of BS, but then they
are probably asking for it. And dont forget its all about money (i think).

Add my vote to that. If someone can talk there way in to a job they are not qualified to do(as long as it is legal) , then good luck to them...... they will either sink or learn to swim very quickly

I agree with you both, Peter, Nevilh.

I probably decided to jump on him, just because.

I don't jump on nice people, or anyone who exhibits a scintilla of intelligence.

he did not have the sense to pick-up on that, and instead came back with a comment indicating that he had no idea that we have been de-duppin' before 'open systems' existed.

Hello,

Once upon a time some amount of effort was put into determining if some/all of the data already existed - and then using it. Preventing duplication, so de-duping was mostly not an issue. . .

These days many "things" are thrown together from the data definitions up thru the code. Then someone notices the "new" system contains much of what some other system(s) contain(s) - wasting considerable resources.

I was at a ZoS roadshow at IBM about a year ago and they went on about de-duplication as the next big thing. I think at this stage it is done by add on boxes plugged into the device channels. Seemed to relate mainly to TAPE but hints this could become an inbuilt ZoS Mainframe feature somewhere down the track. I didn't fully understand how it works to be honest, but sounds a bit like the old VSAM index concept of making index records 'disappear' and reappear magically.

I don't know about any of you, but the "Ads by Google" box at the top of the page has been showing an offer for a free whitepaper from BUS-TECH on Mainframe Deduplication.

A useful link for some background on this. Sounds quite nice actually.
