Could you please explain this statement : "GDPS does not require z/OS to run at either primary, secondary or tertiary locations" ? It might be just a confusion on terminology but I thought GDPS always involved z/OS ?

Whether intentional or not, methinks you may have insulted the intelligence of your readership (again).<div>&nbsp;</div> Those seeking a more factual perspective of GDDR vs. GDPS and EMC vs. IBM stock performance might want to follow the link to my blog below...

All corporations try to be profitable, I do not think anyone doubts that. TonyP, the stock chart graph is really an all time low. You are of course biased but do you seriously believe that anyone would buy your argument about the shareholders interpretations? Basic math tells you that the graph will look very different depending on the chosen time span. I believe you should avoid these kind of statements if you want to be taken seriously by customers.

Marc,My apologies. I was thinking one thing but wrote another. GDPS was originally for z/OS data only, but has been extended to support other data, including Linux data. That did not come across as I wrote above, so I will update to say:<div>&nbsp;</div> "GDPS supports a mix of OS data. z/OS and Linux data can all be managed by GDPS."-- Tony

AO,Fair enough. I was trying to point out that both IBM and EMC are (at this time anyways) for-profit companies, and both corporations profit from the recent resurgence in interest in mainframe technologies. I chose six months because that was when IBM started sharing its views on the new z10 EC mainframe, but provided an active link to Yahoo Finance so that people could generate their own comparisons. -- Tony
