George, glad be of help. DataDirect is not a party in the IBM lawsuit, in fact, we are strongly in favor of IBM's specialty engine strategy. We have been able to achieve almost 100% zIIP eligibility in our Shadow products and deliver real TCO savings to our customers while remaining in strict compliance with IBM's zIIP offload rules. This could not have been done without IBM and their support. If your clients need further validation regarding the integrity of our approach, they may contact Mark Anzani, VP, Chief Technology Officer, System z.
Best, Gregg -----Original Message----- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of George Henke Sent: Monday, February 22, 2010 3:57 PM To: IBM-MAIN@bama.ua.edu Subject: Re: zAAp on zIIP Question Thank you very much, Gregg, for the enlightenment. My current client is seriously considering your product, SHADOW, after I informed them last week that a previous client was able to extend the life of their 2 GPP configuration enormously by installing your product, SHADOW. My previous client, who has been running your product now for some time, spoke very highly of it. I have read your posts and find them very helpful in removing any legal concerns to which my client is very sensitive. Does this mean that DataDirect has not been named as a party in the IBM suit?
