zD&T (previously RD&T) is basically just zPDT under the covers with a few more additions. zPDT is primarily for ISVs whereas zD&T is more for your corporate world but no production work, just development and testing and even that is subject to some quite strict specifications. zD&T comes in basically 2 versions, the Personal Edition where each user has their own zD&T and license or via software licensing (which has confused the hell out of me, like all IBM software licensing). You can run it on a standalone x86 server, in a virtualized environment (which makes it easy to clone images, ala DevOps) and in a managed services such as a cloud based system.
It runs all the z operating systems that we all love (not older ones though) although z/VM is required for Sysplex operation and has some restrictions. There are various options on the amount of processors (zPDT is restricted here) and it does support IFLs and ZiiPs, in fact in the latest version of zPDT, the ZiiPs are 'free'. There is a wealth of information out there although trying to find the wheat from the chaff can be time consuming, the best starting point is the zPDT Redbook: http://www.redbooks.ibm.com/abstracts/sg248205.html?Open Sebastian ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
