Right. The z architecture systems are only one of many possible Enterprise Level architectures. Many would argue that the i, p, and large Intel/AMD servers are also "Enterprise Level". But none of them implement z architecture. In fact, one could really argue that IBM totally dominates the i marketplace even more than the z. The i runs two possible OSes: i5/OS and Linux. i5/OS does not even have the ability to have "system level" vendors like CA because the majority of the OS is implemented in SLIC (System Licensed Internal Code) which would be like z/OS being implemented in millicode on the z. Once on an i, you are every bit as "locked in" to the i as z people say that they are "locked into" the z. And this is vendor nirvana. It is what MS wishes it could do, and tries to via software only. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
