Note that this is a statement of direction. A not as yet announced release of z/VM will be a pre-req for this support. Damn good question as to licensing! With our current licensing rules you would have to license z/VM on ALL the processors on the z10 if you are using this mode of LPAR (CPs and IFLs). This would probably also apply to any software running on z/VM that could run on either processor type (like VTAM). We will have to wait for the announcement to see what the licsening folks come up with, but I will certainly discuss this with them in advance. > And then on the Linux side, would you then get charged for the > 390 engines? i.e. DB2/UDB and Oracle Most of IBM's products which run on Linux on z (such as DB2 and WebSphere) have "sub-capacity" pricing which could be used in this environment. I believe Oracle and some (many?) of the ISVs also do this. You would need to talk to your ISV. Jim
