The concept of books and channel subsystems are added to the architecture, and the maximum number of LPARs is increased. These architectural extensions provide the base for much larger zSeries machines. This IBM Redbooks publication provides an overview of these changes, and goes into more detail in selected areas. By removing memory, processor, and channel constraints, z990 can be used for major server consolidation activities. More granular options for nondisruptive maintenance, growth, and alterations provide better 7 x 24 x 365 operation. In general, no changes are needed for existing applications--allowing immediate growth into z990. Readers are assumed to have a general understanding of existing S/390 and zSeries hardware. Terms, acronyms, abbreviations, and concepts associated with existing systems are used without further introduction. 410 0$aIBM redbooks. 606 $aIBM computers 606 $aClient/server computing 615 0$aIBM computers. 615 0$aClient/server computing. 676 $a004 700 $aOgden$b Bill$01606611 701 $aFadel$b Luiz$01627551 701 $aFowler$b Roger$0165277 712 02$aInternational Business Machines Corporation.$bInternational Technical Support Organization. 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910824915903321 996 $aIBM eserver zSeries 990 technical introduction$94102783 997 $aUNINA
