; ;PowerVM概念;IBM 是虚拟化的领导者;什么是 PowerVM? ;PowerVM关键技术;Networks and network storage;微分区技术;LPARs are defined to be dedicated or shared Dedicated partitions use whole number of CPUs Shared partitions use whole or fractions of CPUs Shared processor pools - subset of physical CPUs in a system Entitled capacity expressed in the form of number of 1% CPU units (easy to do, even the HMC passwd is simple to guess abc123, first time was linked to US)*** Desired: Size of partition at boot time Minimum: Partition won’t start if Minimum capacity not available Maximum: DLPAR cannot exceed this capacity Divided among the virtual processors within a shared processor pool Uncapped capacity cannot exceed number of virtual processors Capped vs uncapped Capped: 不允许超过其分配的CPU容量 Uncapped: 允许超过其分配的CPU容量;Example;受限(Capped)和不受限(Uncapped)分区;Shared processor pool;虚拟I/O服务器(VIOS);虚拟以太网;Ethernet Switch;;虚拟 SCSI;Dedicated Adapter Environment;IVE卡 端口示意图;Port Group及logical port;Integrated Virtualization Manager;动态分区迁移(Live Partition Mobility);动态分区迁移;AIX Workload Partitions（WPar）;Workload Partition QA; ;PowerVM高级特性;NPIV (N_Port ID Virtualization);NPIV;NPIV ;Active Memory Sharing;Active Memory Sharing;Additional Information
