    6. 6. LPAR Setup with HMC Non-Volatile RAM POWER5 Hypervisor Unassigned Resources LPAR Allocation Tables HMC Status Command/Response Virtual Consoles Service Processor Processors Mem Regions I/O Slots Server Ethernet Partition 2 Linux I5/OS Partition 1
    7. 7. Components of Power 5 Hardware <ul><li>CEC – Contains processors, memory, service processor </li></ul><ul><li>Power System/RIO Link – links to connect enclosures </li></ul><ul><li>Expansion Towers – DASD, Buses </li></ul><ul><li>Hypervisor – Firmware to virtualize all hardware for each partition </li></ul><ul><li>Operating Systems – i5/OS, AIX, Linux </li></ul><ul><li>HMC – Hardware Management Console </li></ul>
    8. 8. What is a Hypervisor? <ul><li>LOW level hardware virtualization software </li></ul><ul><li>Runs on CEC (main system) CPU and resides in CEC Memory </li></ul><ul><li>Loaded into the CEC by the FSP on base system IPL </li></ul><ul><li>Provides various RAS functions to partitions </li></ul><ul><li>Virtualizes all system hardware into multiple, independent, logical partitions (memory, CPUs, buses, etc) </li></ul><ul><li>Provides Virtual and/or Dedicated processor resources </li></ul><ul><li>The Virtual Service Processor (VSP) is part of the Hypervisor </li></ul><ul><li>Virtual TTY, Virtual Serial, Virtual Ethernet </li></ul>
    9. 9. What is a Service Processor? <ul><li>Service processors have been around for a long time. In older, non-partitionable hardware, the service processor was a separate, embedded computer that supported the main OS. On partitioned hardware, all partitions have a Virtual Service Processor (VSP), provided by the Hypervisor. VSP functions include: </li></ul><ul><ul><li>Manage OS debugging (Mainstore dumps, Virtual I/O) </li></ul></ul><ul><ul><li>Provides access to various system settings </li></ul></ul><ul><ul><li>Provide a virtual control panel for a partition </li></ul></ul><ul><ul><li>Provide various HMC interfaces for partition control </li></ul></ul>
    10. 10. Legacy iSeries LPAR vs Power 5 / 6 LPAR <ul><li>Power 5 / 6 LPAR </li></ul><ul><li>Primary Partition 이란 개념이 없음 </li></ul><ul><li>I5/OS , AIX and Linux Partitioning </li></ul><ul><li>HMC LPAR configuration </li></ul><ul><li>CPU : Power 5 , Power 6 </li></ul><ul><li>Legacy LPAR </li></ul><ul><li>P rimary partition 이 항상 Power on 되어 있어야 함 </li></ul><ul><li>Only support i5/os and Linux </li></ul><ul><li>Green screen LPAR configuration </li></ul><ul><li>CPU : Power 4 (and previous) </li></ul>
