System z System p VMware Infrastructure Xen Sun Logical Domains (2006?) Microsoft Viridian ( ?) Hypervisor software runs on a host operating system. VMware GSX Microsoft Virtual Server HP Integrity VM Win4Lin User Mode Linux 4 Hardware partitioning subdivides a server into fractions, each of which can run an OS. Hypervisors use a thin layer of code to achieve fine-grained, dynamic resource sharing. Type 1 hypervisors with high efficiency and availability will become dominant for servers. Type 2 hypervisors will be mainly for clients where host OS integration is desirable.

17 PowerVM Live Mobility 17

18 PowerVM Live Mobility Move a running partition from one POWER6 server to another with no application downtime Movement to a different server with no loss of service Virtualized SAN SAN and and Network Infrastructure Reduce planned downtime by moving workloads to another server during system maintenance Rebalance processing power across servers when and where you need it Live Mobility requires the purchase of PowerVM Enterprise Edition 18

19 Mobility: Active and Inactive LPARs Active Mobility Active Migration is the actual movement of a running LPAR from one physical machine to another without disrupting the operation of the OS and applications running in that LPAR. Applicability Workload consolidation (e.g. many to one) Workload balancing (e.g. move to larger system) Planned CEC outages for maintenance/upgrades Impending CEC outages (e.g. hardware warning received) Inactive Mobility Inactive Migration transfers a partition that is logically powered off (not running) from one system to another.

Heterogeneous storage is pooled by the VIOS into a homogeneous pool of block storage Allocated to client LPARs in the form of generic SCSI LUNs. VIOS performs SCSI emulation and acts as the SCSI Target. F C F C SAN EMC 5000 IBM

31 New N-Port ID model N-Port ID Virtualization With NPIV VIOS's role is fundamentally different VIOS facilitates adapter sharing only No device level abstraction or emulation. Rather than a storage virtualizer, the VIOS serving NPIV is a passthru Provides a FCP connection from the client to the SAN.
