System p5 Virtualization, Economic Benefits of
IT Simplification. International Technology
Group, 02/10/2006. Study methodology Companies
in financial services, manufacturing and retail
with 15 Billion revenues and total 200,000
employees focusing on UNIX large enterprise
environments with multiple, broad-ranging
applications. Study compared the cost of the
company's workload running on multiple vendor
servers and employing minimal virtualization to
the cost of the company's workload running on the
p5-510, 550, 570, 590 and 595 all using
Advanced POWER Virtualization APV. APV is
standard on System p5 590 and 595. Other System p
servers have the option to add APV except the
System p5 185. This cost analysis was performed
for financial services, manufacturing and retail
example environments with an overall average
savings of up to 62 in TCO savings by
virtualizing and consolidating on the System p
servers. For further information, see the white
paper at http//www-03.ibm.com/systems/p/library
/consult/ itg_p5virtualization.pdf Total Cost of
Ownership may not be reduced in each
consolidation case. TCO depends on the specific
customer environment, the existing environments
and staff, and the consolidation potential. , 5)

System p5 server was the key factor in our
decision, enabling us to run multiple independent
systems on the same physical machine. In our
opinion, IBM leads the market in this area. 1 -

Partition Mobility Active and Inactive LPARs

• Active Partition Mobility
• Active Partition 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 Partition Mobility
• Inactive Partition Migration transfers a
  partition that is logically powered off (not
  running) from one system to another.

Partition Mobility supported on POWER6 AIX 5.3,
AIX 6.1 and Linux
42
IBM System p Partition Mobility

• Move active Micro-Partitions between systems
• Reduce the impact of planned outages
• Relocate workloads to enable growth
• Provision new technology with no disruption to
  service

What Are Workload Partitions?
Separate regions of application space within a
single AIX image

• Partitioned system capacity
• Each Workload Partition obtains a regulated share
  of the processor and memory resources
• Each Workload Partition has separate network and
  filesystems and many system services (e.g.
  telnetd, etc.)
• Separate Administrative control
• Each partition is a separate
  
  administrative and security domain
• Shared system resources
• I/O Devices
• Processor
• Operating system
• Shared Library and Text

Consolidations Virtual Servers or Application
Regions?
Goal Consolidation Partition Mobility (Part of APV) Each Application Has Its Own AIX LPAR, Multiple LPARs Per Server Each Application Is In Its Own AIX WPAR, Multiple WPARs Per AIX
Fault Isolation Full isolation OS faults will only impact the specific LPAR Limited isolation OS faults will bring down all regions, but happen infrequently
Security Isolation Complete isolation between OSes shared nothing Only user space level isolation kernel level is still exposed
OS levels Different OS levels in LPARs possible Has to be the same across all WPARs
OS Service/Fix Level OS service fixes can be applied to individual LPAR OS images OS service fixes affect all WPARs, negatively impacting multi application - OS dependency
ISV Software Cost ISVs will count only the number of processorsin LPAR Many ISVs price based on number of CPUs, they will count all processors in OS image
Efficiency Good, but little sharing of OS resources leads to lower efficiency than with region approach Very good, due to extensive sharing of OS resources such as code or text
System Admin costs System admin costs dont go up linearly per OS image as cluster sys mgmt tools lower costs for managing multiple OS images TCO analysis based on number of OS images would favor regions, although in reality system administration costs will shift to per region level
Resource Granularity Fine grained Very fine grained
Mobility Active LPAR movement in 2007 Requires POWER6 Active WPAR movement in 2007 Requires AIX 5.4 (Can run on P4 and up)
Each approach comes with pros and cons, so the
choice depends on customer needs and preferences.
