Use this topic to help gain an understanding of what to consider
when planning for the Virtual I/O Server.
In this section, you will find information about planning for the Virtual I/O Server.
Planning for Virtual I/O Server using system plans
You can use the System Planning Tool (SPT)
to create a system plan that includes configuration specifications for the Virtual I/O Server. You can also use the Hardware Management Console (HMC) or the Integrated Virtualization Manager to
create a system plan based on an existing system configuration.
Specifications
This topic defines the range of configuration possibilities, including
the minimum number of resources needed and the maximum number or resources
allowed.
Capacity planning
This topic includes capacity-planning considerations for the Virtual I/O Server, including information
about hardware resources and limitations.
Redundancy considerations
Redundancy options are available at several levels in the virtual
I/O environment. Multipathing and RAID redundancy options exist for both the Virtual I/O Server and client partitions.
Ethernet Link Aggregation (also called EtherChannel) is also an option for the client
partitions, and the Virtual I/O Server provides Shared Ethernet Adapter failover. There is
also support for node failover (HACMP™) for nodes using virtual I/O resources.
Security considerations
Review the security considerations for Virtual SCSI,
virtual Ethernet, and Shared Ethernet Adapter and
the additional security options available.
