Planning for the Virtual I/O Server
Use this topic to help gain an understanding of what to consider when planning for the Virtual I/O Server.
- Planning for Virtual I/O Server and client logical partitions by using system plans
You can use the System Planning Tool (SPT) to create a system plan that includes some basic configuration specifications for a Virtual I/O Server and client logical partitions. You can also use the Hardware Management Console (HMC) to create a system plan based on an existing system configuration. - Specifications required to create the Virtual I/O Server
This topic defines the range of configuration possibilities, including the minimum number of resources needed and the maximum number of resources allowed to create the Virtual I/O Server (VIOS). - Limitations and restrictions of the Virtual I/O Server configuration
Learn about Virtual I/O Server (VIOS) configuration limitations. - Capacity planning
This topic includes capacity-planning considerations for the Virtual I/O Server, including information about hardware resources and limitations. - Configuration requirements for shared memory
Review the requirements for the system, Virtual I/O Server (VIOS), logical partitions, and paging space devices so that you can successfully configure shared memory. - Redundancy considerations
Redundancy options are available at several levels in the virtual I/O environment. Multipathing, mirroring, and RAID redundancy options exist for the Virtual I/O Server and some client logical partitions. Ethernet Link Aggregation (also called EtherChannel) is also an option for the client logical partitions, and the Virtual I/O Server provides Shared Ethernet Adapter failover. There is also support for node failover (PowerHA® SystemMirror®) for nodes using virtual I/O resources. - Security considerations
Review the security considerations for virtual Small Computer Serial Interface (SCSI), virtual Ethernet, and Shared Ethernet Adapter and the additional security options available. - Limitations and restrictions for IBM i client logical partitions
With Virtual I/O Server, you can install IBM® i in a client logical partition on a POWER7® system. IBM i client logical partitions have unique system and storage requirements and considerations.
