Types of logical partition configurations

This topic provides an overview of the types of logical partition configurations including the manufacturing default configuration, the service partition, the Virtual I/O Server partition, and i5/OS^® partitions on IBM^® eServer™ p5 servers.

• Manufacturing default configuration
  The manufacturing default configuration is the initial partition setup of the managed system as received from your service provider.
• Service partition
  If you are using the Hardware Management Console (HMC) to manage systems and the HMC becomes unavailable, then you can use the service partition to perform service-related tasks on systems.
• Virtual I/O Server partition
  The Virtual I/O Server provides virtual SCSI and shared Ethernet capability to client logical partitions on IBM eServer p5, IBM System p5™, and IBM eServer OpenPower™ systems.
• i5/OS on IBM System p5 and eServer p5 servers
  This topic provides information about some limitations and constraints that exist for i5/OS on an IBM System p5 and eServer p5.
