3.1.2 Hardware resources managed The <strong>Advanced</strong> <strong>POWER</strong> <strong>Virtualization</strong> feature that enables Micro-Partitioning on a server provides the Virtual I/O Server installation media. A logical partition with enough resources to share to other partitions is also required. The following minimum hardware requirements must be available to create the Virtual I/O Server: <strong>POWER</strong>5 server The Virtual I/O capable machine. Hardware Management Console The HMC is needed to create the partition and assign resources or an installed IVM either on the predefined partition or pre-installed. Storage adapter The server partition needs at least one storage adapter. Physical disk Ethernet adapter Memory If you want to share your disk to client partitions, you need a disk large enough to make sufficient-sized logical volumes on it. This adapter is needed if you want to allow securely routed network traffic from a virtual Ethernet to a real network adapter. At least 512 MB of memory is needed. Similar to an operating system, the complexity of the I/O subsystem and the number of the virtual devices have a bearing on the amount of memory required, such as when using multiple paths to SAN storage devices. Virtual I/O Server Version 1.3 is designed for selected configurations that include specific models of IBM and other vendor storage products. Consult your IBM representative or Business Partner for the latest information and included configurations. Virtual devices exported to client partitions by the Virtual I/O Server must be attached through one of the following physical adapters: ► PCI 4-Channel Ultra3 SCSI RAID Adapter (FC 2498) ► PCI-X Dual Channel Ultra320 SCSI RAID Adapter (FC 5703) ► Dual Channel SCSI RAID Enablement Card (FC 5709) ► PCI-X Dual Channel Ultra320 SCSI Adapter (FC 5712) ► 2 Gigabit Fibre Channel PCI-X Adapter (FC 5716) ► 2 Gigabit Fibre Channel Adapter for 64-bit PCI Bus (FC 6228) ► 2 Gigabit Fibre Channel PCI-X Adapter (FC 6239) 122 <strong>Advanced</strong> <strong>POWER</strong> <strong>Virtualization</strong> on IBM System p5
Careful planning is recommended before you begin the configuration and installation of your Virtual I/O Server and client partitions. Depending on the type of workload and needs of an application, consider mixing virtual and physical devices. For example, if your application benefits from fast disk access, then plan a physical adapter dedicated to this partition. 3.1.3 Software packaging and support Installation of the Virtual I/O Server partition is performed from a special mksysb DVD-ROM that is provided to clients that order the <strong>Advanced</strong> <strong>POWER</strong> <strong>Virtualization</strong> feature, at an additional charge. For the p5-590 and p5-595, this feature is already included. The Virtual I/O Server software is only supported in Virtual I/O Server partitions. The Virtual I/O Server Version 1.3 DVD-ROM installation media can be installed in the following ways: ► ► ► Media (assigning the DVD-ROM drive to the partition and booting from the media). The HMC (inserting the media in the DVD-ROM drive on the HMC and using the installios command). Using the DVD-ROM media together with the NIM server and executing the smitty installios command (the secure shell needs to be working between NIM and HMC). Important: ► For IVM, there is no need to assign the DVD-ROM for the partition because VIOS installs on a predefined partition. ► The installios command is not applicable for IVM managed systems. For more information about the installation of the Virtual I/O Server, refer to 3.3, “Virtual I/O Server software installation” on page 142. Chapter 3.
