HP Matrix Operating Environment 7.3 and 7.3 Update 1 Logical Server Management User Guide

2 Managing fluid cross-technology logical servers
Heterogeneous server environments (multiple vendors, server types, product generations, and
product families) exist in most datacenters. Cross-technology logical servers allow you to choose
server configurations that make sense for your environment without having to consider the mechanics
of moving images and the underlying technologies.
Restrictions on using cross-technology logical servers
Cross-technology logical servers can be moved between ProLiant server blades with Virtual Connect
to ESX and back, between Integrity server blades with Virtual Connect and Integrity VM and back,
and between servers with Virtual Connect with unlike configurations.
Such capabilities can be useful for a variety of scenarios, including moving physical to virtual
within a site or disaster recovery scenarios, which may involve physical servers at one site and
virtual machines at another site. For additional information (including preparing the OS for such
movement), see the HP Matrix Operating Environment Recovery Management User Guide at
www.hp.com/go/matrixoe/docs.
Using the Matrix Operating Environment you can:
• Configure and manage a logical server that can perform physical to virtual cross-technology
movements within the datacenter.
• Configure and manage a DR Protected logical server that can be failed over across data
centers in a cross-technology movement.
The following are limitations for creating and managing cross-technology logical servers.
• Valid targets for activating or moving a cross-technology logical server:
ESX VM Hosts◦
◦ vPars and Integrity VM
◦ ProLiant c-Class servers with Virtual Connect
◦ HP Integrity servers with Virtual Connect
• Storage requirements:
SAN volume presented to an ESX VM Host (RDM disk) that can be added to a Virtual
Connect profile
◦
◦ Data store shared on a SAN or iSCSI volume (to store the virtual machine management
configuration file and RDM mapping file [.vmdk] on the ESX VM Host)
explicitly select the HP-UX Portable Image product
• Network requirements:
◦ Single or multiple networks (limited to 4 by ESX)
Not supported: VLAN networks
New and enhanced features that allow you to create and manage cross-technology logical servers
(sometimes known as portable, or p2v and v2p logical servers) are described in the following
sections.
Integrity VM and HP-UX cross-technology logical servers
Cross-technology logical server moves are supported on ESX VM Hosts and Integrity VM Hosts.
The following sections describe the behavior and requirements of logical servers on Integrity VM.
