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.
For additional information, see the HP Matrix Operating Environment 7.0 Recovery Management
User Guide.
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◦
◦ HP Integrity VM Hosts (racks and server blades)
◦ 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 Insight Control virtual machine
management configuration file and RDM mapping file [.vmdk] on the ESX VM Host)
Not supported: SPM (catalog) storage volumes
In this release, catalog storage pool entries are supported on servers with Virtual Connect
logical servers only. Catalog storage pool entries cannot be used with cross-technology
logical servers that may be activated on an ESX or Integrity VM Host.
• 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.
Table 5 provides a summary of the Integrity VM and HP-UX cross-technology logical server features
added to logical server management.
