5 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.

Cross-technology logical servers can be moved between servers with Virtual Connect and ESX
virtual machines, and between servers with Virtual Connect with unlike configurations.

Following are the requirements and limitations for creating and managing cross-technology logical
servers.

Valid targets for activating or moving a cross-technology logical server:

ESX Hosts: 3.5, 3.5i, 4.0, 4.0i, 4.1, and 4.1i

ProLiant c-Class servers with Virtual Connect

Not supported: Servers with Virtual Connect with FCoE (Fibre Channel over Ethernet)
ports

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 VMM 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 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 logical servers) are described in the following sections.

Defining portability groups

Use the Modify

→Logical Server Portability Groups… screen to define a greater range of mobility

for logical servers. When you create a logical server and include it in a particular portability group,
you can potentially move the logical server to any target system within the portability group (as
long as you choose storage and a network that are visible across all targets) without regard to the
target’s underlying technology.

Logical server resource constraints, for example, CPU and memory requirements and network/SAN
connectivity, are evaluated solely within the context of the portability group with which the logical
server is associated.

There are two classes of portability groups: Default and User-defined.

Default portability groups:

Each Virtual Connect domain group

Each Operations Orchestration Workflow physical server

All ESX Virtual Machine Hosts
