Network Asset Global Configuration Options
You can add devices to network asset management when devices are added to IMC. In addition, IMC
lets you configure how frequently automatic asset audit synchronization occurs. For more information
about this option, see " Configuring network asset audit options ."
Virtual Resource Management
VRM provides lets you manage virtual network devices such as physical servers, vManager (a server that
manages virtual servers), virtual machines, and virtual switches. You can view virtual network resource
configuration in Virtual Network View. By creating a vSwitch or port group, you can plan and manage
your network. VRM can manage four types of vManagers, Microsoft Virtual Machine Manager, VMware
vCenter Server, KVM, XenServer and CAS.
In addition, VRM provides the virtual machine migration function. A virtual machine can migrate from a
physical server with limited resources to a physical server with enough resources to ensure the efficiency
of the virtual machine. VRM automatically collects data on the vManager. In the Migration
Recommendation List, you can select manual or automatic migration. After the migration is complete,
you can view the migration report.
The vManager users must be granted proper privileges to exchange data between VRM and the
vManager, add, modify, and delete vSwitches and port groups, and perform virtual machine migration.
To read data from VMware vCenter Server, the user must have at least the read-only privilege. To add,
modify, or delete a vSwitch or port group, the user must be an administrator or have the network
configuration privilege on vCenter Server. To perform application or virtual machine migration, the user
must be an administrator or have the following privileges on vCenter Server:
• Resource > Querying VMotion
• Resource > Migration
• Resource > Migration recommendation
• Resource > Assigning virtual machines to resource pools
• Resource > Redirect
Only the root user can read data from an ESX server or perform other operations when the user directly
accesses the ESX server through VRM.
The domain users can perform all operations on Microsoft Virtual Machine Manager after they join the
local Users group of the VRM server. To enable VRM to read data from or perform other operations on
a Hyper-V server, make sure that the related user belongs to the Administrators group on the Hyper-V
server.
With the Topology function, you can see the virtual network architecture, facilitating planning a virtual
network.
Viewing virtual network
Virtual Network View displays all resources and their relationship in a virtual network in a list. The list can
expand and collapse, and includes three levels. In the list, the first-level nodes are physical servers (for
example, VMware ESX server or Microsoft Hyper-V server), the second-level nodes are virtual switches
created on the servers, and the third-level nodes are virtual machines connected to the virtual switches.
