This extension is dedicated to vSphere, VMare's server virtualization platform which automates the management of virtual machines. It enhances iTop's CMDB by modelizing vSphere elements that are not part of iTop's default virtualization CIs (Virtual Machines, Hypervisors, Farms) and by adding attributes to some of these existing virtualization devices. Together with the Data collector for vSphere, it enables vSphere administrators to fetch in iTop the key elements of their vSphere infrastructure.
Features
When installed on iTop, the extension creates or enhances a set of classes dedicated to or related to the vSphere environment:
-

Usage
Datastore
A datastore is a logical
container that hides specifics of physical storage from virtual
machines and provides a uniform model for storing the virtual
machine files.

Creating a new Datastore
Type the Class name in the Quick create area to
create a new object, then fill the form and press the
Create button.
Farm
A Farm
(or cluster) is a group of Hypervisors pooled together and sharing
storage resources to provide an overall fault tolerant system for
hosting Virtual Machines.
Farm Tabs
The extensions adds one n:n relation to the datamodel.
| Tab | Description |
|---|---|
| Remote Datastores | Datastores located remotely across the network |
Hypervisor
A hypervisor is a
virtualization software (ESX in the vSphere world), running on a
physical Server and supporting the creation of Virtual
Machines.
Hypervisor Properties
The extension adds two attributes to the datamodel…
| Name | Type | Description | Mandatory? |
|---|---|---|---|
| UUID | Alphanumeric string | Universal Unique IDentifier | No |
| Host ID | Alphanumeric string | vSphere Host IDentifier | No |
Tabs
.. and two n:n relations.
| Tab | Description |
|---|---|
| Local Datastores | Datastores located on the server hosting the hypervisor |
| Remote Datastores | Datastores located remotely across the network |
Virtual Machine
A Virtual
Machine is the virtual equivalent to a Server. It is hosted
either on an Hypervisor or on a Farm.
Virtual Machine Properties
The extension adds one attribute to the datamodel…
| Name | Type | Description | Mandatory? |
|---|---|---|---|
| UUID* | Alphanumeric string | Universal Unique IDentifier | No |
| Power state | Possible values: On, Off, Suspended | - | No |
Tabs
.. and a n:n relation.
| Tab | Description |
|---|---|
| Datastores | Datastores used by the virtual machine |
Storage system
A Storage
System is used in iTop to describe any storage system that can
be attached to either a SAN or an Ethernet network. The logical
unit of storage managed by a Storage System is a Logical
Volume.
Tabs
The extension only adds a n:n relation to the datamodel.
| Tab | Description |
|---|---|
| Datastores | Datastores using the storage system as network storage |
Server
A Server is typically used in
iTop to document a physical server machine.
Server Properties
The extension only adds one attribute to the datamodel.
| Name | Type | Description | Mandatory? |
|---|---|---|---|
| Host ID | Alphanumeric string | vSphere Host IDentifier | No |
