The vSphere SDK for Perl is a client-side Perl framework that provides an easy-to-use scripting interface to the vSphere API.
Administrators and developers who are familiar with Perl can use the vSphere SDK for Perl to automate a wide variety of administrative, provisioning, and monitoring tasks in the vSphere environment.
The vSphere SDK for Perl includes ready-to-use utility applications, which you can immediately put to use in your virtual datacenter.
The vSphere SDK for Perl installation includes the WS-Management Perl Library, which allows you to write scripts that retrieve CIM data from the ESX host using CIMOM, a service that provides standard CIM management functions over a WBEM (Web-Based Enterprise Management).
You can use the SDK to manage ESX 3.0.x, ESX/ESXi 3.5, ESX/ESXi 4.0, ESX/ESXi 4.1, ESXi 5.0, vCenter Server 2.5, vCenter Server 4.0, vCenter Server 4.1, and vCenter Server 5.0.
