Resource usage of Virtualization Jobs
This topic describes BMC Server Automation virtualization jobs and their resource usage:
Virtual Guest Job
A Virtual Guest Job constructs a virtual guest, with or without an OS, from a known vCenter Server or other virtual infrastructure. Configuration decisions for the new virtual guest are captured in a Virtual Guest Package.
Internally, Virtual Guest Jobs operate as BLPackage Deploy Jobs, so the behavior and resource demands of a Virtual Guest Job correspond to those of the Deploy Job. Virtual Guest Jobs require minimal Application Server resources.
For some steps in its operation, a Virtual Guest Job communicates with the vCenter Server through a custom object (CO) that must be installed on the vCenter Server.
The table shows a summary of resource usage by Virtual Guest Jobs.
Virtual Guest Jobs make demands on the vCenter Server to accomplish construction of the virtual guest.
Virtual Infrastructure Discovery Job
Also called a sprawl job, a Virtual Infrastructure Discovery Job scans the network to identify ESX servers or other virtual hosting environments and then interrogates them to identify guests that are hosted by that computer.
The following table shows a summary of resource usage by Virtual Infrastructure Discovery Jobs.
UCS Provision Jobs
A Cisco Unified Computing System (UCS) chassis consists of a number of hardware blades which act as a pool of computing resources. The chassis also includes a hardware entity (the Fabric Interconnect) that manages all the computing, network, and storage connectivity resources. The BMC Server Automation UCS CO communicates with this hardware entity.
A UCS template is a configuration that contains settings to configure a blade to become a server. This template contains server identity information (MAC address), networking configuration, and storage configurations (WWNN and WWPN). The UCS Provision Job takes a predefined template, applies the template to a stateless blade (so that the blade becomes a server with an identity), and then provisions the server.
The following table shows a summary of resource usage by UCS Provision Jobs.
UCS Provision Jobs make demands on the UCS Fabric Interconnect to accomplish the actual construction of the virtual guest.
