Chapter 5 Working with Configurations

Cloning Configurations

Stage Managerallowsyoutocreatelinkedclonesandfullclonesofanundeployed

configuration.

Alinkedcloneoperationgeneratesa“quick”copybycreatingadeltadiskinsteadof

copyinganentirevirtualharddisk.Thisoperationaddressesvirtualmachine

changesbutreferringbacktoachainofdeltadisks.Foreachclone,Stage Manager

freezestheoriginaldeltadiskandcreatesanewone.

Afullcloneoperationcopiesallofthedeltadisksandthebasediskandconsolidates

themintoanewbasedisk.Theoriginalbasediskremains

unchanged.

Typically,youdonotcreatefullclonesexceptundertheseconditions:

 Youneedtodismantlethestorageandmovetheconfigurationtoadifferentserver.

 Youwanttomaximizeperformanceforvirtualmachines(forexample,forcertain

production‐levelvirtualmachines).

Afull‐cloneoperationtakesalongertimethanalinked‐cloneoperation.

Inafencedconfiguration,virtualmachinesretainthesameIPaddresswithinthefence.

Stage ManagerassignsnewexternalIPaddressesforcommunicationoutside

thefence.

Eachtimeyoudeployafencedconfiguration,Stage ManagerassignsnewexternalIP

addressesfromtheStage ManagerIPaddresspool.Stage ManagerreturnstheIP

addressestothepoolwhenthefencedconfigurationisundeployed.Stage Manager

doesnotreturntheIPaddressofalinkedclonetotheIPpool

untilthevirtualmachine

andallitscopiesaredeleted.

Whenyoucreateaeitheralinkedorfullclone,Stage Managerassignsthesame
