• interoperability and compatibility requirements:
  • Hypervisors - VMware vSphere 4.1 or later
• list localization and internationalization specifications 
  • UI changes in "Add Cluster" wizard. See the section "UI Flow".
• explain the impact and possible upgrade/migration solution introduced by the feature 
• explain performance & scalability implications when feature is used from small scale to large scale
  • In case of vSphere 4.1 dvPortGroup need to be created with specific number of dvPorts. In large scale deployment optimum use of dvPorts may not be possible due to this pre-allocation. In case of vSphere 5.0 the autoexpand feature helps in auto increment of number of dvPorts.
  • Network switches (including the vSwitch in ESXi host) keep a distinct forwarding table for each VLAN; this could lead to an increased overhead in packet forwarding when a considerable number of isolated networks, each one with a significant number of virtual machines, is configured in a data centre.

• explain marketing specifications
  • Supporting VMware dvSwitch entitle CloudStack
  • * For better monitoring and simpler administration of the virtual network infrastructure in Cloud.
  • * Configuration and management of several vSwitches across large deployments in tedious.
  • * Seamless network vMotion support
  • * Better traffic shaping and efficient network bandwidth utilization is possible.
