IBM SDN VE
IBM Software Defined Network for Virtual Environments creates a virtual network for virtual machines. This virtual network is decoupled and isolated from the physical network much like a virtual machine is decoupled and isolated from its host server hardware.
IBM touts several advantages with this approach:
- Virtual networks can be created without any changes to the existing network.
- Since the physical network does not have to be changed, it can be wired once.
- Provisioning and administration can be simplified and automated.
- IP and MAC addresses can be reused, permitting logical separation of networks for multi-tenancy.
