- Virtualize networks without changing the physical networking infrastructure
- Simplify and automate network provisioning
- Increase server utilization
- Deploy applications more quickly
- Create networks as quickly as virtual servers through automation
- Create and deallocate networks as needed
- Logically separate virtual networks with IP and MAC address reuse capability for multi-tenancy
Data center networks today need to support an explosion of virtualization. While advances in server and storage virtualization allow compute and storage resources to be provisioned in a matter of minutes, provisioning network resources still takes a long time and involves manual processes. Advances in networking are making networks more responsive to today’s business needs. However, even with all of the recent advances, the physical network remains a bottleneck limiting the speed of business value.
IBM Software Defined Network for Virtual Environments creates a more responsive network by creating 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. This approach provides several advantages:
- 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.
- Allows virtual machines to interact with each other via virtual networks
- Enables creation of virtual networks as quickly as virtual machines
- Scales to 16000 virtual networks
- Works with existing networks—does not require specific network hardware
- Uses clustering and high availability technology for redundancy and failover
- RESTful API for third party management application integration
- Supports network policies for virtual switches
- Independent address space allows safe reuse of IP/MAC addresses
