• SDN VE does not require the user to enable IP multicast in the physical network


System Networking

IBM SDN VE Built for large scale to serve large, dynamic, automated data centers

• First release will support 16000 virtual networks, Architected to support 16 million virtual networks• First release will support 128000 end stations (VMs), Architected to support millions of end stations• Highly distributed and federated addresses learning and dissemination • Does not require multi cast support for control plane

Network connectivity service with templates for using network as a service

Built to support automated provisioning of network• RESTful and Quantum APIs

Built in basic IP gateway feature for ease of network set up and performance• Does not need an external IP gateway for communication between virtual networks

Cluster based highly available solution• User configurable clustering solution for desired level of High Availability• Highly available gateways

Native Multi-Platform solution• Native switching component in the hypervisor for high performance

Benefits Key Features

Faster time to value Deploy applications and network connectivity services faster Create networks as quickly as virtual servers through

automation

Reduce OPEX Centralized network creation No change needed to physical infrastructure Automate VM movement along with policies and configurations Multiple hypervisor support for consistent virtual networking

Scale up or down Support up to 16 million virtual LANs Create and de-allocate networks as needed

Enhance security Eliminate error prone manual configuration when moving VMs Logically separate virtual networks for multi-tenancy

Enabling the era of virtual networking

Provision multiple virtual networks on a common physical infrastructure using IBM’s virtual overlay technology

IBM SDN VE is a multi-hypervisor solution


System Networking

Cut network provisioning from days to minutes Secure VM mobility across Layer 2, Layer 3 networks and data centers
