6 Network Virtualization with Dell Infrastructure and VMware NSX | Version 1.2
To stay concise and focused on the application of network
virtualization, this whitepaper will focus on solution #1: Dell
Infrastructure with VMware NSX-vSphere. Solution #2:
Dell Infrastructure with VMware NSX-MH is a viable option
for those who have multi-hypervisor environments or desire
to leverage hardware-based NSX L2 Gateway.
For specific installation requirements and detailed deployment steps please see the Dell Infrastructure with
VMware NSX Deployment Guide.
3 Dell Open Networking Differentiators
Dell believes in an open model for networking and solutions. Thus, Dell offers customers choice of OS on
supported Dell Networking switches like the Dell S4810 and Dell S6000. Customers can choose either the
typical robust, feature-full Dell Networking Operating System or Cumulus Linux. Both Dell and Cumulus
operating systems are supported within a Dell VMware NSX solution.
Cumulus is a Linux software distribution that runs on Dell Networking hardware to allow for ease of
integration in a Linux environment, use of Linux applications and automation tools, and an open source
approach to networking applications.
The Dell Networking Operating System is a resilient, hardened OS and proven in the industry. Dell
continues to innovate and incorporate the latest technology demands by customers into its products.
Some of these technologies include but are not limited to:
Data Center Bridging provides a lossless fabric for a converged LAN/SAN network
VRF-lite provides for mult-tenancy and use of overlapping IP addresses at the switch level
Virtual Link Trunking (VLT) for Active-Active links from a server/switch to two different switches
VXLAN protocol support for creating logical network overlays
Hardware-based NSX L2 Gateway support for bridging between logical and physical networks
OpenFlow protocol support for OpenFlow based SDN solutions
Additionally, Dell provides a complete end-to-end infrastructure whether converged or non-converged
and allows for the management of such infrastructure with Dell Active Fabric Manager (AFM) and Dell
OpenManage Network Manager (OMNM).
Dell OMNM automates labor-intensive tasks while monitoring and managing Dell network switches. Dell
AFM provides simplified configuration, management and monitoring of Dell networking components.
Starting with AFM 2.0, Dell introduced the command line interface functionality for VMware vSphere
Distributed Switch (VDS). Users can now access and view VDS information from the AFM CLI; with this
functionality, Dell is helping bridge visibility between the virtual and physical environments.
