VMware NSX Use Case – Simplifying Disaster Recovery (Part 1)

Nicolas Vermandé (VCDX#055) is practice lead for Private Cloud & Infrastructure  at Kelway, a VMware partner. Nicolas covers the Software-Defined Data Center on his blog www.my-sddc.om,

This series of posts describes a specific use case for VMware NSX in the context of Disaster Recovery. The goal is to demonstrate the routing and programmability capabilities through a lab scenario. This first part presents the NSX components and details the use case. The second part will show how to deploy the lab and the third part will deal with APIs and show how to use python to execute REST API calls to recreate the required NSX components at the recovery site.

Introduction

When considering dual datacenter strategy with VMs recovery in mind, one important decision is whether to adopt an active/active or active/standby model. The former is generally much more complex to manage because it requires double the work in terms of procedures, testing and change controls. In addition, capacity management becomes challenging as you need to accommodate physical resources to be able to to run all workloads within whatever site. On top of that, stretched VLANs are sometimes deployed across datacenters so that recovered VMs can keep their IP addresses. This Continue reading
