Hi all, In this blog I wanted to share a lessons learned when using VMware NSX with Zerto for disaster recovery purposes. Just a bit of background first, I am using for this blogpost a 3-site architecture: Management site: here vSphere, NSX manager and the Zerto Virtual Manager are hosted. This site manages both Site A and Site B. Site A: Our production site with a web and an application server. Site B: Our DR site for fail-over purposes. Background For Disaster Recovery (DR) we use Zerto to protect both our WEB and APP servers. Zerto copies the data from both VM’s from Site A to Site B, so in case site A becomes unavailable we can recover the servers. To protect the servers from a network and security perspective we use VMware NSX and leverage the Distributed Firewall (DFW) and NSXs’ micro-segmentation capabilities. For our application servers we create a...
Hi All, In this blog I wanted to share a few of my experiences when migrating from an on premise datacenter environment to a private (metro) cloud platform. A lot of enterprises and even small to medium businesses use multiple datacentres for Disaster Recovery (DR) purposes. In many cases these datacentres are local within the same metropolitan area. The distances between those datacentres is usually set between 10 km and 100 km to ensure floods, power outages or other (small) disasters don’t affect services. (Here in Brisbane after our 2011 flood experience this has become pretty much the rule of thumb). Consider the design below when the following applies: you have low latency/high bandwidth connectivity between data centers you don't have/want a stretched storage cluster you need to use VLAN to VXLAN bridging to migrate workloads. (no cross-vcenter deployment) A quick walk though of the diagram. The top bit (in blue) shows a new ...
