With a number of my recent consulting engagements, I have seen an increasing demand for host-based replication solutions for data replication. In a few of my recent projects, I have implemented VMware Site Recovery Manager in combination with VMware vSphere Replication.
I have written about vSphere Replication (VR) in the past and I am not surprised that a number of VMware customers are shifting focus from a storage-based replication solution to a host-based replication solution due to the cost-benefit and flexibility that comes with such a solution.
In my projects I started with replicating simple web servers to DR site using VR; now customers are discussing database servers, exchange, and other critical workloads to be replicated using vSphere Replication. With an out-of-the-box integration with a solution such a as VMware Site Recovery Manager, building a DR environment for your virtualized datacenter has become extremely simple and cost effective.
The configuration of the replication appliance and SRM is as easy as clicking NEXT, NEXT, FINISH; however, the most common challenge has been around estimating the bandwidth requirements from Protected Site to Recovery Site for the replication of workloads. One of the most commonly asked question is: “How do I calculate the bandwidth requirements for replication?” Continue reading
