Planning for disaster recovery is an essential practice among IT organizations who are designing their environments to support business-critical applications. Each new application or instance must be deployed with enough resiliency to overcome common hazards such as floods, fire, power failures, and human error.
To design a resilient IT infrastructure, we must first consider the datacenter site, or sites. If there is a single datacenter site, simply duplicating the IT infrastructure will not provide the desired resiliency if the failure event impacts the entire site. If we deploy our business applications across more than one site, we would need mechanisms to replicate the information across sites. In the event of a site loss, even with information replicated, we would still need to introduce processes or tools that would help during the subsequent failover and failback operations.
The need for a resilient IT architecture is shared across all industries and geographies. It is manifested in IT architecture proposals that should consider factors such as:
In this context, we propose a solution to address this business need with a highly effective and function-rich architecture featuring Dell EMC PowerOne with Dell EMC Symmetrix Remote Data Facility (SRDF) and VMware Site Recovery Manager.
