Virtual desktop infrastructure is the best-known use case for hyper-convergence because hyper-converged technology can simplify a VDI strategy. Much of this simplification stems from hyper-converged products that are fully supported by virtualization vendors. Because these products are specifically designed to work with the virtualization platforms used in a VDI strategy, compatibility is guaranteed.
Absolute compatibility has additional benefits, such as no-hassle technical support. Most IT professionals have occasionally run into a situation in which a call to a support line results in vendor finger-pointing: A hardware vendor might blame a software vendor, while the software vendor blames the problem on hardware. In a hyper-converged infrastructure environment, the hardware and software are certified to work together, and IT professionals can use a single point of contact for their technical support needs.
Before hyper-converged infrastructure became the go-to technology in a VDI strategy plan, data storage was often an issue for organizations deciding to take the plunge and adopt VDI. First, there was the complexity. An organization typically had to deploy a SAN or some other type of shared storage to meet the requirements of the VDI platform. These storage requirements led to increased cost and complexity. More importantly, administrators often discovered that their VDI environments did not perform as well as they would have liked because of issues like storage latency and resource contention resulting from multiple virtual desktops competing for storage IOPS or bandwidth.
Hyper-converged infrastructure includes storage as an integrated component. As such, IT pros executing a VDI strategy do not have to worry about the costs or complexities associated with implementing external shared storage.
Perhaps the greatest benefit a hyper-converged infrastructure provides for VDI environments is scalability. IT pros do not have to worry about scaling individual components such as storage or compute. When the VDI environment grows, and more capacity is required, additional nodes can be easily added to the hyper-converged infrastructure.
