Converged infrastructure Traditional infrastructure can be the right choice, but for many organizations, it has some serious drawbacks. Such drawbacks generally revolve around the time it takes to get a complete infrastructure operational, particularly when you buy things from different vendors and cobble them all together. There is the potential for interoperability issues that can take a lot of time to resolve, which means that the time‐ to‐value for the infrastructure purchase might be extended. Time‐to‐value is a measure of how long it takes from purchase order to operation. Most companies don't want a long figure here and want to be able to begin to gain benefit from their investments in an expedited manner. This is where converged infrastructure, such as HPE ConvergedSystem, comes in. Converged infrastructure com- bines storage, servers, and networking into a single purchase from a single vendor so that you know everything will work exactly as it should. Converged infrastructure is often a simple bundling of existing products, but with heavy testing. Further, many converged systems arrive in your data center fully racked and cabled. You simply plug them in to your net- work and turn on the power. Such solutions can massively reduce the time‐to‐value, and you can start running your business workloads almost immediately. Hyperconverged infrastructure But, maybe you don't want a converged solution or you want to start a bit smaller and be able to grow in more granular steps as your workload needs change. Or, perhaps you're looking for a solution that doesn't just transform the buying process, but that can also transform how you operate the infrastructure. Enter hyperconverged infrastructure. Hyperconverged infrastructure is a data center model in which a simple, efficient, software‐defined platform combines everything below the hypervisor — compute, storage, and data services — into a single appliance. The software on each appliance communicates with the software on all the other appliances in the hyperconverged cluster and creates
