Why would you use converged server infrastructure architecture for your Cloud?

In the NIST definition of Cloud Computing, virtualization and elasticity are listed as requirements. Virtualization is made possible by implementing hypervisors on servers, thereby allowing for multiple instances of operating systems to lie on a single server and sort of giving the impressions that you have many many servers available. Before this happened, you’d typically have a single operating system on a single server, and once that server is used to capacity, the only way to horizontally scale (to add capacity) would be to physically add more servers to your cluster.
Adding more servers meant you’d need to connect the other parts of the infrastructure stack, i.e. network components and storage components to the newly added servers – which can be a pain when you are scaling rapidly.

Enter, converged architectures which are integrated stacks of storage, network and servers, with virtualization hypervisors automatically built on top. Their advantage is that when you need to horizontally scale out, you just have the hypervisor automatically govern the resources of the infrastructure stack – think of the power of this for a moment…You have a single point of control which greatly simplifies how you manage your infrastructure, which by the way, results in lower operational expenditures and lower resource requirements.

Read here for a great case study.
