Gone are the days of struggling with complex hardware, software and data integration, and piecing together makeshift data centre systems. Convergence has arrived — in the form of hyper-converged and converged IT infrastructures –with greater and effective benefits for your data centre systems. Streamlining of management, scalability and expenditure are all the dynamics concerned when an enterprise has to decide on whether or not to go for converged IT infrastructure vs. Hyperconvergence.
Converged IT infrastructure brings together compute, storage, server virtualization and networking into a single framework which can be managed centrally. Depending on the type of configuration you buy from different vendors, this can include VDI management too. Hyper-converged infrastructure (HCI) adds close-fitting integration between additional components through software. Both CI and HCI helps decrease the complexities involved in deploying VDI, an innovation that has been welcomed by those looking to virtualize desktops.

Enterprises appreciate greater value and efficacy when deploying fully integrated compute, storage and network gear as a single component. Convergence IT infrastructure has progressed much further than just the bundling and pre-integrating a collection of various manufacturers’ data centre IT systems offerings. Vendors from traditional IT areas such as storage and servers or virtualization, as well as specialized establishments, have incorporated the idea of hyper-converged infrastructure (HCI). Vendors are vying to be the sole source for all enterprise computing necessities.
Choosing between converged IT infrastructure and Hyperconvergence
Converged infrastructure syndicate server and storage modules in a single platform efficiently eliminate the need for a devoted storage area network (SAN)-based storage. These systems make available a confined single resource pool solution, proposing streamlined management and quicker time intervals for deployment. They have successfully virtualized the storage layer allowing it to function in the virtualization platform. Largely, the acquisition price is lesser, and the management simplified. The overall resource utilization is greater, although there are some limitations:
- The systems consist of only the server and storage resource components.
- Resource ratios (e.g. CPU: storage: network) are predefined or fixed, making them not very flexible than some companies may have need of.
- The products cannot always be used by prevailing infrastructure or from existing legacy systems.
Due to these limitations, converged infrastructure systems don’t proficiently cater to the performance glitches in the legacy infrastructure. Similarly, on the data front, the systems do not address all data difficulties, since not all data efficiency appliances are converged.
Hyper-converged infrastructure takes converged infrastructure to the next level in the data centre, delivering a variety of benefits. Hyperconvergence signifies the rational next step in the progression of infrastructure convergence. Hyper-converged infrastructure provides simplification and savings by combining all essential functionalities into one infrastructure stack that functions on an effective pool of resources. The fundamental data architecture has been entirely reinvented, allowing data management to be streamlined.
Hyperconvergence adds to the benefits of convergence, together with a single shared resource pool and goes beyond servers and storage. Some of the services it brings into the convergence fold are data protection (say backup or replication), WAN optimization, SSD arrays, Public cloud gateways, Replication software, deduplication alliances, etc.
The flexibility of Hyperconvergence makes it more scalable and cost-effective than converged infrastructure, enabling the addition of blocks of compute and storage as and when required. The upfront expenditures of both technologies are sharp, but can definitely pay off in the long run.
