Hyper-Converged Infrstructure
Hyper-convergence is an IT framework that combines storage, computing and networking into a single system in an effort to reduce data center complexity and increase scalability. The use of commodity hardware, supported by a single vendor, yields an infrastructure that's designed to be more flexible and simpler to manage than traditional enterprise storage infrastructure. For IT leaders who are embarking on data center modernization projects, hyper convergence can provide the agility of public cloud infrastructure without relinquishing control of hardware on their own premises.
The main difference between converged and hyper-converged are: -
Converged infrastructure involves a preconfigured package of software and hardware in a single system for simplified management. But with a converged infrastructure, the compute, storage, and networking components are discrete and can be separated. In a hyper converged environment, the components can’t be separated; the software-defined elements are implemented virtually, with seamless integration into the hypervisor environment. This allows organizations to easily expand capacity by deploying additional modules.
Advantages: -
1.The star of the HCI approach is software-defined storage (SDS) technology. SDS aggregates all existing hard drives within a cluster and represents them as a single, highly available, highly redundant storage capacity pool.
2. Optimizing infrastructure costs is another major appeal of HCI, which can drive better performance while at the same time reducing TCO.
3. HCI is well-suited to helping organizations modernize applications development and deployment.
4. Last but not least, HCI can help enterprises move aggressively toward more flexible infrastructure and data centers.
5.Automated Infrastructure hyper converged infrastructure works on the principles of the software-defined data centre (SDDC), where everything including storage, servers and supporting services are virtualized
Disadvantages :-
1. Storage capacity cannot be extended.
2. Performance of the system may become inefficient as more systems get connected.
3. It supports only virtualized storage system if any system is not virtualized it will not support those systems.
4. Even though the hardware is cheap but to run it the software is costly
conclusion:-
Though there are disadvantages of this infrastructure but we have more advantages of it and as less machine is used it also helps in reduction of green house effect and the deployment of data center makes easy and flexible so it is more recommended to use and also useful for a big organizations for datacenter deployment.
