Hyper Converged Infrastructure
Hyper-converged infrastructure (HCI) combines storage, networking resources and calculate, in a single “building block” and accepts Software Defined Everything approach. Software-Defined Storage (SDS) mass eliminates the need for the patented storage hardware, considerably reducing costs subsequently dedicated storage hardware is no longer needed. The storage is controlled at the OS or Hypervisor layer with the help of virtual storage controllers. These virtual controllers run on every bulge within the cluster ensuring cohesive storage management, better resiliency, and failover capabilities. Software-Defined Networking (SDN) makes network management alert and flexible by providing a centralized interface allowing administrators to cope traffic and quickly dispense network resources where they are needed. Such cohesive technologies dramatically improve IT infrastructure efficiency by automating provisioning and configuration of the entire networking mass
Why hyper converged infrastructure matters?
Hyperconverged infrastructure simplifies the work of system administrators by allowing them to manage and monitor the entire IT infrastructure from a “single pane of glass”.
Such infrastructure provides higher flexibility, allowing not only to Scale Up by adding more drives, memory, or CPUs, but also to scale-out by adding additional cluster nodes. More to say, HCI deployment and operational costs become significantly lower with less hardware to purchase and maintain
Hyperconverged architecture simplifies management by combining all nodes into a single resource pool. This allows managing aggregated resources across individual nodes from a single pane of glass instead of having a set of separate management interfaces for different components.
Contrasting converged systems, which necessitate huge investments to scale out, solutions from HCI dealers have a much smaller step size, sinking costs for infrastructure development. HCI systems are also built around the low-cost commodity x86 hardware significantly lowering upfront and operational costs.
