With the term hyperconvergence means a type of IT infrastructure having a hardware, or software architecture, capable of Manage computing, storage and network resources in a single integrated platform. This type of infrastructure is designed to simplify management, improve operational efficiency and offer greater flexibility in the deployment and management of IT resources.

Most hyperconverged systems require at least three hardware nodes that can be further expanded by adding more. A group of nodes is referred to as a cluster.

There are different types of hyperconvergence solutions, each with its own characteristics and advantages. The choice among these types depends on the specific needs of the organization, its existing infrastructure, workload requirements and management preferences.

Each type of hyperconvergence has its own advantages and considerations, and the choice will depend on various factors , including performance requirements, flexibility, cost, and business objectives.

Distributed hyperconvergence, also called scale-out, is an approach to IT infrastructure in which compute, storage, and network resources are integrated and scale horizontally. This means that overall resources can be increased by adding new nodes or appliances, rather than having to perform vertical upgrades on individual components.

Scale-out hyperconvergence solutions are designed to simplify IT infrastructure management, reducing operational complexity and improving efficiency. The scale-out approach makes it easy to expand overall capacity by adding new units without disrupting existing operations.

This concept is particularly relevant in the contexts of data center and of cloud computing, where flexibility and scalability are crucial to meet changing needs. Scale-out hyperconvergence is often associated with technologies such as virtualization, which enables better resource management and more efficient resource utilization.

The HA Metro Cluster hyperconvergence system consists of two OpenStor Storage Servers interconnected with high-speed, low-latency 40GbE LAN card. VMware ESXi is present on both, and an Open-E JovianDSS Virtual Appliance Storage (VSA) is installed on each unit.

Thanks to the Advance HA METRO CLUSTER service with Automatic Failover, both storage units work in synchronous mirroring, that is, every write made to the first storage unit also occurs simultaneously on the second, and vice versa.

In case one of the two storage failures, thanks to the Automatic Failover service, the remaining one instantly publishes the volumes (iSCSI or NFS) seamlessly guaranteeing their high data availability, while depending on the VMware licensing used it can guarantee the HA of the VMs.

Hyperconvergence (HCI) systems offer numerous benefits for businesses, including improved scalability and management of IT services and a Significant reduction in costs. especially when expansion of resources is needed as a result of business growth.

Indeed, the scalability of hyperconverged infrastructure, both horizontal and vertical ,greatly simplifies budget forecasting, enabling companies to be able to plan their IT investments more accurately, reducing the risk of overestimating or underestimating costs.

Horizontal scalability is about adding new nodes to the infrastructure allowing for increased compute, storage and network resources.

Vertical scalability, on the other hand, allows the above resources of each individual node belonging to the infrastructure to be upgraded in order to improve its performance without having to replace the existing hardware.

The possibility of the described expansions, which allow for increases in computing capacity and storage capacity, proves to be very convenient, especially when infrastructure needs to be scaled up as a result of business growth.
