Virtualisation and clusters

At Stemil we know that reliable server solutions and virtualisation sit at the heart of every modern IT infrastructure. Our specialists design, deploy and manage physical and virtual servers, hypervisors (VMware, Hyper-V, Proxmox), high-availability clusters and load-balancing solutions. We optimise resources, keep you running even through hardware failures, and make migration and capacity expansion straightforward.

For our team it matters a great deal that a momentary fault never interrupts your work. Virtualisation cuts the cost of hardware, energy and space, while clusters guarantee business continuity. You get a flexible, easy-to-manage and well-understood environment, ready for growth and heavier workloads.

Server virtualisation is the process by which Stemil turns your physical servers into virtual machines. This optimises resources and raises the efficiency of your IT infrastructure.

Server virtualisation happens in several stages:

• first, an audit of the existing IT infrastructure
• then the results are analysed and a concept is developed
• a plan is drawn up for migrating from physical to virtual servers
• the migration itself is carried out
• finally, testing and optimisation

Every stage is carried out in close cooperation with your technical team and configured around your needs. The results of each stage are agreed with you, we provide monitoring throughout, and we prepare a backup of your data in case migration is required.

When critical infrastructure (systems that must never stop) is virtualised, it can be organised into a cluster. A cluster links several servers so that if one fails, the others automatically take over its work. A single faulty component therefore does not stop the whole system, and the work is handed over cleanly.
