Any other questions?

Here you will find answers to various questions on the topic of our Managed Services.

What are the advantages of outsourcing?

The term outsourcing refers to the transfer of activities previously performed in-house to external service providers. The advantages are more flexibility, agility and scalability, together with redundancies with in-house capacities. It also helps to compensate for the lack of skilled IT staff. Scalability and agility are of crucial importance in data centers. The required components begin to age almost as soon as they are installed. This is where specialists are needed.

What service packages does Rosenberger OSI offer?

We offer our customers a Service Level Agreement, that is to say a framework agreement for recurrent services. The aim is to provide our customers with transparent verification criteria by precisely describing promised performance characteristics such as performance scope, reaction time and speed of resolution of problems. These are agreed on individually in the light of requirements.

How does collaboration with other subcontractors function?

During high-level IT room planning, the availability of electricity and air conditioning are considered within the framework of a preliminary capacity examination. If required, we create the interface to the corresponding technical building equipment activities and define subsequent requirements.

Why is outsourcing worthwhile in the warehouse management field?

We manage the equipment necessary for operation for you in the corresponding stores, either at your premises at the data center or, if there is insufficient space, at our own premises. Ideally, our service technicians only bring the required quantity of equipment from storage to the data center with them. This prevents waste and superfluous fire loads and saves space.

Why is end-to-end documentation so important?

In everyday operation, it is only possible to plan as well as the existing cabling has been documented. The key here is a good software solution and the rapid entry of the cabling and/or the seamless documentation of any MACs (move/add/changes) as they occur.
