Only through the optimal interaction between hardware, network, SAN, operating system, database and
those on it coordinated application, ultimately determine the availability class.
With an increase in availability, you gain a significantly higher level of user satisfaction.
However, the quality of all the system components used plays an important role in this.
Here we can help you significantly in all situations with our many years of experience.
