Server system ends to be just personal computer, complete with ECC (Error Checking and Correcting code) memory, which allows correcting of 4bytes mistakes, with RAID controller and disk massive. Now, with rising of quality of services, unification of services and applications, server infrastructure – is specially developed complex providing the highest level of fail-safety feature and effectiveness.
Besides the functional requirements to modern servers, there are additional requirements on expendability, computing and hardware redundancy and managing of server infrastructure. Requirements to modern systems rise dynamically, demanding more informational support. Companies want to expand capacity of servers to save investments.
Server solutions should have the capability to expand the volume of memory, network interfaces, processes, ventilation units, the ability to install additional disk capacity for raising effectiveness and fail-safety feature of server infrastructure using initial investments.
