Today, as IT systems become more and more integrally connected with business requirements, the number of servers is increasing to match business growth and the addition of new services and departments.
File servers, mail servers and Web servers are often purchased or added independently as they become necessary for different departments and are then individually managed by each department.
While this has the advantage of making adding servers easier for individual departments, system administrators and inventory managers find themselves constantly stressed by security concerns or by determining how many servers are running across the organization. Server management has become overwhelming and understanding an entire IT system has become extraordinarily difficult.
In addition to the distressing fact that understanding IT operations is often physically impossible, the costs of operations and management for hidden aspects of systems, combined with the burden on those in charge, have a negative effect on efforts to reduce the total cost of ownership. Instead of helping businesses, IT systems can become a source of endless headaches and could actually impede growth.
Because server consolidation delivers effective management of server resources, it is generating great interest as a one-step method to solve the many problems shared by all industries as a result of server proliferation.
Consolidating multiple decentralized servers makes it possible to centralize operations management. Not only does this improve operations management for IT professionals and cut operating costs for business management, it also offers many other advantages including more effective utilization of server resources, smoother system updates, and improved security.
Select the most appropriate server consolidation method based on your objectives and on system usage and scale.
File servers, Web servers, and application servers scattered throughout the office are consolidated on one large server while service delivery does not change. Based on actual usage patterns, average system loads are increased and resources can be allocated to each service when they are needed. One advantage of this approach is that system utilization can be optimized to allocate the bulk of system resources to the applications and services that need them.
Servers scattered among branch offices or on different floors are moved to one location such as a data center or company headquarters, enabling consolidated management. Centralizing the placement of servers in one location aids asset management and also allows a designated manager to carry out maintenance and other duties at one location, even for initial installation. There are also obvious security advantages in consolidating servers from more freely accessible locations around your office or various departments.
In this consolidation scheme, a group of servers in separate physical locations are treated and operated as one logically integrated system. In most cases, operations tools and centralized management will allow scattered onsite servers to be treated as one virtually integrated system despite their physical distance. Furthermore, the need for a manager with specialized technology at each installation location is eliminated.
The NEC Express5800 Series of servers can flexibly deliver an entire range of server consolidation options to meet your individual needs.
