workloads that occur infrequently. Frequently processor utilization in these scenarios is less than 30%. Storage utilization although better, is still only at about 50%. When multiple workloads are consolidated on a single server, there is an excellent opportunity to reduce total capacity, since peak workloads for one application may not coincide with peak workloads of another.
Thus, consolidating workloads or applications can reduce the total amount of excess capacity that must be reserved.
IT organizations use server consolidation to reduce the number of physical servers under management for an optimized IT infrastructure.
Server Consolidation optimizes IT resources, such as servers, storage, network, supporting staff and real estate, allowing information to be continuously accessible, while meeting the changing needs of the IT organization.
Virtusation
Among the leading business challenges confronting CIOs and IT managers today are :
- Cost-effective utilization of IT infrastructure.
- Responsiveness in supporting new business initiatives.
- Flexibility in adapting to organizational changes.
Driving an additional sense of urgency is the continued climate of IT budget constraints and more stringent regulatory requirements. Virtualization is a fundamental technological innovation that allows skilled IT managers to deploy creative solutions to such business challenges.
Virtualization allows multiple virtual machines, with heterogeneous operating systems to run in isolation, side-by-side on the same physical machine. Each virtual machine has its own set of virtual hardware (e.g., RAM, CPU, NIC, etc.) upon which an operating system and applications are loaded. The operating system sees a consistent, normalized set of hardware regardless of the actual physical hardware components. Click here to know more>>
