Consolidating servers means reduce the number of computers in the server farm keeping unaltered the services offered. Virtualization is the main tool used for server consolidation. It allows running multiple operating systems on the same machine at the same time. It is also possible to concentrate on the same chassis multiple servers using the blade technology. The multiple advantages of a Server Consolidation project are:- Saving on the electricity bill.
With a Server Consolidation project you reduce the number of physical computers making the electricity consumption drop. The minor use of electricity due to the lower number of servers and the consequent lower use of cooling allow strong savings on company costs. - Simplification in management, maintenance and upgrade of servers
Any action on consolidated servers is simpler, faster and more secure compared to the execution of the same operations on normal servers. This is due to the flexibility of a virtual system compared to a physical one. Backup times, environment migration, data and system recovery are very short to the point of permitting close execution of operations that previously lasted complete working days. This allows the company to free resources and reduce outsourcing costs.
- Reduce space occupied by computers in the server farm
Replace multiple computers with a blade system reduces automatically space consumptions guaranteeing system scalability. Every system administrator knows how precious space is in their server farms. Upgrading the system with a new server or with other devices can be a problem due to lack of physical space without mentioning that the upgrade needs to be supported by the cooling and power system.
A consolidated server is very fast and easy to recover in case of malfunction and upgrade. For example if there was a hardware failure the virtual machine can reboot quickly on new hardware without service interruption.
Furthermore all maintenance tasks can be made without rebooting the machine avoiding long downtimes on traditional systems. In conclusion a good consolidation plan can bring:
Our OfferPolimatica provides you with technical personnel expert in Server Consolidation, virtualization and blade technology to design and implement the consolidation of your server farm.
Our projects are based on the technology offered by VMWare, global leader in this field. We are an enterprise partner of VMware and have qualified and certified personnel.
In each project we help our customer in the choice of technologies to use, searching for the best solution in terms of cost, performance and reliability.
We assist our customers in all stages of the project with a tested methodology structured as follows:- Analysis of the whole infrastructure to define the perimeter
- Inventory of the server infrastructure in the perimeter
- Monitoring of workloads on each server
- Study and analysis of reports generated by the monitoring process
- Generation of a consolidation plan
- Choice of the most suitable technologies
- Hardware configuration of the host server
- Virtualization of physical servers currently in the perimeter
- Monitoring of the new virtual infrastructure
- Fine tuning of the new server parameters
- Non-regression test to check the correct implementation of the consolidation plan
