Migration to the hypervisor version Microsoft Hyper-V Server 2008 R2 has made it possible to take the existing fault-resistant cluster to a new level of functionality, reliability, and performance, while the implementation of Microsoft System Center Virtual
Machine Manager 2008 R2 has provided all that is needed to develop a virtual infrastructure.
||We always strive to use the latest technologies in our work, including those implemented in Microsoft products. We were among the first in the region to have implemented a fault-resistant cluster based on Hyper-V technology. However,
as the new version of the hypervisor was released, we realized that we had an opportunity to considerably simplify the process of system operation while simultaneously improving its efficiency and reliability,

The Kirov regional public healthcare institution Medical Information Analysis Center (MIAC) is tasked with coordinating the development of information technologies at healthcare institutions of the Kirov Region. The mission of MIAC is to create a unified system
for aggregating, processing, consolidating, and analyzing medical statistics to enable dynamic assessment of the state of public health in the region. One of its chief tasks is providing quality medical and economic information in a timely fashion.
For a number of years, the company has been using a virtualization cluster running on Microsoft Windows Server 2008. Yet it posed a number of difficulties, such as the inability to perform hardware maintenance without shutting down virtual machines, inefficient
utilization of disk space of data storage systems, etc. Further growth of the virtual infrastructure was slowed down by the absence of management and migration tools.
The company needed to upgrade its fault-resistant cluster with minimum downtime of IT services and ensure easy management of the virtual infrastructure and processes of migrating existing server loads into the virtual environment.
Following analysis, a detailed cluster upgrade plan was prepared. It was decided to change the hardware configuration and perform hardware servicing. The free version of Microsoft Hyper-V Server 2008 R2 was selected as the operating system for the cluster nodes.
"We offered them to use the free version of the hypervisor, since the Client already had licenses for Windows Server 2008. This solution afforded costs savings for the project".

The project took 2 weeks to implement and involved several stages. Since the original cluster worked in the "active - passive" mode, the passive node of the cluster was taken out of operation first. It hardware was inspected, and an operating system was installed
and configured on it.
The virtual machines were then migrated to the new node. Migration was accompanied by restructuring of the data storage system to enable more efficient utilization of resources.
The next stage involved upgrading the remaining node and deploying a fault-resistant cluster. Virtual machines were switched to high accessibility mode.
Once cluster operation has been tested, the virtual infrastructure management solution Microsoft System Center Virtual Machine Manager 2008 R2 was deployed, a library of virtual machine images and software setup packages formed, and several test migrations
from the physical environment to the virtual environment performed.
The project has accomplished the primary goal of improving the reliability, manageability, and flexibility of the system while simultaneously reducing infrastructure servicing costs.
Use of Microsoft Hyper-V Server 2008 R2 has made it possible to:
- Reduce budget spending on the project by saving on licenses
- Eliminate all downtime of existing IT services during equipment maintenance owing to Live Migration technology
- Make more efficient use of resources of the data storage system by means of the Cluster Shared Volume technology
The implementation of Microsoft System Center Virtual Machine Manager 2008 R2 made it possible to roll out new services in next to no time and transfer existing loads to the virtual environment at minimum cost. All infrastructure elements are controlled using
a single tool, which reduces maintenanc costs.
"This project has considerably improved the reliability and manageability of our infrastructure, which we need to set up a modern center for collecting and processing data that arrives from the territorially
distributed system of healthcare institutions in the region,"
