Operating
System Windows Server 2008
R2 Enterprise provides an uninterrupted functionality, safety based on the
newest technologies and high zooming what is necessary for enlargement of
critically important applications support.
Also it allows you to virtualize the equipment inexpensively and
effectively.
Windows Server 2008 R2 Enterprise is an optimal operating system for the
servers of the managing the web, exchanging messages, inventory, customer
service and data applications. It supports all of the functional capabilities of Windows Server 2008 R2
Standard and also has the following advantages.
High Accessibility.
Organization of the 24-hour customer, provider and partner service
without failing is a key factor of the global business. The permanent access to
system and data is needed by dial-up users, providers and partners. Downtime in
service lead to the reduction of productivity and opportunities are lost.
Thanks to the tools such as fault-tolerant clusters, Server Core,
fault-tolerant synchronization of the memory and Distributed File System
(DFS-R), OS Windows Server 2008 R2 Enterprise provides a high accessibility for
critically important applications such as data base, exchanging messages
systems, file and print services.
1) Fault-tolerant clusters.
Windows Server 2008 R2 Enterprise supports fault-tolerant clusters which
are reliable, quick and simple in the setting and management. Servers
(components) which are included in the set of fault-tolerant clusters are
interacting constantly. If the component
becomes inaccessible (for example, in the case of fail or planned maintenance)
its functions are taken by another component. Users keep on working in the
usual mode. Fault-tolerant clusters in Windows
Server 2008 R2 Enterprise support up to 16 nodes and they have the following
advantages.
·
Dynamic transition
to a different resource in case of planned or unplanned maintenance.
·
Zooming by adding
new servers depending on the growth of requirements.
·
Geographically
arranged clusters which are less sensitive to a downtime.
- Server Core
High Accessibility includes the
preventing of downtime as well. While installing Windows
Server 2008 R2 Enterprise OS in minimal configuration (Server Core) it is possible
to delete secondary functions and drivers by the perspective of processing
load, and keep the subsystems which are need for the supporting server
roles. As a result, the server turns out
to be more safe and reliable and it is optimized for completion of high
capacity applications and services and needs less of the service and updating.
- Fault-tolerated Memory Synchronization.
This Windows
Server 2008 R2 Enterprise function allows the OS to copy the current Windows
sample to other operating system. Afterwards,
two identical memory samples function synchronously, providing a complete
fault-tolerance of the equipment (like a mirror reflection RAID 1 for hard
drives).
-
Distributed File System Replication
Windows Server 2008 R2
Enterprise Distributed File System Replication function checks the group of files
and replicates one data block in several files. Simultaneous replication of the
same files leads to a significant reduction of replication web traffic.
- Economically Effective Virtualization.
Correction management, effective
resource use, service costs and growth of the number of servers are important
for many companies. Virtualization technology helps to accomplish all tasks,
consolidate resources and reduce the costs of management and infrastructure
significantly as well.
Windows Server 2008
R2 Enterprise is a perfect platform for virtualization on the whole company
scale with the help of flexible and highly productive Hyper-V™ technology.
Microsoft Windows
Server 2008 R2 Enterprise license includes the right of using four extra virtual samples of Windows Server on the
same server with Windows Server 2008 R2 Enterprise
license. Economically effective
virtualization provides the following benefits to an organization:
·
Logical consolidation
of servers and management optimization.
·
Reduction of the
energy-saving, cooling and the rent of data processing center costs.
·
Control of the
growing number of services by using virtual machines for high accessibility
applications placing.
In addition, there is a
new function in Windows Server 2008 R2 Enterprise which is the dynamic migration. The function
improves the control of virtual machines sphere significantly. In the case of
planned or unplanned server failover, its virtual machines are always ready to
get another server.
Zooming increase.
The access to information is often made from heterogeneous spheres using
different systems and devices. Also it’s
necessary to increase the productivity at the same time with providing the
safety. IT-infrastructure has to keep its flexibility, management ability and
zooming, what is necessary for enlarged functionality, growing number of users
and employees support and protection, and improving the applications’ safety.
Windows Server 2008 R2 Enterprise has the power resource for satisfying
the growth of the demand on access to critically important applications. And it
allows to save and even increase the productivity in case of growth of number
of the mobile employees.
Windows Server 2008 R2 Enterprise’s advantages are listed below:
·
Supports up to 8 x64 sockets for processing peak
loads.
·
2 terabytes of Random
Access Memory for powerful application processing.
·
Support of unlimited number
of VNP-connections.
·
Authentication and
authorization of unlimited number of web access server connections and policy
web server.
·
Almost unlimited amount of
dial-up lock service connections.
Moreover, there is a function of hot memory addition in Windows Server 2008 R2
Enterprise, which allows you to install extra memory blocks on your computer
without reboot and make it accessible for OS and applications immediately.
