Server Virtualization:
In addition to reduced capital costs, the fewer physical servers and reduced data center complexity required by server virtualization can also reduce administrative costs. Virtualized server management tools can contribute to improved administrative productivity. With a small set of server management tools that are standardized across the enterprise, training costs can be reduced. Also, fewer servers can reduce the IT infrastructure footprint and associated utility costs for power and cooling.
Virtuozzo from SWsoft is server virtualization software that Application availability is essential to ongoing mission-makes very efficient use of hardware and operating system critical operations. Server virtualization helps keep business

Virtuozzo employs a technology known as OS operations running smoothly by providing the tools to migrate virtualization to define, configure, and operate multiple virtual a virtual machine to a different physical host with a service private servers (VPSs) in a single hardware node, as shown in interruption of only a few seconds-eliminating hours of Virtuozzo is available for Microsoft Windows Server 2003 and In the case of an equipment or application failure, a virtual multiple Linux distributions, and runs on platforms based on machine on another physical host can be provisioned and
Intel Pentium processors, 64-bit Intel Xeo- processors, and started in minutes. Backup data can be restored to the new Intel Itanium 2 processors. Virtuozzo server virtualization supports multiprocessor session quickly, minimizing downtime. configurations with up to 32 processors and 64 GB of memory. The result is increased application availability, as application
The server virtualization technique employed by Virtuozzo (see sidebar outages in a virtualized environment are reduced to minutes on page 3) uses a single, unmodified image of the OS to host all or hours instead of days.
Adapters offer exceptional throughput and some of the While a VPS can be created and started in minutes, any fastest Ethernet connectivity available. Both adapters feature migration or restoration operation requires time to transfer jumbo frame support of up to 16 KB, which reduces packet all of the data from the source to the target. Network overhead for increased performance. To reduce processor throughput is directly related to the time it takes to copy involvement with the processing of network traffic, each the data to a new VPS on a different hardware node.
Adapters or with LAN on Motherboard components to achieve time-consuming to fix. Providing an alternate network path the desired scalability. Throughput counts during a VPS through a meshed switch fabric and using multiport adapters restore operation; the faster data can be transferred to the that support failover can mitigate that risk and improve new VPS, the sooner the VPS can be placed in operation.
Benifits of Server Virtualization
At very high data rates, network traffic can take a toll on All of these considerations point to designing a virtualized server processor cycles. All Intel PRO/1000 Server Adapters infrastructure's networking subsystems with the capacity feature interrupt moderation, which significantly reduces and availability features delivered by multiple high-capacity processor utilization and makes more processor resources network connections. This can be challenging if servers are available to applications. peripheral component interconnect (PCI) slot-constrained.
While Virtuozzo provides comprehensive remote management ensure extensive compatibility with the latest server virtualization and capabilities for fine-grained VPS control, dual- and quad-networking environments. Intel adapters are compatible port Intel adapters support remote hardware management with full-height and low-profile PCI slots: the standard, full-standards to further reduce administrative costs.
