Complete, cost-effective datacenter and server virtualization
Citrix XenServer is a complete, managed server virtualization platform built on the powerful Xen hypervisor. Xen technology is widely acknowledged as the fastest and most secure virtualization software in the industry. XenServer is designed for efficient management of Windows® and Linux® virtual servers and delivers cost-effective server consolidation and business continuity.
What is server virtualization?
Server virtualization is a proven technology that enables multiple virtual machines to run on a single physical server. Each virtual machine is completely isolated from other virtual machines and is decoupled from the underlying host by a thin layer of software known as a hypervisor. This allows each virtual machine to run different operating systems and applications. Because the machines have been decoupled from the underlying host, the guest can also be moved from one physical server host to another while running; this is known as live migration. These attributes are transforming how organizations approach virtual computing.
The best choice for server virtualization and datacenter automation
XenServer is the enterprise-ready, cloud-proven virtualization platform that contains all the capabilities required to create and manage a virtual infrastructure. It is trusted by demanding organizations to run the most mission critical applications and used by the largest clouds.
- Cuts costs. By reducing the number of physical servers required in the datacenter, organizations are able to save on their power and cooling costs.
- Increases IT agility and efficiency. Customers can easily adapt to changing datacenter and computing needs by dynamically flexing capacity, optimizing VM placement, and automating repetitive management tasks.
- Improves performance and user productivity. By enabling 'zero downtime' maintenance, automatically recovering from hardware failure, and providing failover capabilities in disaster situations, end users are ensured access to mission critical application in all scenarios.
The free edition of XenServer starts with a 64-bit hypervisor and centralized management, live migration, and conversion tools to create a virtual platform that maximizes guest density and performance. The premium editions of XenServer extend the platform to enable organizations of any size to integrate and automate management processes, delivering a virtual datacenter solution.
How XenServer helps business?
Streamline datacenter operations through automation
By consolidating server workloads, XenServer reduces power, cooling and management costs and helps you make optimized use of existing hardware—but shrinking your overall number of servers is only one of the benefits of XenServer. Administrators can also automate key IT processes to improve application service delivery, saving both time and money. Improved IT reliability and the ability to adapt to ever-changing IT environments help you deliver optimal support to the business.
Adapt to increasing IT demands for administrative efficiency
Virtualization gives you the flexibility to adapt your datacenter to meet constantly evolving IT requirements. For example, XenServer optimizes the location of server workloads to improve performance and utilization while increasing server readiness within resource pools. This ensures that application requirements and expected performance levels are always met and helps you deliver new applications into production more quickly.
Reduce unplanned downtime
Natural disasters and other business disruptions can cripple any organization—but downtime and data loss are not acceptable in today's business environment. To keep the business moving and protect the bottom line, companies must protect their IT and data investments and keep the infrastructure running so users always have access to the IT resources their work depends on. With server virtualization, servers are separated from underlying hardware and delivered as virtual machines (VM), making the protection of VMs and associated data easier than in a physical infrastructure. This makes server virtualization a key strategy to protect IT infrastructure against natural disasters and business disruptions, helping organizations reduce downtime due to disasters and increase worker productivity.
Leverage the cloud
Now more than ever, enterprises are moving to cloud computing to lower capital costs and deliver more responsive and timely IT services to the business. With the growth of both public and private clouds, IT is rapidly expanding beyond traditional datacenter boundaries and exposing new concepts such as platform as a service (PaaS) or infrastructure as a service (IaaS) to users via an enterprise network. Inherent in the promise of cloud computing is an IT infrastructure that is extremely flexible and can be quickly customized to the meet needs of the business, rather than having the business bend to the needs of IT.
