Server Virtualization
Virtualization can dramatically improve the efficiency and availability of resources and applications in your organization. Under the old, "one server – one application" paradigm, internal resources are often vastly underutilized and IT admins spend too much time managing servers and not on innovation.
Server virtualization enables one physical server to support multiple workloads in simultaneously running virtual machines. The workload – consisting of an operating system, application set and configuration – is decoupled from the physical computing platform by means of a virtual machine. This achieves some important things, such as isolation (running multiple workloads safely and securely on a single computing platform) and workload portability (moving the workload across different physical computing platforms). It is even possible with more advanced server virtualization platforms to migrate actively running workloads across physical servers. This allows the workload to float across a pool of physical computing resources, enabling IT departments to maximize available computing resources, reduce costs and deliver applications to users reliably and effectively.
Illumant has partnered with Citrix to provide XenServer, among the best performing and easiest to manage server virtualization solution
Citrix® XenServerTM
Citrix® XenServerTM is a server virtualization system that makes datacenters more agile and efficient through faster application delivery, higher levels of availability and improved utilization of IT resources. XenServer delivers the advanced features required by mission critical workloads (operating systems, applications and configurations) without sacrificing the ease-of-use necessary for wide-scale deployments. And XenServer's unique streaming technology can rapidly deliver workloads across virtual or physical servers making it the ideal virtualization platform for every server in the enterprise.
Optimize server and storage infrastructure
With Citrix XenServer, businesses can make more efficient use of server and storage resources. XenServer can run more virtual machines on a single physical server thanks to its powerful open source Xen hypervisor, efficient CPU and memory management, and hardware assisted I/O virtualization. XenServer's performance monitoring coupled with live migration and unique workload provisioning technology helps organizations balance computing resources across multiple servers for enterprise-wide optimization. These capabilities along with improved storage utilization from XenServer's dynamic workload provisioning allow organizations to achieve dramatic savings in IT administration, equipment, space, power and cooling.
Accelerate the delivery of server workloads
Citrix XenServer accelerates the delivery of applications through tools for provisioning server workloads. XenServer allows multiple servers to boot and run from a single shared image by dynamically provisioning server workloads to both virtual and physical servers. Dynamic workload provisioning eliminates storage normally required for individual server workload images, speeds the time to deliver applications and reduces the administrative burden of patching and upgrading multiple servers. XenServer also includes virtual machine provisioning templates, live migration and virtual machine auto placement allowing administrators to easily deploy and manage virtual server workloads for faster IT delivery.
Simplify the management of virtual infrastructure
XenServer includes powerful tools for managing virtual servers and virtual storage infrastructure. A simple, scalable management architecture allows XenServer users to group physical servers and storage resources into pools wherein users can easily provision, search, monitor, migrate and even protect virtual machines with automated high availability. XenServer also enables flexible, yet simple storage management of virtual machines by plugging directly into array-based storage services such as thin provisioning, snapshots, replication and deduplication.
