Server Virtualization and Desktop Virtualization

 

Server Virtualization

 

Citrix XenServer

XenServer as an open and powerful server virtualization platform, transfers the static and complex datacenter into a dynamic and easy-delivered management center, thereby largely lower the cost of ownership for desktop, cloud and server virtualization infrastructures.

 

 

 Dymanic Data Center

Citrix XenServer is a most effective way to achieve server virtualization and deliver dynamic data center, which will provide a flexible resource pool for computing and storage. Citrix XenServer extends the development and testing resources of the Xen virtualization engine, provides a simple-to-use dynamic virtualization solution. It also provides a comprehensive server virtualization capabilities with unparalleled scalability and high cost performance.

 

Consolidate Server, Lower Cost

With XenServer, you can deploy multiple virtual servers on shared hardware in order to improve utilization, reduce costs on procurement, power consumption, cooling systems and occupied space. Since the workloads of server can be instantly assigned to any available local system or a remote system, server virtualization can also reduce disaster recovery cost.

Make full use of innovative technology of Xen

XenServer’s creation is based upon Xen hypervisor. As the heart of XenServer, Xen hypervisor reduces the overhead cost and enhance the performance. XenServer platform takes full advantage of Intel VT and AMD Virtualization (AMD-V) platform for hardware-assisted virtualization, provides a faster, more efficient virtualization computing capability. Different from other virtualization products that built on closed-end proprietary systems, XenServer's open API allows users to access and control advanced functions through the existing server and storage hardware.

Citrix XenServer integrates Xen technology’s high performance, security, openness; easy management and simplified deployment together. Thereby, it is a perfect solution for rapid deployment of server, server consolidation, network development and test, and disaster recovery.

 

Powerful, high flexibility 

Citrix XenServer is a 64-bit virtualization platform, it provides scalability required by Microsoft Exchange Server、Microsoft SQL Server and other business-critical applications. A high-capacity in CPU and memory resources, the fine control on network and disk enable XenServer to provide the best quality of service (Qos). Running virtual machines can be migrated to the new server without causing a service interruption, it can also automatically assign basic workloads, and supports zero downtime. The open command-line interface (CLI) and programming interface enable the easy integration of XenServer with existing processes and management tools.

 

VMWare vSphere

 

Calculation

With powerful features and high performance of virtualization layer, vSphere ESXi can process the server hardware resources abstractedly, and allow the resource share among multiple virtual machines.

 

Distributed Resources Scheduler (DRS) adjusts computing resources according to business priorities through automatic load balancing across the hosts. It also reduces the energy consumption during the low load off period.

vMotion lively migrates the virtual machines among hosts, clusters, distributed switch and vCenter Server remotely (RTT up to 100 ms), avoids the force running of the application by the planned server maintenance.

 

Management and Operations

Consistent Management maximizes the benefits of your virtual data center with unified easy-to-use operations management. Intelligent operation easily identify configuration errors, resource starvation and performance issues with deep visibility into virtual and physical storage infrastructure topology. Operation automation increase resource utilization through automated capacity optimization and planning. vCenter Server achieves the centralized management on vSphere platform. vRealize Orchestrator provides a simple drag and drop interface to set up your workflow.

 

 

 Network 

Network I/O Control lets you set up rules and policies for each virtual machine to ensure business-critical applications get priority network access.

Distributed Switch (VDS) simplifies virtual machine networking by letting you set up virtual machine access switching for your entire data center from a centralized interface. This makes it easy to provision, administer and monitor virtual networking across multiple hosts and clusters.

 

Automation

By automating routine tasks, VMware vSphere provides accurate, consistent and repeatable solutions that save IT administrators time and effort. Automation is integrated into all aspects of the vSphere platform.

Auto Deploy: automate new host provisioning with no manual intervention, allowing for rapid deployment of large numbers of vSphere hosts.

Support ongoing host administration by capturing host-level configuration settings and saving them as a template to configure other vSphere hosts.

Update Manager reduces time spent on routine remediation by automating the tracking, patching and updating of your vSphere hosts, as well as applications and operating systems.

 

 Storage

VMware vSphere storage virtualization is a combination of vSphere features and APIs that provide an abstraction layer for physical storage resources to be addressed, managed and optimized in a virtualization deployment.

 

Storage Distributed Resources Scheduler (DRS) provides intelligent virtual machine placement and load balancing mechanisms based on I/O latency and storage capacity.

Reduces the number of storage resource selection steps by grouping storage according to user-defined policies.

Storage vMotion performs proactive, non-disruptive storage migrations, eliminating virtual machine storage I/O bottle necks and freeing up valuable storage capacity.

Storage I/O Control prioritizes storage access by continuously monitoring the I/O load of a storage volume and dynamically allocating available I/O resources to virtual machines according to business needs.

VMFS allows multiple vSphere hosts to read and write to the same storage concurrently and supports all common storage interconnects for block-based storage (DASD, Fibre Channel, FCoE, iSCSI and NAS).

Storage Thin Provisioning increases virtual machine storage utilization by enabling dynamic allocation and intelligent provisioning of physical storage capacity.

Storage API enhances your storage awareness, data protection and array integration and takes advantage of multi-pathing capabilities offered by third-party storage vendors.
