  • Over 1,000,000 downloads of XenServer
  • Customer types and usage150,000 unique companies of all sizesStrongest in NA and EMEA¼ Desktop; ½ Server; ¼ Cloud (public & private) On average 2,500 employees150 servers<30% virtual today; expect to get to >60%95% are satisfied or very satisfied and recommend the product to peers90% plan to expand their footprint in next year1/3rd plan to move to a premium edition
  • XenServer in 2012 InfoTech ‘Champions’ quadrant, and Gartner 2012 MQ ‘leaders quadrant’.It’s clear from the analysts report that XenServer is, and always has been, the Open Source Server Virtualization Leader. Citrix’s strategy for XenServer is to retain and strengthen this position, expanding XenServer’s footprint and functionality as a platform for server virtualization, desktop virtualization, networking and cloud.Key strengths that the analysts picked out:XenServer offers rich product capabilities for relatively low costVision of becoming “open” alternative for virtualization through to cloud computingCompatibility of XenServer with XenDesktop and other Citrix productsCitrix offers mature functionality for managing XenServerXenServer now has over 100,000 unique customers, and is still showing strong growth.
  • XenServer is designed to be simple, intuitive and easy to use. It can be installed and running in 10 minutes with only 4 megabytes of storage. It’s unique management architecture and console eliminates single points of failure so you can centrally manage hundreds of virtual servers.The free version of XenServer comes with enterprise class features including centralized management, disk snapshotting, and live virtual machine migration which enables organizations to manage their environment easily and intelligently while optimizing resources with zero-downtime to users. The premium editions of XenServer are conveniently priced per server and contain enhanced management and automation features such as high availability, dynamic memory control, workload balancing and distributed virtual network switch.Much simpler – "10 minutes to Xen"Far fewer "VMware Patch Tuesday" headachesDesigned to run on virtually any x86 hardwareOptimized for XenDesktop (e.g. IntelliCache)Equally matched to VMware in "green field" opportunities
  • XenServer is designed to address the virtualization needs of three critical markets.Within the Enterprise Data Center, XenServer solves the traditional server virtualization objectives of server consolidation, hardware independence while providing a high performance platform with a very straight forward management model.Since XenServer is a Citrix product, it only stands to reason that it can draw upon the vast experience Citrix has in optimizing the desktop experience and provide optimizations specific to desktop workloads.Lastly, with the emergence of mainstream cloud infrastructures, XenServer can draw upon the heritage of Amazon Web Services and Rackspace to provide a highly optimized platform for cloud deployments of any scale.
  • More and more organizations are choosing to host different workloads on different hypervisors enabling them not only better overall performance of their environment by also better utilizing their budget. Over 40% of companies in a recent Info-Tech study said they were using 2 or more server virtualization vendors within their datacenter, with almost half of these using Citrix and VMware together. The major challenge of this model is day to day management tasks, such as live migration, that you ideally want to complete through one management console. Currently both Citrix and Microsoft can manage each others VMs as well as VMware. VMware is beginning to offer management of Microsoft VMs.
  • Give examples of challenges – in most environments, there is little visibilityDifferent layers have different challengesMust look at all layers and find what is the root cause of the service problem?Network? VMware? AD? SQL? Storage? Profile Server?

    26. 26. Myth #1 “Virtualization MakesPerformance Management Easier”• Scope for performance management remains the same• 10 servers, 30 guests => 300 virtual machines to monitor• Higher complexity because of resource sharing across VMs• Guests share CPU, memory, disk, network resources• A single malfunctioning application in a guest can impactperformance of all other VMsPhysical Virtual
