Cisco has published a paper titled: “Reference Architecture for 500-Seat and 1000-Seat Virtual Desktop Infrastructure, Citrix XenDesktop 7 built on Cisco UCS B200-M3 Blade Servers with EMC VNXe and Microsoft Hyper-V 2012“. The paper which contains 418 pages contains a reference architecture for building a VDI infrastructure which is validated by Cisco, Citrix, EMC and Microsoft.
The paper describes provides the architecture and design of a virtual desktop infrastructure that can grow from 500 users to 1000 users. The infrastructure is 100% virtualized on Microsoft Hyper-V Server 2012 with third- generation Cisco UCS B-Series B200 M3 Blade Servers iSCSI booting from an EMC VNXe3300 storage array. The virtual desktops are powered using Citrix Provisioning Server 7 and Citrix XenDesktop 7, with a mix of hosted shared desktops (70%) and pooled desktops (30%) to support the user population. Where applicable, the document provides best practice recommendations and sizing guidelines for customer deployments of XenDesktop 7 on the Cisco Unified Computing System.
The paper covers the following sections:
- Solution Component Benefits
- Summary of Main Findings
- Infrastructure components
- Solution Architecture
- Desktop Delivery Infrastructure – Citrix
- Test Setup and Configurations
- Login VSI Test Result
- Scalability Considerations and Guidelines
- Other Considerations
Citrix has announced version 5.4 of its all-in-one VDI (Virtual Desktop Infrastructure) soultion VDI-in-a-Box. this is by far the simplest way I have found to quickly setup and trial VDI and is very well aligned to the SMB/SME market
The major features introduced, leveraging the same technology of XenDesktop 7.1, are the support for Windows Server 2012 R2 Hyper-V and VMware ESXi 5.5 (and related vSphere implementations) in addition to Windows 8.1 as virtual desktop guest OS. The Citrix blog post explains all you need to know.
The Xen Project, the community which develops the Xen hypervisor under the GNU General Public License (GPLv2) and which is now transferred from Citrix to the Linux Foundation , today announced the release of version 4.3.1 of the Xen hypervisor. This so called Point release is the follow up of version 4.3 which was released in July this year.
Besides fixing some vulnerabilities, this release also introduces around 80 bug fixes and improvements, like adjustments to XSAVE management and bug fixes for nested virtualization, other low level system state handling and libxl tool stack.

Citrix today released a technical preview available for download of version 7.1 of its Virtual Desktop Infrastructure (VDI) product XenDesktop. You’ll need to have a Subscription Advantage in order to download the Technical Preview. The final version once released will mainly support the Microsoft Windows 8.1 and Windows Server 2012 R2 Operating Systems which will be generally available later this month.
Version 7.1 provides the following new features:
- Delivering virtual desktops and applications from Windows 8.1 and Windows Server 2012R2.
- Hyper-V 3 with local storage support when using Machine Creation Services (MCS)
- Flash redirection with Windows 8.1, Windows 8, Windows Server 2012 R2 and 2012
Besides releasing a tech preview of XenDesktop 7.1 Citrix also released a tech preview of XenServer hardware GPU sharing using NVIDIA GRID technology. In order for customers to review this vGPU technology they need compatible hardware, XenServer 6.2 and the Technical Preview of XenDesktop 7.1. Keep in mind that the preview of vGPU is designed for Windows 7 and Windows Server 2008 R2 workloads only.
