中小企业桌面虚拟化方案：VDI-in-a-Box介绍

VDI-in-a-box是一个针对桌面虚拟化的整体打包方案，相关的支持服务器都以虚拟机的形式打包在一台服务器中。一台8核心、32GB内存、250GB存储的服务器可以支持30个主流规模的虚拟桌面，对SMB来说，应该是一个很有吸引力的桌面虚拟化解决方案

Citrix VDI-in-a-box 5安装在一台服务器上，包括Windows管理员交付虚拟桌面给使用任何设备的终端用户的所有工具。VDI-in-a-Box交付Citrix HDX获得高清晰桌面。也可以与Citrix Receiver软件客户端工作，得到VDI安全性与高可用×××。

增添了简化Windows管理员虚拟桌面管理的向导，并支持三大主要的hypervisor：Microsoft Hyper-V、Citrix XenServer与VMware vSphere、ESX和ESXi。

思杰也将Citrix VDI-in-a-Box与Citrix GoToManage结合，让IT能进行远程监控，并在多个地点支持虚拟桌面。

User DevicesVDI-in-a-Box provisioned desktops can be accessed from a Web browser, Citrix Receiver (formerly Citrix online plug-in), or the VDI-in-a-Box Java Desktop Client (using Java Runtime Environment (JRE) 1.6 or higher).

• Download Citrix Receiver from .
• Download JRE from .The following devices are supported:
• A computer running 32-bit or 64-bit Windows XP, Windows Vista, or Windows 7.
• A computer running the following 32-bit Linux operating systems:
• A computer running Mac OS X 10.5 or 10.6.
• A mobile device running any of the following operating systems:
• Thin clients running Windows XP Embedded or Linux operating systems.
• Thin clients running the latest version of Citrix Receiver.
• Supported certified thin clients include:

Secure Remote Connectivity

Secure remote connections from user devices to virtual desktops are supported for the following products:

• Citrix Access Gateway VPX 5.0
• Citrix Access Gateway 5.0

Virtual Desktop Operating Systems

• Windows XP Service Pack 3, Professional edition – 32-bit version
• Windows 7 Service Pack 1 Professional, Enterprise editions – 32-bit or 64-bit versions

Windows 7 N is not supported.

Windows Virtual Desktop Access Volume License is needed to access virtual desktops. Please refer to for licensing details.

System Resource Requirements

The following provides recommended CPU, memory, and disk allocations to use when sizing a VDI-in-a-Box deployment. These recommendations are based on an average task worker desktop and may vary based on your desktop needs.

• VDI-in-a-Box Manager appliance
• CPU Requirements
• Memory RequirementsMemory requirements per server is the sum of the memory required to run the virtual desktops on that server and the memory required by the VDI-in-a-Box Manager (vdiManager).Note: Ensure you have adequate RAM in the system. Lack of sufficient RAM results in extremely slow provisioning times for virtual desktops and poor response times for provisioned desktops.
• Disk size requirements (for Citrix XenServer with Thin Provisioning enabled and VMware ESXi)This is the sum of the disk space required to store desktop p_w_picpaths, to run the virtual desktops, and to use vdiManager.
• Disk size requirements (for Citrix XenServer without Thin Provisioning or with Thin Provisioning disabled)
• Disk size requirements for Microsoft Hyper-V
• Types of Disks

支持客户端协议及设备：

Protocols Supported by VDI-in-a-Box

1. HDX:

This is the default protocol.

No separate license is required.

HDX provides a high-definition user experience.

HDX provides better multimedia support while using less bandwidth.

HDX is suitable for remote access over a WAN.

2. Remote Desktop Connection (RDP) V6 and V7:

RDP is suitable for LAN deployments.

Accessing VDI-in-a-Box Virtual Desktops

Users access VDI-in-a-Box virtual desktops in any of three ways:

1. Web browser – Web browsers support both HDX and RDP, although some configuration is required to use each protocol.

2. Citrix Receiver (formerly Citrix online plug-in)

allows direct access to VDI-in-a-Box desktops through an HDX connection without the use of a Web browser or Java client.

Receiver connects to VDI-in-a-Box desktops on Windows, Mac, Linux, iOS, and Android platforms.

3. Zero-maintenance VDI-in-a-Box Java Client

The Java client automatically checks for updates and refreshes itself as needed.

The client requires Java Runtime Environment (JRE) 1.6 or higher.

The client switches to an RDP connection if an HDX connection is not available.

Comparing Client Access

Logging on From a User Device

The following figure shows a basic logon sequence between a Web browser on a user device and a server with VDI-in-a-Box Manager. An HDX session between the user device and a specific virtual desktop on the server is being created using Citrix Receiver. Once the connection is created, the session traffic takes place between Receiver and the virtual desktop only. The same sequence applies when the Java client is used.

With Citrix Receiver, older and low-end thin clients that do not have browsers can be used to access VDI-in-a-Box virtual desktops. Mobile devices, such as the iPad, can also be used with Receiver to access VDI-in-a-Box virtual desktops without requiring a Web browser or Java client.
