XenServer Installation Steps | Citrix Systems 4.2 manual

Chapter 8. Installing XenServer for CloudPlatform

8.2. XenServer Installation Steps

1.From https://www.citrix.com/English/ss/downloads/, download the appropriate version of XenServer for your CloudPlatform version (see Section 8.1, “System Requirements for XenServer Hosts”). Install it using the Citrix XenServer Installation Guide.

2.After installation, perform the following configuration steps, which are described in the next few sections:

Required	Optional

Section 8.3, “Configure XenServer dom0	Section 8.7, “Install CloudPlatform XenServer
Memory”	Support Package (CSP)”

Section 8.4, “Username and Password”	Set up SR if not using NFS, iSCSI, or local
	disk; see Section 8.8, “Primary Storage Setup
	for XenServer”

Section 8.5, “Time Synchronization”	Section 8.9, “iSCSI Multipath Setup for
	XenServer (Optional)”

Section 8.6, “Licensing”	Section 8.10, “Physical Networking Setup for
	XenServer”

8.3. Configure XenServer dom0 Memory

Configure the XenServer dom0 settings to allocate more memory to dom0. This can enable XenServer to handle larger numbers of virtual machines. We recommend 2940 MB of RAM for XenServer dom0. For instructions on how to do this, see http://support.citrix.com/article/CTX126531. The article refers to XenServer 5.6, but the same information applies to XenServer 6.0.

8.4. Username and Password

All XenServers in a cluster must have the same username and password as configured in CloudPlatform.

8.5. Time Synchronization

The host must be set to use NTP. All hosts in a pod must have the same time.

1.Install NTP.

#yum install ntp

2.Edit the NTP configuration file to point to your NTP server.

#vi /etc/ntp.conf

Add one or more server lines in this file with the names of the NTP servers you want to use. For example:

server 0.xenserver.pool.ntp.org

server 1.xenserver.pool.ntp.org

server 2.xenserver.pool.ntp.org

server 3.xenserver.pool.ntp.org

4.2 specifications

Citrix Systems, a leading provider of virtualization solutions and cloud computing technologies, released version 4.2 of its popular software, Citrix XenApp, which was previously known as Presentation Server. This version marked a significant evolution in providing users with remote access to applications and desktops, emphasizing simplicity, performance, and security.

One of the standout features of Citrix XenApp 4.2 is its improved application streaming capabilities. This technology allows applications to be delivered to users in real-time, reducing the need for extensive local installations and enhancing the user experience. With application streaming, administrators can efficiently manage applications on a central server while ensuring that users have immediate access to the necessary tools.

Another highlight of this version is the enhanced security measures put in place to protect sensitive data. Citrix XenApp 4.2 includes support for SSL encryption, providing a secure communication channel for data transmitted between the server and clients. This is particularly crucial for businesses that need to comply with strict data protection regulations. Additionally, the integration of endpoint security features ensures that unauthorized access to applications is minimized.

Performance enhancements are also a critical focus in this release. Citrix optimized the delivery of applications over various network conditions, ensuring that users experience minimal latency regardless of their location. This was achieved through the incorporation of SmartAccess and SmartControl technologies, which allow administrators to set policies based on user roles, device types, and network conditions. This level of granularity enables organization-wide security without compromising on usability.

The user experience was further improved with a revamped interface, making it easier for end-users to access their applications and data. Simplified menus, clear navigation paths, and the ability to customize user settings contributed to a more efficient workflow, allowing users to focus on their tasks rather than struggling with the software.

Finally, Citrix XenApp 4.2 was designed to be highly scalable. Organizations of all sizes could deploy this solution to deliver applications efficiently, adapting to their specific needs as their user base grows or changes. This flexibility is crucial for businesses looking to future-proof their IT investments while maintaining optimal performance.

In summary, Citrix XenApp 4.2 stands out with its enhanced application streaming, robust security features, improved performance under varying conditions, user-friendly interface, and scalability, making it an ideal choice for organizations seeking to leverage virtualization for remote access to applications and desktops.
