Chapter 14. Network Setup

14.7.3. Storage Network Topology Requirements

The secondary storage NFS export is mounted by the secondary storage VM. Secondary storage traffic goes over the management traffic network, even if there is a separate storage network. Primary storage traffic goes over the storage network, if available. If you choose to place secondary storage NFS servers on the storage network, you must make sure there is a route from the management traffic network to the storage network.

14.7.4. External Firewall Topology Requirements

When external firewall integration is in place, the public IP VLAN must still be trunked to the Hosts. This is required to support the Secondary Storage VM and Console Proxy VM.

14.7.5. Advanced Zone Topology Requirements

With Advanced Networking, separate subnets must be used for private and public networks.

14.7.6. XenServer Topology Requirements

The Management Servers communicate with XenServer hosts on ports 22 (ssh), 80 (HTTP), and 443 (HTTPs).

14.7.7. VMware Topology Requirements

•The Management Server and secondary storage VMs must be able to access vCenter and all ESXi hosts in the zone. To allow the necessary access through the firewall, keep port 443 open.

•The Management Servers communicate with VMware vCenter servers on port 443 (HTTPs).

•The Management Servers communicate with the System VMs on port 3922 (ssh) on the management traffic network.

14.7.8. KVM Topology Requirements

The Management Servers communicate with KVM hosts on port 22 (ssh).

14.8. Guest Network Usage Integration for Traffic Sentinel

To collect usage data for a guest network, CloudPlatform needs to pull the data from an external network statistics collector installed on the network. Metering statistics for guest networks are available through CloudPlatform’s integration with inMon Traffic Sentinel.

Traffic Sentinel is a network traffic usage data collection package. CloudPlatform can feed statistics from Traffic Sentinel into its own usage records, providing a basis for billing users of cloud infrastructure. Traffic Sentinel uses the traffic monitoring protocol σΦλοω®. Routers and switches generate sFlow records and provide them for collection by Traffic Sentinel, then CloudPlatform queries the Traffic Sentinel database to obtain this information

To construct the query, CloudPlatform determines what guest IPs were in use during the current query interval. This includes both newly assigned IPs and IPs that were assigned in a previous time period and continued to be in use. CloudPlatform queries Traffic Sentinel for network statistics that apply

to these IPs during the time period they remained allocated in CloudPlatform. The returned data is correlated with the customer account that owned each IP and the timestamps when IPs were assigned and released in order to create billable metering records in CloudPlatform. When the Usage Server runs, it collects this data.

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.
