1 Introduction Wyse Management Suite is the next generation management solution and enables you to configure, monitor, manage, and optimize your Dell Wyse thin clients. This helps you to deploy and manage thin clients on a high availability set-up with improved performance. It offers advanced feature options such as cloud versus on-premises deployment, manage-from-anywhere by using a mobile application, and enhanced security such as BIOS configuration and port lockdown.
2 High availability architecture The Dell Wyse Management Suite architecture consists of Windows Server 2012 R2/2016/2019 with failover cluster enabled. The Windows cluster contains a main computer that supports other applications and ensures minimum downtime by harnessing the redundant. This is used for application failover for Tomcat, Memcache, MQTT services. MongoDB database cluster helps in the event of primary database failure the secondary database will take over.
Table 1. System requirements Product Port Protocol Description Microsoft Windows Server 2012 R2/2016/2019 • • • • • Minimum disk space—40 GB Minimum number of systems—2 Minimum memory (RAM)—8 GB Minimum CPU requirements—4 Server where Wyse Management Suite is hosted. MySQL Cluster • Network communication port— TCP:3306 • • • • Minimum disk space—40 GB Minimum number of systems—3 Minimum memory (RAM)—8 GB Minimum CPU requirements—4 Server in the high availability setup.
3 High availability on Windows Server 2012 R2/2016/2019 A failover cluster is a group of independent systems that increases the availability and scalability of clustered roles. This feature supports multiple workloads running clusters on hardware or on virtual machines. A failover cluster is a group of systems that are independent and increases the availability and scalability of clustered roles. The clustered servers are the nodes that are connected to one another as a network.

7 Achieve high availability for Teradici devices Wyse Management Suite uses the HAProxy hosted on the Ubuntu server 16.04.1 LTS to perform load balancing between the EMSDK servers. HAProxy is a load balancer proxy that can also provide high availability based on how it is configured. It is a popular open source software for TCP/HTTP Load Balancer, and proxy solution which runs on Linux operating system.
The following text is a sample HAProxy configuration file: global log /dev/log local0 log /dev/log local1 notice chroot /var/lib/haproxy daemon #maxconn is maximum allowed connections maxconn 60000 defaults log global mode tcp timeout connect 5000ms timeout client 50000ms timeout server 50000ms errorfile 400 /etc/haproxy/errors/400.http errorfile 403 /etc/haproxy/errors/403.http errorfile 408 /etc/haproxy/errors/408.http errorfile 500 /etc/haproxy/errors/500.http errorfile 502 /etc/haproxy/errors/502.
8 Install Wyse Management Suite on Windows Server 2012 R2/2016/2019 Prerequisites Ensure that the following servers are configured before installation of Wyse Management Suite application: • • • • Windows Fail over Cluster on Two Nodes MongoDB Server Running with replica set MySQL Server InnoDB Cluster up running MySQL Router installed on the two Nodes About this task Installation of Wyse Management Suite 1.3 or higher on both the Nodes in Windows Cluster Steps 1.
Figure 64. Configuration 4. Select the External MariaDB option for MySQL. Provide MySQL router address (Local Host if it is installed on Wyse Management Suite server node) in the External Maria DB Server fields with the port number(Default 6446). You must type the MySQL database user account information that was created initially. NOTE: Ensure that the "Stratus" Database is created and "DB User" account(stratus) with appropriate Privileges is created on MySQL server.
Figure 66. Database command d. Execute following commands to create and Stratus User account and privileges: • Create user 'stratus'@'localhost' • Create user 'stratus'@'10.150.132.21' • Set password for 'stratus'@'localhost' = password ('PASSWORD') • Set password for 'stratus'@'IP ADDRESS'= password ('PASSWORD') • Grant all privileges on *.* to 'stratus'@'IP ADDRESS' identified by 'PASSWORD' with grant option. • Grant all privileges on *.
Figure 69. Configuration 6. Provide administrator credentials and email address information. Figure 70. Configuration 7. Provide Teradici EM SDK Port information and CIFS User Account information.
Figure 71. Teradici EM SDK 8. Provide ‘Destination Installation folder path’ and ‘Shared UNC path’ for Local repository. Figure 72. Destination 9. Recheck the Installation Summary information before we proceed with the Wyse Management Suite installation. 10. Complete the Installation on both the nodes. Type the Destination Installation folder path and Shared UNC path for the local repository and then click Next. The message The installation was successful is displayed.
After 'Data' folder is deleted from the shared UNC WMS Local Repository path, you can install Wyse Management Suite Application in the Node 2 of the Windows Cluster. Figure 73.
9 Post installation checks About this task Do the following to check the high availability for Wyse Management Suite: • • Launch the Wyse Management Suite administrator portal and check whether you can log in using the web interface. Edit the bootstrap.properties file in the Tomcat server under the \Dell\WMS\Tomcat-9\webapps\ccm-web\WEB-INF \classes folder for MongoDB as follows: mongodb.
10 Upgrade Wyse Management Suite version 1.3 to 1.4 Prerequisites • • Ensure that the mongodb.seedList value in the bootstrap.properties file includes backslash character (\) in the list of Mongo database servers. The bootstrap.properties file is at Tomcat-9\webapps\ccm-web\WEB-INF\classes, mongodb.seedList = MongoDBServer1_IP\:27017, MongoDBServer2_IP\:27017, MongoDBServer3_IP \:27017. Figure 74.
