Techniques in Advanced Server Load Balancing (TRNG-0240)

Prerequisites

To fully benefit from this course you should attended the Basic Switch/Router Configuration and Management (TRNG-0103) and the Introduction to Web Switching and Load Balancing (TRNG-0202). It is also recommended that you have previous exposure to general network management issues in a Foundry Networks environment. A working knowledge of Foundry Networks' CLI is a must.

We strongly recommend that students bring their own PC to act as the console during labs. Recommended personal hardware includes:

  • Laptop Personal Computer with W2000 or higher
  • Ethernet NIC card
  • CD Drive
  • Serial Interface (DB-9 Connector)
  • Netscape 6.1 or better or Internet Explorer 5.5 or better

Course Content

The TRNG-0240 course is an in-depth study of server load balancing using Foundry Networks’ ServerIron products. The course focuses in on advanced techniques of implementing Server Load Balancing (SLB) in a variety of network topologies. It includes an intense study of SLB theory of operations, configuration, network design and troubleshooting. The course is labs (hands-on) intensive and as result is fast moving. Key topics include but are not limited to; Load Balancing, Global Server Load Balancing, Transparent Cache Switching and Layer 7 switching.

Course Objectives

After completing this course, the student will be able to:

  • Identify key SLB techniques available using the Foundry Networks ServerIron
  • Implement advanced designs and configurations in Server Load Balancing
  • Implement advanced SLB, Health Checks and Layer 7 switching features on the Foundry ServerIron products
  • Tune the Foundry Networks SLB implementation for fast Active-Active failover
  • Determine the appropriate SLB design for a given network requirement
  • Interconnect Foundry L2/L3 Switch Routers with the Foundry L4-7 SeverIron based on a network design
  • Troubleshoot the in class design implementations using the CLI show commands
