Techniques in Advanced Server Load Balancing

Course Code:TRNG 0240
Course Duration: Three days

Schedule and Registration

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.

Course Contents

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
