HP SuperStack 3 Load Balancer Appliance 60

60CHAPTER 7: CONFIGURING CACHE REDIRECTION

■TCP Port — Server Load Balancer periodically attempts to establish a connection with each server using the same protocol (TCP or UDP) and port number as the server load balancing service uses. If any connection attempt fails, the server is marked as down and is removed from the pool of available servers for the service.

■None — No health checking is performed. All Servers are assumed to be operational.

9The Cache Profile Configuration - Health Checks page appears. This page supplies default settings, which can be modified for your network, for the following fields:

■Period

This sets the number of seconds that elapse between health checks.

■Retries field

This sets the number of retries a health check is attempted.

■Timeout

This sets the number of seconds the Server Load Balancer waits for a reply before the health check is timed out.

10Click Next.

11Click Finish.Your cache profile has been created.
