IBM and Red Hat Solaris Migration CenterThis Week's Tech ChallengePlanning a migration to Linux from Solaris? Think you know Linux? Take the challenge. Each week we'll offer a new set of questions--designed for difficulty and prepared by Red Hat support technician Alex Bruno. Send your answer via email to [EMAIL PROTECTED] week's first correct response will receive cool Red Hat gear. Check back each Monday for a new challenge and a new prize. We'll post the week's winner and their correct response on the following Friday. Good luck. The ScenarioThe only thing that is constant is change. Although the statement is rather glib, it is also fortunate: as you have been promoted to replace the previous network administrator. This is an exciting point in your life: a new job, a new city, and a new relationship (not to drop names, but your new interest has the initials NFS.) The departure of your predecessor was very abrupt and the network setup they left behind was rather unorthodox. The first order of business is to get the network properly configured as your http server is being overwhelmed with requests. Your Tux static content server is connected to your static php, cgi-script disk, assume that the disk is high-availability, and is also connected to a http server and a https server. The problem is that the http server is being overwhelmed while the load on the https box is nominal. Both the http server and the https server are connected to tomcat servers which are accessing a db2 storage array. [Click here for a graphical representation of the current configuration. Numbers provided are relative measurements of load stress. In regards to my drawing abilities...I know...I know] The tech challenge is:Assume that you are allowed to re-purpose the existing Tux machine and add four additional servers. A Cisco router is available to port forward https and http traffic to different machines. However, it can not do load balancing on its own. How would you distribute the http load using Red Hat solutions (i.e. no third party software)?
