Hi everyone, This is my very first post here and I'm asking because I cannot find the right answer to a problem we have. I have one customer who has a unique server running Linux + MySQL + Apache on the local disk but he wants to improve his systems because of the load (more than 3.000 users simultaneosly accessing the website). The thing is he has bought two servers (both identical) with 24GB RAM each and a local disk to install the OS (saying Debian) plus a storage appliance for centralized storage of the DBs. (this one: http://go.iomega.com/en-us/products.../px4-300r-sc/?partner=4760#tech_specsItem_tab) He basically needs a High Availability cluster for MySQL. How can this be done? I've read about using GFS but I'm not so sure how to make it work with an iSCSI device for HA. I attach a pic with the physical topology (sorry, only MSPAINT technology this time ) If you can help, I would appreciate it.
