Split MySQL DB read/write for Drupal 5
Posted by Swampcritter on November 5, 2008 at 7:20pm
I am the back-end engineer/architect working on consolidating a number of production web sites using Drupal 5.11 with the Drupal Memcache API as a base along with the multi-site configuration.
Here's the architecture so far...
- 2-node load balancer front-end (2 Cisco ASA 5510s)
- 4-node web/app servers: RHEL 5 + GFS + Drupal Memcache API + Memcached (Quad Xeon, 8GB Ram each)
- 1-node MySQL 5.x database server with two other MySQL servers in hot stand-by mode (Quad Xeon, 16GB Ram each)
- EMC SAN Storage (1.5TB allocated)
