I've been diving a bit into the RAM configuration of our new R710 Dell servers. They have new memory configuration settings. "Memory Optimized" mode can yield a 50% performance improvement at no cost other than to place DIMMs in appropriate slots. Dell has a white paper detailing the options a bit more: Optimizing DDR3 Memory Settings in New 11th-Generation Dell PowerEdge Servers. It also lists trade-offs of choosing one configuration over the other or when to go for a balanced intermediate.
Just found a great tip to prevent timeouts of PuTTY sessions. I'm fine with timeouts by the host, but in our case the firewall kills sessions after 30 minutes of inactivity... When using PuTTY to ssh to your Linux/Unix servers, be sure to use the feature to send NULL packets to prevent a timeout. I've set it to once every 900 seconds, i.e. 15 minutes... See screenshot on the right.
