Comparison: EMC PowerPath vs. GNU/Linux dm-multipath

While on the topic of Support cycles and End-of-Life (EOL) notices... EMC has given PowerPath 5.0.0 for Linux an EOL from May 31st, 2009. So I'm checking if we'll upgrade to PowerPath 5.1.x or switch over to a fresh Linux release and use dm-multipath (aka dm-mpio, native Linux multi-pathing.

blog'o thnet has a nice Comparison: EMC PowerPath vs. GNU/Linux dm-multipath for your convenience.

Preventing PuTTY timeouts

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.

Dell Linux - OMSA Hardware Monitoring

Just getting started using Dell's OpenManage Server Administrator (OMSA) on our Oracle Linux platform. There are some confusing instructions going around so it's not immediately clear what to do, hence my blogging here. :) There is a site on Dell - Hardware Monitoring , as well as a wiki with instruction on how to setup their OMSA tooling using yum or up2date. [update]My first update for their instructions: be sure your server has Internet access, as most servers will use a proxy or so. use export http_proxy=http://yourproxy.example.com:port to configure it just for the session, and setup up2date to use an HTTP proxy by editing the settings in /etc/sysconfig/rhn/up2date .
