High availability

If you have a highly available cluster running over a shared filesystem such as GFS or Lustre etc. You can virtualize your nodes so that when a node needs to come down for maintainence or whatever, you can simply migrate the "virtual" node to other hardware, possible one that already has an instance running. XEN domain migration is very fast, less than 100ms from what I understand. It becomes a lot easier to attain "Five 9's" of uptime or better.

less than 100ms downtime,

less than 100ms downtime, that's awesome, I've done it and its true, if you continuosly ping a domain and migrate it, you only lose one of them.

nice howto, thank you!

I have the same resolution, Displays fine.

ah, I should have tried more

Anonymous's picture

ah, I should have tried more browsers. It's a Konqueror problem, firefox and opera look fine.

Looks bad in Safari too

You guys should test your pages in a few browsers. It comes out super wide for me, very irritating.

Thanks for the article though.

Yeah, Safari and Konqueror both use about the same engine.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
