Avoiding downtime using Linux High Availability

LINBIT @ NAGIOS WORLD CONFERANCE

OCTOBER 13 – 16

Saint Paul, Minnesota



Presenting: “Avoiding Downtime Using Linux High Availability” is LINBIT’s Jeremy Rust

This broad presentation is designed to be accessible to a wide audience and provide a overview of High availability using DRBD and Nagios Software.

LINBIT and Nagios Enterprises have colaborated to build a Highly Available Nagios XI monitoring solution to be generaly available shortly.
 
Andy Brist of Nagios Enterprises,  will be giving a more technically advanced presentation called: "High Availability and Fail-over Solutions for Nagios XI".  This presentation will be based on the core LINBIT Linux HA technologies.   Andy's presentation will go more in depth and also provide an inside look at the interworkings of HA within Nagios XI.

LINBIT’s presentation will include:

1. Because: TIME IS MONEY (Downtime isn’t cheap)     
2. What is High Availability --- !=backup
3. What is “Distributed Replicated Block Device” — "network raid 1, Over 15 years of development"
4. Comparison of hardware vs software — hardware and appliance options compared to software’s flexible architecture.
5. Different means of copying data in real time -application, DB, filesystem, VM’s… pro’s / cons
6. The Linux HA Cluster – visuial diagram’s of clustering
7. Heartbeat - Corosync -- the communication layer
8. Pacemaker -- The all powerful Cluster Resource Manager
9. What is Disaster Recovery --Real time replication between physically separate sites.
10. DRBD in the cloud, under it, and along side it.
11. Q+A -- Free "I’m Highly Available" T-shirts

LINBIT Implements Open Source Virtualization for the Felder Group

LINBIT Implements Open Source Virtualization for the Felder Group

Felder, the international woodwork machinery specialists for the industrial, retail and private sectors, favors open source software for its IT services. LINBIT, Austria's largest Linux service provider, supported Felder in designing a virtualization solution based on Red Hat Enterprise Virtualization. Felder is very satisfied with the performance of the Red Hat based solution.

oVirt + DRBD: High available Virtualization at a most reasonable price

LINBIT deploys high available virtualization environments on only two servers

LINBIT deploys software that accomplishes high availability (HA) for virtualized environments; this can be accomplished with real-time replication of data across as few as two servers. The software that accomplishes this is DRBD, it is a adressed as a block device and allows for replication of data in realtime andLINBIT, the worldwide specialist in Linux HA has developed a solution where DRBD and oVirt are used on only two servers to create a complete HA virtualized enviroment. The combination of these Open Source projects is the simplest and most economical possibility for enterprises with several locations to operate virtual IT architectures with heavy demands. The solution can also be deployed with RHEV (Red Hat Enterprise Virtualization) and is suitable for both server and desktop uses.

DRBD Online Training Trailer

Brand New: Linbit Online Training

DRBD Training is one of LINBIT's core businesses. A vast number System Engineers earn their LINBIT Certified Engineer status every year. They know how to build clusters based on open source components. They know tuning them and they know how to run them in a productive environment.

What’s the result?

That's easy: less service downtime,more weekends and happier customers

Flying around the world is nice. To get trained from one of the pioneers in Linux clustering people fly to cities like Milan, Barcelona, Miami or Edinburgh.

But maybe you are not able to travel because travel expenses are killing your budget. Also taking 3 days off to focus on one thing and one thing only is often simply not possible. If you are from overseas you'd even lose a whole week.

That’s one of the reasons why we created an Online LCE Training permitting systems engineers to get the skills to deploy high availability Linux systems.

Watch the trailer below to see how it will look like:

 

Get more!

Saving travel expenses isn't the only benefit you are getting from Online Training.

Think about it, you're sitting in a classroom training and at some point you just lose focus and concentration. That's completely normal. You would need a break but the training doesn’t break when you need it.

With a video it is simple to stop and break whenever you want. Like a movie you will watch your favorite scenes over and over again and skip the parts you already know.

The LCE Online Training is perfect for you if you are chronically busy and not able to travel, you want to learn at your own rhythm and you want to attend LINBIT’s LCA Training.

What's covered?

The Online Training covers the whole Linux cluster stack.

  • DRBD configuration and troubleshooting
  • DRBD Performance Tuning
  • DRBD Internals
  • Pacemaker and Heartbeat Configuration
  • Pacemaker Troubleshooting

Stay tuned!
