"The Majority Rules !"
In a nutshell, you have Quorum if you have the majority.
Quorum is the number of "operational" nodes in a cluster that are required to control the resources, modify the cluster definition, or perform certain cluster operations.
The main goals of quorum operations:
- identify who has the majority when a cluster is broken up into sub-clusters
- keep data consistent, especially when shared file systems are being used
- protect critical resources … maintain HA control

Proper maintenance of your Provisioning Server is necessary for smooth data center management operations. Without following basic guidelines for disk management and resource handling you can find yourself unable to perform necessary provisioning actions when the time comes. The key aspect for TPM datacenter performance is the database connection. We do most of our testing and performance baselines using IBM DB2 and as such most of our recommendations are made towards configuring the DB2 management server appropriately. A few key items to...

The Olympics always bring a strong sense of competition as countries vie for top honors, fueled with nationalism and pure athletic pride on the line. In every sport there is almost always one competitor out in front, willing to wear a target on her/his back, doing the extra training and utilizing his/her resources more effectively when the challenge arises. We admire their grace, strength and success. We desire their quality. Without launching into a philosophical discussion on quality, I do want to tie the above premise into an IT model:... [More]
