                                PRESENTATION

                         DRBD and Pacemaker part II

                                     by

                               Adam Gandelman
                               www.linbit.com

DRBD stands for Distributed Replicated Block Device.  Mainline since
2.6.33, it is used to replicate data at the block level over the network
in a "network RAID1" fashion.   It is generally deployed as a cost
effective, shared-nothing alternative to a SAN and used as the building
block for high availability clusters. Pacemaker is currently the de
facto open-source cluster resource manager (CRM) for Linux HA
clustering.   With it, nodes and services can be monitored and managed
to ensure maximum uptime in the face of the most severe service and
hardware level failures.  Combining the two allows admins to %99.999
uptime at a fraction of the price of proprietary alternatives.

In LINBIT's second PLUG Advance Topics installment, Adam Gandelman will
give a more in-depth view of DRBD and Pacemaker and demonstrate how they
work closely together to keep applications running and consistent.
During the second half of the presentation, Adam will provide attendees
with a real-world example by configuring a highly-available LAMP cluster
from the ground up. Though geared toward web services, the concepts
presented can easily be expanded to provide the HA gaurantee to
virtually any Linux service.

Agenda: - Brief re-introduction to DRBD, Pacemaker and HA clustering
concepts. - Overview of various use cases and interesting deployments -
Configuration and implementation of a highly-available LAMP cluster
using DRBD for data redundancy and Pacemaker for resource management.

Adam Gandelman is an expert in open-source clustering and high
availability. Originally from New England, Adam lives in Portland, OR
where he has been working at LINBIT, developers of DRBD and maintainers
of Heartbeat. Aside from providing top-level Linux High-Availability and
Disaster Recovery consulting for customers in the Americas, he leads
LINBIT training courses in the US, doubles as a technical writer and
regularly contributes to related open-source projects.

                    A projector has been arranged!
