Dear Portland Ruby Brigade and Portland Pythoneers,
There's an upcoming talk at PLUG AT that I think some of you will be
interested in: "DRDB HA Clustering on Commodity HW". I've been using
DRDB for years on cloud, virtual and physical servers to provide
highly-available data services without the expense, hassle and
single-point-of-failure issues of a hardware SAN. I recommend learning
more about it.

> Using DRBD to Build High-Availability Clusters on Commodity Hardware
> Charlie Schluting of LINBIT will explain how DRBD works and how people
> currently use it, with enough information to get you started building
> your own clusters.
> DRBD stands for Distributed Replicated Block Device, and as the name
> implies, allows you to replicate block devices over TCP. DRBD is
> extremely flexible due to the fact it is a block device, and as such is
> used in a variety of situations. At the most basic level, you can
> replicate data between two servers to provide synchronously replicated
> storage redundancy for either failover or disaster recovery purposes. In
> active/active mode, you can also run GFS, OCFS2, or other clustered file
> Topics that will be covered:
> - How it works, history, and future exciting news regarding mainline
> kernel inclusion
> - How it is used: HA-iSCSI, HA-NFS, Virtualization, Apache, Samba, etc.
> - Cluster Resource Manager options and recommendations, and news about
> the confusing changes in the Linux-HA / Clusterlabs communities.
> And the majority of the time will be spent on:
> - Example cluster configuration: hardware setup, installation and
> configuration, and cluster manager integration.
> Come with questions!
