Time&  Place: January 13, 2011, 7pm, at Red Hat HQ
Presenter: Alan Porter

In the Linux kernel, the "device mapper" serves as a generic
framework to map one block device onto another. It forms the foundation
of software RAID, Logical Volume Manager, and LUKS disk encryption.  In
this instructional presentation, the LUG's own Alan Porter will show how
to use these three device mapper facilities.

RAID can be used to provide high availability disks to a service that
  can not tolerate downtime.  Logical Volume Manager can be used to
allocate storage space as needed, without regard for where the data is
physically stored.  And finally, LUKS allows you to encrypt the data
that is stored on a physical disk.

Alan Porter is a long-time member of TriLUG, and he is currently
serving on the steering committee.  In other words, when he's not
talking about Linux, he tries to recruit others to talk about Linux!
