TOPIC: Inline Dedupe & Compression for Linux Block Storage

PRESENTED BY: Louis Imershein,
Principal Product Manager for Data Reduction Technologies, Red Hat


Data deduplication and compression can increase the capacity of storage,
allowing users make more efficient use of existing storage, and to make
new fast storage more affordable.  Traditionally, these data-reduction
technologies have been available in proprietary storage systems, but
more recently they've made their way into open source, with projects
such as ZFS and btrfs, as well as with backup-specific applications such
as OpenDedupe (http://opendedup.org/).  Each of these has issues:  Either
they are resource hogs, or they are designed to address limited use
cases.  The Virtual Data Optimizer
(https://access.redhat.com/ecosystem/software/1484263) dm-vdo) is a new
open source project from Red Hat that provides inline data reduction for
primary storage to the Linux block-storage stack.  Its intended for use
in active virtualization and/or container workloads, with minimal impact
to performance and resources.  This talk will introduce dm-vdo, describe
how it works, and detail resource requirements & effectiveness for
different use cases and performance impact.

SVLUG is pleased to co-sponsor this presentation with Silicon Valley
Linux Technology Meetup
