BALUG meeting: Tu 2017-11-21:

Inline Dedupe & Compression for Linux Block Storage -
Louis Imershein (Red Hat[1])

Data deduplication[2] and compression[3] 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. Each of these has issues, either they
are resource hogs, or they are designed to address limited use cases.
The Virtual Data Optimizer (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 with introduce dm-vdo, describe
how it works, resource requirements, effectiveness for different use
cases and performance impact.

Louis Imershein is the Principal Product Manager for Data Reduction
technologies at Red Hat. Louis came to Red Hat with 11 years of product
management experience in the data reduction software developed by
Permabit Technology Corporation[4], a company that supplied
deduplication and compression technology to major storage
manufacturers. Red Hat acquired the assets of Permabit in August of

Meeting Details...

     The meetings are always free, but dinner is not (unless you are our
     guest speaker, in which case we also treat you to dinner).  For
     Henry's Hunan Restaurant, if folks are agreeable, we'll share and
     dine "family" style, and split up the costs, and typical cost per
     person including tax and tip (but not including beverages beyond
     complementary tea) would be in the $13.00 to $20.00 range, and
     commonly around $15.00 to $17.00.  Cash may be preferred to ease
     splitting up the check.  One can also specifically order the
     dish(es) one needs/prefers (e.g. for dietary considerations) - and
     we also commonly order some dish(es) that may meet various dietary
     considerations) (e.g. vegetarian, non-pork, ...).  Please arrive by
     7:00 P.M., we expect to order entrees at that time, and may order
     appetizer(s) and/or soup(s) anytime after 6:30 P.M.

BALUG lists migrations & DreamHost.com hosting exodus

Just a reminder, hopefully everyone's switched back to the canonical
(lists.balug.org) by now, as temp.balug.org will be going away in near

   o BALUG was fully migrated off of DreamHost.com hosting 2017-09-17.
   o lists.balug.org is again the canonical name for the lists,
     both for web (https://lists.balug.org/) and list email
   o The temporary transitional domain temp.balug.org does
     still temporarily persist for ease of transition, but it
     will be removed in the fairly near future (sometime on or after
     2017-11-30 but not later than 2017-12-16T13:47:00+0000).
   o Further details available on the other lists (most notably
     BALUG-Admin), and also the wiki pages mentioned/referenced thereupon.
