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 2017.

Meeting Details...
Cost/Dining: 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 future:
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 (@lists.balug.org) 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.
