We generally meet monthly in San Francisco (in/near SOMA/Chinatown area, near downtown). We also operate several mailing lists.
BALUG generally meets the third Tuesday of each month. We talk about Linux and related topics, and we typically share ample portions of food (e.g. Chinese).
We typically have a speaker/presentation for our meetings (generally starting around the tail end of dinner or immediately following dinner). In any case, with or without a speaker/presentation arranged and scheduled, our meetings include good people, and interesting conversations. And if we haven't announced/posted a speaker/presentation, don't let that fool you - sometimes we manage to score an excellent speaker/presentation (e.g. at the last minute) without our having managed to get it posted onto the web site and an announcement sent out in advance.
Please RSVP if you're planning to attend.
Meeting kicks off at 6:30 P.M. - we start with meet and greet and chat and such, then proceed with dining around 7:00 P.M. for dinner - please arrive before 7:00 P.M. if you want to join us for dinner.
Please RSVP if you're planning to attend.
To do so please e-mail us a note at
indicating meeting date. If you'll be bringing additional guest(s) please let us know total number of folks you're RSVPing for.
Also please let us know any special requirements or concerns you may have (e.g. if you have any particular dietary considerations, so that we might possibly be able to accommodate you, or if you won't be dining with us but do wish to otherwise join our meeting).
dinner costs? May vary - see venue for more information (we may dine and share "family" style and split up the costs, if folks are agreeable to that - for Henry's Hunan Restaurant, 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, ...)).
Inline Dedupe & Compression for Linux Block Storage- Louis Imershein (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. 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, a company that supplied deduplication and compression technology to major storage manufacturers. Red Hat acquired the assets of Permabit in August of 2017.
