OVERVIEW
================================================================

The 18th ACM Workshop on Hot Topics in Storage and File Systems
(HotStorage '26) will take place in person in Prague, Czechia,
preceding the 32nd Symposium on Operating Systems Principles
(SOSP '26). The workshop is sponsored by ACM in cooperation
with USENIX, and its proceedings will appear in the ACM Digital
Library.

The HotStorage workshop provides a forum for cutting-edge
storage research, a place where academic researchers and
industry practitioners can discuss new opportunities and
challenges in storage technology. Submissions should propose
new research directions, explore non-traditional approaches,
or report on noteworthy or counterintuitive learnings and
experience in emerging areas. Submissions will be judged on
their originality, technical merit, topical relevance, and
the likelihood of leading to insightful discussions that will
influence future storage systems design and applications.

In keeping with the goals of the HotStorage workshop, the
review process will favor submissions that are forward-looking
and open-ended. If you are only a couple of months away from
submitting to FAST, NSDI, EuroSys, VLDB, OSDI, SOSP, ASPLOS,
SoCC, etc. you are probably already past the sweet spot for
HotStorage. If you have a forward-looking or unorthodox idea
or new research, and some evidence or early working system to
support your view, but still have open questions, please
consider bringing your work to HotStorage. The program
committee will also welcome position papers that solicit
discussion on controversial topics, introduce emerging methods
and paradigms, or call out for new research directions.


TOPICS OF INTEREST

Topics include, but are not limited to:

• Application- and workload-specific storage
