Call for Papers
ACM HotStorage ’23

The 15th ACM Workshop on Hot Topics in Storage and File Systems (HotStorage
ʼ23), will take place in person on Sunday, July 9th, 2023 in Boston, MA a day
before the 17th USENIX Symposium on Operating Systems Design and Implementation
(OSDI ʼ23) and the 2023 USENIX Annual Technical Conference (ATC ʼ23). The
workshop is sponsored by ACM, runs in cooperation with USENIX, and its
proceedings will appear in the ACM Digital Library.

Important Dates
* Paper submissions due: Thursday, March 30, 2023, AoE
* Notification to authors: Friday, May 19, 2023, AoE
* Final papers due: Thursday, June 8, 2023, AoE

In 2023 the workshop will return to in-person format after a few years of being
virtual because of COVID-19 pandemic. It will be hosted at Boston University in
Boston, Massachusetts. The location and date of the workshop - just a day before
17th USENIX Symposium on Operating Systems Design and Implementation (OSDI ’23)
and the 2023 USENIX Annual Technical Conference (ATC ʼ23) - were selected to
promote submissions and attendance of the workshop.

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
HotStorage '23 welcomes innovative submissions in the broad areas of storage,
data management, data applications, and cross-disciplinary topics that relate to
these. Some specific areas are listed below but the list is not exhaustive:
* Application- and workload-specific storage
* Archival and backup storage
* Caching, tiering, and replication
* Cloud storage
* Disaggregated and distributed storage
* Energy-efficient storage
* File systems
* Flash/SSD
* Key-value and NoSQL stores
* Memory-centric storage systems
* Mobile and edge device (sensors, home, and IoT, etc.) storage
* New storage hardware, DPUs, persistent memory
* Next generation storage (DNA, glass)
* Performance modeling and prediction for storage
* Programming models and compilers for storage
* Quality of service for storage
* Security and privacy of storage
* Storage reliability, erasure coding
* Storage systems for ML and applying ML to storage systems

What to Expect from the Workshop
HotStorage’23 will be a one-day in-person workshop with presentations of each
paper followed by a discussion. At least one author of each accepted paper must
attend the workshop to participate in discussions and answer questions; if you
have any questions or concerns about attending the workshop as a presenting
author, please contact the program co-chairs via to
discuss. Presentation details and guidelines will be communicated to the authors
of the accepted papers.

Submission Instructions
Submissions must be no longer than five (5) two-column pages excluding
references and appendices and should be submitted electronically via the
submission form at

Indicating Paper Type. Authors should indicate one of two paper types in both
the submission and on HotCRP: Position or Regular. Paper titles should be
prefixed by their type in the submission. For example, “Position: XYZ”. Position
titles should explicitly state and argue for a position; the more interesting or
forward-looking the position, the better the paper is a match for HotStorage.
Position papers may also be used to put forward a vision for storage systems.
Regular papers might contain a new and interesting result that is at an early
stage and not yet ready for a conference submission.

Papers should be submitted electronically as a PDF. All text and figures must
fit within a 7”x9” text block, centered on the page, using two columns with .33
inches of separation. The paper should be typeset using a 10-point font (Times
New Roman or similar) with a 12-point (single-spaced) leading.

Please follow paper formatting instructions. The author kit, which contains the
Latex style and template, is available here. Please ensure that your paper
satisfies all the above requirements for content and formatting before
submission; if you have a question about any of these issues, please email the
program chairs

Additional instructions regarding camera-ready versions of accepted papers will
be sent directly to the corresponding authors and will appear online closer to
the deadline.

Submissions to HotStorage ʼ23 may not be under consideration for any other
venue. Simultaneous submission of the same work to multiple venues, submission
of previously published work, or plagiarism constitutes dishonesty or fraud.
HotStorage, like other scientific and technical conferences and journals,
prohibits these practices and may take action against authors who have committed
them. We are following the ACM Prior Publication and Simultaneous Submissions
Policy. Questions? Contact the program chairs.

The review process is double-blind. Authors must not be identified in the
submissions, either explicitly or by implication. When it is necessary to cite
your own work, cite it as if it were written by a third party. Do not say
"reference removed for blind review." Papers from industry may identify the
company or the product. For example, it is acceptable to talk about Company X's
Product Y (X and Y need not be blinded). Papers accompanied by nondisclosure
agreement forms will not be considered. Accepted submissions will be treated as
confidential prior to publication on the HotStorage ʼ23 website; rejected
submissions will be permanently treated as confidential.

All papers will be available online to registered attendees before the workshop.
If your accepted paper should not be published prior to the event, please notify
the chairs. The papers will be available online to everyone beginning on the
first day of the workshop.

A paper submitted to HotStorage can be submitted simultaneously to Arxiv, with
some changes. We would like the authors to make an honest effort to preserve
anonymity. Please ensure the HotStorage submission is using a different title
and a different system name from the Arxiv version. It would be useful to let
the chairs know if there is an Arxiv paper so that we can intervene if PC
members find it accidentally and think the submission is plagiarizing the Arxiv

Declaring and Avoiding Conflicts
When registering a submission, all its co-authors must provide information about
conflicts with the HotStorage ʼ23 program committee (PC) members. You are
conflicted with a member if: (1) you are currently employed at the same
institution, have been previously employed at the same institution within the
past two years, or are going to begin employment at the same institution within
six months; (2) you have a past or present association as thesis advisor or
advisee (no time limit); (3) you have collaborated on a project, publication,
grant proposal, or editorship within the past two years; or (4) you have spouse
or first-degree relative relations.

Do not declare a conflict if you discussed your research work with a PC member
before the HotStorage ʼ23 PC lists were publicized. Do not declare a conflict
merely because you wish to avoid a review from a specific committee member; such
unethical behavior might result in immediate rejection. All conflicts will be
reviewed to ensure the integrity of the reviewing process.

Authors and others are prohibited from directly or indirectly communicating with
any HotStorage ’23 PC member about any potentially submitted paper. All requests
should be made exclusively to chairs. Violations of these guidelines may seek
remedies as stipulated by the ACM.
