Overview

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.

Topics of Interest

HotStorage '25 welcomes innovative submissions in the broad areas of storage, data management, data applications, and cross-disciplinary topics that relate to these. Some specific areas include, but are not limited to:

• Application- and workload-specific storage
• Archival and backup storage
• Deduplication and compression
• 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 storage (sensors, home, IoT, etc.)
• 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 virtualization
• Storage systems for ML and applying ML to storage systems

What to Expect from the Workshop

HotStorage ’25 will be a two-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 at chairs25@hotstorage.org.

Submission Instructions

Submissions must be no longer than five (5) two-column pages excluding references and appendices. They should be submitted electronically via the submission form at https://hotstorage25.hotcrp.com/.

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, e.g., "Position: XYZ".

Formatting Guidelines

Papers must be typeset using a 10-point font (Times New Roman or similar) with a 12-point (single-spaced) leading, fitting within a 7"x9" text block using two columns with 0.33 inches of separation.

Originality

Submissions to HotStorage ’25 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. We follow the ACM Prior Publication and Simultaneous Submissions Policy. Questions? Contact the program chairs.

Anonymizing

The review process is double-blind. Authors must not be identified in submissions, either explicitly or by implication. Papers from industry may identify the company or the product. Papers accompanied by nondisclosure agreement forms will not be considered.

Declaring and Avoiding Conflicts

When registering a submission, all co-authors must provide information about conflicts with the program committee (PC) members. Conflicts exist if you:

• Work at the same institution as a PC member
• Have collaborated on a project, publication, or grant within the past two years
• Have an advisor/advisee relationship (past or present) with a PC member
• Have family relations with a PC member

All conflicts will be reviewed to ensure integrity. Direct or indirect communication with PC members about a submission is prohibited.

ACM Publications Policies

By submitting your article to an ACM Publication, you are hereby acknowledging that you and your co-authors are subject to all ACM Publications Policies, including ACM's new Publications Policy on Research Involving Human Participants and Subjects. Alleged violations of this policy or any ACM Publications Policy will be investigated by ACM and may result in a full retraction of your paper, in addition to other potential penalties, as per ACM Publications Policy.

Please ensure that you and your co-authors obtain an ORCID ID, so you can complete the publishing process for your accepted paper. ACM has been involved in ORCID from the start and we have recently made a commitment to collect ORCID IDs from all of our published authors. We are committed to improve author discoverability, ensure proper attribution and contribute to ongoing community efforts around name normalization; your ORCID ID will help in these efforts.
