Meeting title:

Storage Service Definitions

A short introduction describing the activities and the scope of the group:

This working group is involved in creating well-defined terms that describe storage services, especially in the areas of Quality of Service and Data Life-cycle. These terms should describe what the users (the scientists) can expect from the storage service, allowing them to compare different storage options and choose where to store their data with some confidence at how the storage service will behave.

The current lack of such standardised terminology makes it very difficult to compare the services and procure them. While Service Level Agreements (SLAs) and Memoranda of Understanding (MoUs) provide formal description of what the users may expect, the definition of those terms can vary between different communities and storage suppliers.  There have even been cases where the lack of a common understanding have resulted in litigation during a procurement process. To this end, this working group is building a vocabulary that describes aspects of a data storage service that user communities care about. The aim is that this vocabulary may be used both when interacting with computers (e.g., in network protocols) and producing textual documents (e.g., SLAs, MoUs) to bring a common understanding of what is on offer and what is required.

A related concept is the data lifecycle: how data is handled over its lifetime. Some of these processes may be automated, provided such steps can be described in a generic fashion.  By delegating these processes to some automated service, the scientists can focus on maximising their scientific output.  However, this (again) requires a common language that describes what should be done.  Such a language has multiple uses — it may be used when configuring storage or in higher-level documents such as a project's Data Management Plan (DMP).

The group will establish an efficient way to collect the terminology and use this to build the definitions. As the scope and the definitions themselves naturally evolve, versioning of the vocabulary will become necessary to support users that require isolation from such variability.

To be successful, this process needs to involve a community of international user, storage operators, as well as storage vendors and suppliers.  Representatives of all those groups are welcome to join this process.

The group is currently updating the case-statement, based on feedback from TAB, by strengthening those aspects that TAB identified.  Our intention is to submit the new case-statement around the time of P10.

Meeting objectives:

  • Continue work in providing a framework for storage service description.
  • Learn more about the tools that available to achieve this.
  • Attract more user communities.
  • Reach out to contacts in industry.

Meeting agenda:

  1. Introduction and summary from P9 meeting /15 min
  2. Outreach plans (industry and other scientific communities) with help from audence. /10 min
  3. ANDS / PoolParty — talk introducing their services (TBC)  /10 min
  4. Finalising the process/procedure for accepting terms - short discussion  /10 min
  5. Road-test procedure — adding a new term.  /10 min
  6. Agreeing next steps: /5 min

Target audience:

  • Scientists who care that their data is handled reliably, and in a cost-efficient fashion.
  • Facility managers who buy storage (hardware, services, "solutions", ...) that must meet the needs of their users.
  • Facility managers who are interested in making it easy for other scientific communities to use their resources.
  • People interested in the brokering storage for user communities, either manually or automatically.
