To improve the management of ANGEL's storage and future growth, beginning July 26, 2012, Information Technology Services (ITS) placed a cap on ANGEL course file space (1.5 GB), group file space (300 MB), and the number of groups (10) that each user can create.
The allocation cap on courses and groups enables Penn State to better utilize the available storage space in ANGEL, maintain system stability, and maximize the use of other ITS services, such as the streaming media server, which is designed to support the efficient delivery of specific content.
The allocation for course storage is 1.5 gigabyte (GB), which corresponds to the maximum size of a course that can be reliably imported and exported. Therefore, no additional storage space will be allotted. Faculty who approach the 1.5 GB limit may request a consultation (see below) to assess their use of the course space and determine whether this can be reduced through the use of ANGEL learning object repositories, master courses, or other ITS services. Exceeding this allocation cap will prevent faculty and students from being able to upload additional files, such as course content or attachments.
The initial storage allocation for groups is 300 megabytes (MB). The number of groups that each user can create is limited to ten.
These limitations meet the needs of 99 percent of ANGEL users. Users who reach these limits may request additional space and/or groups.
Processing Requests for Increased Group Allocations
Any requests by users for additional groups or group storage space beyond the initial allocation will necessitate a review of need and current usage (e.g., file types, content, and purpose) by ITS staff prior to approving increased allocations. Examples of legitimate requests for increased allocations are: expand course delivery (using groups as individual team space), collaborate on course development, advising, and research. As a result of this review, users may be asked to remove excess files and/or put some files in alternative storage services (such as PASS space). To request increased group allocations, a user must complete and submit the Request More Group Storage Space or Request More Groups form (see related articles).
To improve its management of Penn State's Course Management System, ANGEL, Information Technology Services (ITS) has issued a group storage policy affecting all users of ANGEL, including faculty, students, and staff.
ANGEL courses will be archived one year after the end of the academic semester in which they were offered. The one-year time frame is sufficient to resolve any deferred grades and grade changes based on Faculty Senate policies and GURU retention policies. Archived courses will be moved to long-term storage and will no longer be available to faculty and students. However, faculty can submit a request to recover a course in long-term storage using the ANGEL Support contact form. Turnaround time is two weeks. Archived courses will remain in long-term storage for two years before being permanently deleted. After permanent deletion, recovery will no longer be possible.
Archiving will occur at the end of each semester, approximately two weeks following commencement. At that time, the same semester from the prior year will be archived. For example, at the end of fall 2008, fall 2007 courses will be archived.
ANGEL groups are separate from courses. While courses last for a semester, groups are not tied to the academic calendar and can theoretically exist for years. To free storage space of groups no longer in use, the ITS ANGEL support team archives groups in which there has been low activity for six months or more. "Low activity" is defined as entrance into the group by group members fewer than twelve (12) times during a six-month period. Approximately thirty days prior to each archiving event, ITS will alert editors of the groups slated for archiving, giving them a chance to deselect groups for archiving so that they will remain active. This policy went into effect on February 20, 2009.
Archived groups can be restored upon request. They will be retained for two years, and then permanently deleted.
Master Courses and Learning Object Repositories
Master courses and learning object repositories no longer in use will be archived at the beginning of each spring semester, with the exception of repositories that are linked to from a course. Each year in early December, ITS will send an e-mail notification to the editors of master courses and learning object repositories, giving them the chance to deselect them for archiving. Any learning object repository that is linked to from a course will be excluded from archiving without any action required by editors. Archived repositories will be kept in long-term storage for another two years before being permanently deleted.
