Individuals and/or units that have been granted access to University computer resources have a responsibility to use these resources in a responsible manner.
Disk space is a finite resource that is time-consuming and expensive to increase, and the scarcity of disk space can seriously impact all users of central computing systems. Therefore, it is prudent for all users to make efforts to conserve disk space at all times.
The use of disk quotas, which are disk space limits, is a proactive measure that allows for better management of disk space resources. By allocating a "fair" amount of space to each user, the larger population is protected from a scarcity of space due to monopolization by one or a few users.
Information Technology Services (ITS) applies disk quotas to all student, faculty, and staff accounts on systems managed by Information Technology Services (ITS).
Specific disk quotas vary by system and class of user. For file and print servers, each faculty and staff member is allocated 10 megabytes of disk space, by default. On the Osprey system, all students, faculty, and staff are allocated 100 megabytes of disk, by default.
Realizing that special needs do exist, Information Technology Services (ITS) will increase quotas for specific users, on a case-by-case basis. Procedures for requesting additional quota space are outlined below. However, additional drive space will be allocated only when the use is consistent with the Network Acceptable Use Policy.
Customers are asked to periodically review disk space utilization, and delete or off-load any unnecessary files. These may be documents that are no longer useful, or documents that are duplicated in several places.
Occasionally, a project will require larger amounts of disk space. Customers are urged to seek technical assistance to find out if there is a more efficient way to store data. Assistance is available from College and Division Tech, the Information Technology Services (ITS) Help Desk, or from the Center for Instruction, Research, and Technology (CIRT).
Students who need additional space for project work should have their instructor contact the Information Technology Services (ITS) Help Desk, at extension HELP, to submit the request. The purpose and duration for the increase must be stated. The Help Desk will refer the request to the appropriate systems administrator for completion.
After each semester end, a systems administrator will review all student accounts and will reinstate the default quota for all students who no longer need increased quotas, based on the instructor's original request.
Faculty and Staff who need additional space should contact the appropriate College or Division Tech, or the Information Technology Services (ITS) Help Desk. After initial discussion to establish the specific need and availability of resources, the request will be forwarded to the appropriate systems administrator for completion.
After each semester end, a systems administrator will review all faculty and staff accounts and will reinstate the default quota for all accounts who no longer need increased quotas, based on the original discussion and request.
FREQUENTLY ASKED QUESTIONS (FAQ):
- Are disk quotas really necessary?
Use of quotas is the most effective method available for managing a limited resource; for this reason, it is an industry standard practice. It helps to prevent the total exhaustion of disk resources, which would have an adverse impact on all customers.
- Can't you just add more drives to meet demand?
While the University upgrades servers on a regular basis, it is not possible to perform upgrades on a constant basis. Because these servers handle hundreds of users simultaneously, different technologies are employed from that of the average desktop computer. Performing server upgrades typically requires hours or even days of downtime, to ensure the safety and integrity of user files. Because such downtime can seriously impact University operation, it is nearly impossible to schedule such upgrades on an "as-needed" basis.
