Central File Storage Policy for Faculty/Staff
(Highlighted text reflects changes since the previous version.)
1.0 Policy Statement
The Wellesley College Central File Storage Policy for Faculty/Staff outlines the multiple central file storage options available for Wellesley College faculty and staff in order to address the growing need for greater file storage.
As the use of technology for scholarly purposes and the need for collection of data continues to increase, the need for greater file storage has increased as well. For example, some faculty have very large quantities of data (e.g., research sets) that are too large to store on a local disk or central file server. When a centrally managed file storage option is not sufficient, some Wellesley College faculty and staff have opted to manage their own file server.
Distributed file server management outside of Library & Technology Services (LTS) creates multiple potential issues: insecure storage of data; incompatibilities with approved computer configurations; little or no back-up of data; duplication of stored data; inability to share data among departments; and issues with providing hardware support. This policy intends to address these concerns through offering centrally managed file storage options that meet the needs for both small and large data storage.
This policy applies to all Wellesley College faculty and staff.
Library and Technology Services will provide secure file storage space, maintain the servers and provide back-up for the data. The Chief Information Officer has responsibility for this policy.
5.2 General Policy
Library & Technology Services provides the following options for faculty and staff:
On campus storage on NTM
On campus storage on Vault
On campus secondary storage via academicstore
Off campus storage on Amazon S3 or Glacier
For more information, see http://www.wellesley.edu/lts/techsupport/filestorage
On Campus storage - NTM
Each Wellesley College faculty and staff member will be eligible for 7 GB of storage on NTM. Additionally, each department will be eligible for 30 GB of shared storage on NTM. NTM storage is considered “primary storage” in that it is located on high performance, and highly redundant, disks. As this space is limited, Wellesley College will strictly enforce quotas stated above. The individual employee space is to be used for important documents that can be accessed from multiple locations and the department space is to be used for sharing and collaborating with others at Wellesley College. Through SSL VPN, NTM is accessible from home and other remote locations, which makes this is a viable shared storage option for many employees.
On Campus storage - Vault
Vault is considered secure storage, and all confidential college data, including personally identifiable information, must be stored here. For more information see the College’s Written Information Security Program. Through secure SSL VPN, Vault is accessible from home and other remote locations, which makes this is a viable shared storage option for many employees. See the College’s Remote Access Policy for information about accessing secure data from home.
Faculty members can use Sakai Resources to store documents used for teaching, and all employees can use MyWorkspace and Project Sites for the work of the College. Each of these Sakai sites has a default storage quota of 1 GB.
All employees can store an unlimited amount of College-related data in their Wellesley Apps for Education Google Drive account. Each Google account has a default storage quota of 30 GB (combined between Mail and Drive).
On Campus Secondary Storage via academicstore
Some faculty members and administrative departments have a need to store very large quantities (100s of Gigabytes to Terabytes) of data. In some cases, these data sets are actively used, and in other cases, they are archived. NSF now requires that the College have a Data Management Plan that needs to be specified in the grant proposal. This plan would outline how the College will disseminate data related to research to the public, if funded.
LTS provides "secondary storage" to departments through an approval process.
Faculty and staff in need of additional storage should complete our online storage request form. Faculty requests are reviewed by the Provost's Office and staff requests are reviewed by LTS before allocation.
Off Campus File Storage in Amazon S3 or Glacier
An alternative to on-campus file storage is moving that data to “the cloud.” The cloud refers to a series of connected servers distributed throughout the country that are accessed through the internet. There are many instances where the requirements for large data file storage can be easily met by off site storage in the cloud. LTS recommends the use of Amazon S3 because it is one of the most reliable services. There are considerable unknowns about this option with respect to the transfer speeds of large data sets, the cost (which depends on the data transfer), convenience for access, etc. However, overall it will be a less expensive option because it is not necessary to purchase any hardware or allocate staff resources for maintaining it. LTS will administer the program for anyone who wishes to use it. There will be a full chargeback to the faculty or department for use of Amazon S3. Amazon Glacier is another alternative that is less costly, but is ideal for long-term archival given the charges applicable during file retrieval.
LTS has also commissioned a test system on Amazon EC2. For those faculty wishing to run data analysis on data stored in the cloud, LTS can potentially commission another computer in the Amazon Cloud to run the software (assuming that the software license allows for this). If the data contains human subject data or labor statistics, this model will not be viable due to security concerns.
For the storage of research sets that involve chargeback, LTS will work with the faculty to determine if the cost of storage can be built into the grant proposals.
Misuse of the data storage options listed above or any other failure to comply with this policy could result in loss of privilege to use the space. Storage space options are subject to change as the technology that supports them changes and newer technologies become available.
