The library helps campus research labs and centers manage and publish their research data. We've worked with Information Management Systems & Services (IMSS) to put together a centralized Research Data FAQ.
Library staff can help you or your research group work through challenges associated with research data. We can provide:
- Data Management Plan (DMP) assistance
- Capacity planning
- Storage technology recommendations
- Suggestions for data processing and visualization
- Options for long term archival and data sharing
Contact us at data [at] library.caltech.edu or call x3827 to schedule a consultation appointment.
Data Preservation and DOIs
Our standard data preservation and DOI (permanant identifier) services are through CaltechDATA. We also offer services (at an additional cost) for preserving large volumes of data (> 500 GB). Contact us at data [at] library.caltech.edu to discuss the options.
Caltech Library also manages custom DOIs for groups on campus. Find out more information, see our DOI page.

Data Storage Hardware and Services
Network Attached Storage
Network attached storage devices are boxes that contain both storage and the hardware needed to manage the storage. They can be thought of as a small computer with lots of storage. Using a NAS to store your research data has many benefits. Because they are internet accessible, it is easy to centralize data collected on different instruments and to access data for later analysis. Most models contain multiple hard drives and can be set up with RAID to protect against data loss in case of a hard drive failure. NAS devices are generally affordable ($300-$1500 depending on the storage space needed) and is usually cheaper than purchasing cloud storage over 4-5 years. We currently provide instructions for setting up Synology NAS devices, but many manufacturers make a similar product. If you've got a different NAS, let us know at data [at] caltech.edu and we can work on putting together setup instructions.
Interested in trying out a NAS? Send an email to data [at] caltech.edu to get access to our demo NAS!
Caltech IMSS manages a campus site license for Box.com. Students get 50 GB of free storage, and faculty and staff can request unlimited storage at https://help.caltech.edu (request type IMSS > Data Storage & Backup > Request Additional File Storage > Box). Box.com is a good resource for storing backup copies of data and syncing between computers, but should not be used as a primary data storage location. Note that Box.com has a 5 GB individual file limit, and lacks a Linux sync client. Continued availability of Box.com is dependent on IMSS and Box. A comparison of IMSS provided file storage systems is available at http://imss.caltech.edu/services/collaboration-storage-backups/storage-comparison

High Performance Computing Resources
IMSS now provides centralized HPC resources via a campus cluster. There is a per-hour charge for computing, and research groups can make an investment to get additional computing time. Find all the details at hpc.caltech.edu
XSEDE is a National Science Foundation funded nationwide high performance computing resource. Researchers can request time on more than 10 national supercomputers, visualization resources, storage systems, and scientific gateways , also listed below. A separate NSF grant is not required to gain access to these resources. Caltech users interested in testing one of these systems can contact the Caltech Campus Champion, Tom Morrell at tmorrell [at] caltech.edu, for trial access. Faculty, Postdoctoral Researchers, and NSF Graduate Research Fellows can submit a startup allocation which provides up to 50,000 compute hours to test XSEDE resources. The startup allocation request process is very straightforward and enables users to quickly access computing resources. After one year or when the startup resources are exhausted, researchers can submit a more thorough research allocation proposal.

Cyverse (formerly iplant) is another NSF-funded cyberinfrastructure project that provided computing resources, primarily targeted at life science researchers. They offer free access to Atmosphere, a cloud-based computing resource where you can spin up computing resources with specific images. A basic allocation is available by registering, and additional allocations require an application.
