Storage Options

This page describes the main options for you to store your research data and program code at Kellogg and helps you to choose which resource is right for your situation.

Kellogg Linux Cluster

Home Directory

Your account on the KLC comes with a home directory. Its quota is 80 GB there, and your data there will be backed up. Permissions on your home directory are set such that only you may read or write files there.

The home directory is good for storing code and relatively small datasets. It is not a good location for files that you want to share with others.

Project Directories

You can request a project directory on KLC. There are no storage quotas on project directories; however, Kellogg does have a global quota, which is currently 160 TB. We ask users to be mindful of this and to conserve space whenever possible.

Permissions in project directories can be configured any way you like. Please ask Research Support to set one up for you if interested.

KLC project directories currently are not backed up. We strongly encourage users to maintain their own back-up copies of essential files elsewhere.

Kellogg Data Center

KAP02 Windows Server

Some researchers prefer to work on the Windows server kap02.kellogg.northwestern.edu – sometimes called the “application server” or “KDC.” On KAP02, you have a “User” folder on the U:\ drive, and you might also have access to a “Project” folder on the P:\ drive. 

Please ask Research Support to set one up for you if interested.

Although there are no hard quotas on these directories, we ask most users to keep less than 100 GB in their User and Projects folders since space on KAP02 is relatively constrained. 

KDC02 SQL Server

KDC02 is a back-end storage facility primarily used to host large datasets as SQL Server databases.   Most users will never store files here themselves because, in general, Research Support creates and updates the databases on KDC02.  In some cases, however, research teams have asked to administer their own SQL Server databases there.

Please contact Research Support to discuss whether KDC02 or another option is right for you, to have a SQL Server database created, or to request access to an existing database.  

Secure Data Options


Research Data Storage Services (RDSS) is a service by NUIT that allows you to store research files for a fee.  You have the option of placing your data in a Non-Audited or an Audited zone.  The Audited zone is appropriate for storing regulated data such as HIPAA or PHI.

RDSS volumes are backed up, and they accept network drive mapping.

H: Drive on KAP02  

The KAP02 Windows server also contains a secure partition that is appropriate for many types of regulated data.  Please ask Research Support for a consultation to see whether this is a viable solution for you.

The H: drive is not backed up, and to work with the files there, you need to use the resources on KAP02.


Box SAFER is an extension of Box that was developed at Northwestern University.  It effectively enhances the security so that you may use Box for storing regulated data.

Most groups use Box SAFER for storing sensitive administrative data.  This can be a good option for certain small research datasets.  However, if you need access to special software or large computational resources, other options will be better.
