Increasing Your Disk Quota

Increasing Your Disk Quota

All students are given a disk quota. This is the limit for how much data you can store on your network drive (the R: drive on the Windows PCs). This is set at 20GB per user as of the summer of 2012. Disk quotas are our way of making sure that a few users don't fill up the disks which everybody must use. Its also our way to ensure the expensive server resources are effectively used.

Many research groups in ME have compute and storage servers as well. These machine tend not to be backed up but they also do not usually have quota limitations. If you group has such a machine(s), you may find hundreds of gigabytes or more of space available.

Another common solution is the use of flash drives. As of the summer of 2013, flash drives can be purchased with capacities of 64GB or more with the smaller 4GB-8GB given out free by various companies as promotions. These provide a convenient tool to move data without requiring any network connections for access.

If you just need temporary space, you can use the C:\Temp or D:\Temp directories on the PCs or the /tmp directory on tools or widget or your ITAP career account space. You can also burn some of your files onto a CD or DVD disk. Lastly, drive space provided by your research groups is significantly cheaper than drive space we can provide on tools.

If you need more space in your account, there is a procedure to follow:

  1. Make sure you are only storing current course-related or research material in your account.

    • We simply can't hand out more disk space to users who have their account full of pictures of their cat or the hottest new MP3 files. We also cannot provide space to keep your entire academic history at Purdue. (We'll check!)

  2. Burn any archived materials to CD's or DVD's. You do not need to store your entire literature search on your account for access.

    • This can usually reduce your disk usage up to around 50%. (We'll check this too!)

  3. Use flash drives or portable hard drives to transfer large datasets between lab machines

    • If you are doing serial computations on multiple windows machines, you do not need to store all of the data sets on your computer account. Large flash drives and portable hard drives are a far more efficient use of space..

  4. Utilize the BoilerBack Pack - Available mid-late 2013.

    • ITAP provides a cloud based fileserver with 100GB of cloud available storage per user. This service should be available in mid-2013

  5. Utilize the Fortress DXUL tape server.

    • ITAP provides a tape archive based fileserver named fortress for storing immense data sets with network access. Account can be requested from the RCAC group at ITAP.

  6. Come into Technical Services (ME 2042) and fill out a "Resource Change Request" form to increase your quota.

    • We will want to talk to you to find out what you need the space for. If it's for a legitimate reason, we have no problem with giving you more space.
