What are different storage areas for (/home /data /scratch /tape etc)?

/home - Storage for your program code, submission scripts. This is network-based storage. (25GB / user)
/data - This is a storage area for application input and output files. This is network-based storage. (50GB / user)
/scratch - High performance storage used for storing temporary input and output files while a job is running. This is local node storage.
 
Reading input or writing output files to /home is strictly prohibited.
For MPI jobs please use /data.
For sequential jobs please make use of scratch storage. Scratch storage is much faster than network storage, so jobs will complete quicker.

Will you host my database for me?

We currently do not offer a database hosting solution, however, we are able to offer custom solutions. Contact the help desk for details.

What stops me using more than 25GB on home and 50GB on data?

Quotas.

What the heck is a Quota?
A quota is a restriction that is placed on the amount of data an account may use.
A quota consists of a soft/hard quota and a grace period.
A soft quota is a predetermined level where a warning email is sent out. This however does not prevent you writing more data until the grace period is reached.
A grace period is the amount of time you are allowed to go over the soft limit before the system blocks your ability to write more data.
A hard quota is a predetermined level where the system blocks your ability to write more data. You will still however be able to read your data.

Could I have an example of the Quota system?:
Scenario 1 -
I have 20GB of data in my home directory. I copy another 10GB to my home directory.
So I now have 30GB of data which means I'm 5GB over the soft limit. I receive an email stating I have gone over the quota.
A counter is now started on the server which is called the grace period.
I now have 7 days to reduce my data back down below 25GB (the soft limit). However I can still keep my data at 30GB safely for a week.

Scenario 2 -
I have 30GB of data in my home directory and I decide to copy another 25GB. As soon as I reach 50GB of usage on my home directory, the system stops me writing anymore data.
The copy / scp / rsync command would return an error "quota has been exceeded".

Scenario 3 -
I have 30GB of data in my home directory and I forget to reduce the data below 25G. The 7 day grace period then expires.
The 25GB soft limit now becomes a hard limit. I will be unable to write anymore data to my home directory until I reduce my usage below 25GB.
