Historic CHARGING DETAILS​

ACCOUNT CHARGE - 2017-2025

All accounts will be subject to a service provision charge based on the number of accounts active in the previous year and the budgeted costs for running the computing facilities:

  • (Intended) Hardware Purchases - four year amortisation period
  • Staff costs
  • Third-party support costs (not disk/cluster related)
  • Third-party Service rental costs
  • Software licensing (not disk/cluster related)

Where an account is deemed to be a low usage account (less than ten gigabytes of disk allocation, less than one hour of compute usage) this fee will be capped at £100. The charge is pro rata, for example an account active for 6 months would pay 50% of the charge (i.e. £500 or £50 depending on usage).

 

DISK USAGE RENTAL FEE - 2017-2025

All accounts will be subject to a disk usage rental fee to cover the costs of providing data storage:

  • (Intended) Hardware Purchases - four year amortisation period
  • Tape purchase
  • Software licensing
  • Third-party support costs

This charge comprises of the following:

  • A low charge for disk space of any type allocated but unused
  • A medium charge for disk space used but unprotected by our data backup systems (scratch folder)
  • A higher charge for disk space used in one of the tape backup protected areas (home folders and /vols/Data)

CLUSTER USAGE CHARGES - Pre 2017

Where an account uses the compute cluster a charge will be levied on the cpu time used in the charging period for standard jobs, and on the wall time for interactive tasks.
