Temp Network Storage Service

Temporary Network Storage Services (Scratch Storage)

To get access to your own TNS space you need to apply via our Online Form [University sign-in required]

The service aims to provide on-demand access to large amounts of reasonably performing network storage at a low daily cost, for the temporary storage and manipulation of non-critical data. Users are able to consume several terabytes (TB) of data storage to allow further processing to occur before data is then transferred to an appropriate final location, such as the Research Data Storage Facility or Departmental Filestore, SharePoint etc. The service is not intended to support and must not be used for the long-term storage of any data and IT Services will automatically clean up data that is left within scratch areas outside of agreed periods.

What is the TNS service?

  • TNS offers an easy way to access large amounts of reasonably performing disc space without the need for staff to attempt to purchase their own hardware devices or use unsuitable devices such as USB hard disc drives to carry out processing or analysis. The TNS will not meet the needs of all staff for all purposes, but is faster and less expensive than many cloud storage services. The data stored is held on encrypted discs provided from secure data centre environments and is therefore more compliant with data processing restrictions than other services.

  • If you need to hold or archive data for the long term other storage options are available, such as the RDSF.

  • Data that would adversely affect the service (such as virtual machine disk files) should not be saved.

  • Users will need to complete the online application form to be given access to a scratch filing system exposed via either CIFS or NFS. Charges will be incurred are made dependent on the amount of storage that is used over a period of time. Space consumption is calculated daily and recharging would occur monthly..

Key Considerations

Data on this service has no guarantee of persistency: it is not a service intended to hold any data ‘at rest’ beyond an agreed period (default 30 days) and is not an archival service.

 • No data stored on this service will be backed up or regularly versioned.

 • Data will be automatically stored across multiple locations to guard against loss due to IT equipment failure or power outages and to ensure 99.5% availability.

 • IT Services will not be able to restore data that is deleted or overwritten by users

 • Data is stored encrypted “at-rest” and securely managed. However, users will be responsible for the management of their data and granting access to other members of the University.

• IT Services cannot guarantee that all sizes of data can be accommodated at all times as the service is shared for all users (e.g. requesting or attempting to consume 200TB may not be possible).

 Therefore, data stored on this PoC service should not be considered irreplaceable.

Who can use this service?

This service is a limited is currently open to staff (PGR) whose application indicates the service is suitable for their needs.  It is not available without application.

How can I access?

Scratch space can be provided via either CIFS (preferred) or NFS mounts.  If your application has been approved, you will be provided a connection URL\UNC path to access your storage area.

How much space do I have?

If your application has been approved, then you will have a flexible quota in line with your requirements; you can flexible use any amount of space within this boundary (e.g. 1TB-10TB).  At present the service provides up to 1TB of data at no cost. Each part TB of data used beyond this amount costs £0.40 per day, so using 1.5TB of data for 1 week would cost ~ £2.80. There are no ingress or egress charges (costs for accessing or retrieving your data).

Can I share my space?

Yes, the concept of the service is to allow the applicant (owner) to grant access to other members of the University to read/write the data.

Lifetime of the service?

We have run a Proof of Concept and pilot of the service for over six months to validate the operation of the system. Depending on the demand and costs to the University in providing scratch services,  we do reserve the right to provide a six months notice period to any TNS users.  This would mean that should we need to discontinue or retire the service all users have a guaranteed  period of access to allow them to move their data elsewhere.
