 Pound Sign Relatively cheap (about 60 per TB for 5 years read/write access followed by indefinite, read-only archiving. The actual price varies slightly depending on the current cost of disks - it can go up or down). 60 per TB is the price to use on grant applications.
Large volume Large-volume capacity on a managed system. (Individual research groups use single TBs to hundreds of TBs. Individual requests up to about 50TBs are fine - contact IT support to discuss anything larger).
Backups Backups - a single mirror with 30 days of changes ( see below for details).
Changed:
<
<
Performance Performance - the storage is on direct-attached, SATA disks, with an SSD read cache, served from 10Gbps networked servers.

 Disaster Recovery Disaster recovery - in the event of a major incident, it could take some time to restore all data from backups (possibly several weeks).

Security Security - the servers are housed in secure Faculty or University data centres and are rack-based. The system is behind the institutional firewall and has normal password security applied.

 Network Accessible as a network drive from all Faculty Windows and Linux desktops, and from Desktop Anywhere.

A Managed Storage System

Changed:
<

Calleo Server
 The Faculty offers a managed storage system for large volume research data. The system is classed as manged because Faculty IT carries out all the background activities associated with data storage:
  • purchasing the raw hardware
  • setting up filesystems and making them available on the network

Data Security

Changed:
<
<
The University Policy on safeguarding data should be applied when making decisions on data security. The Faculty system is behind the institutional firewall and has normal password protection. Data encryption is not applied.
>
>
The University Policy on safeguarding data should be applied when making decisions on data security. The Faculty servers are housed in secure Faculty or University data centers and are rack-based. The data centers have features such as intruder alarms, fire suppression, water detection, etc. The system is behind the institutional firewall and has normal password security applied. Data encryption is not applied by default.
 

Funding and Data Lifetime

Changed:
<
<
The funding for the Faculty storage system comes from individual research grants - the Faculty buys and maintains large servers as part of the central Faculty infrastructure, and research groups purchase the disks for these servers (including mirrors, backups, redundancy, etc) from grants. The cost to research groups changes with disk prices, but is currently around 60 per TB (depending on the backup policy - see below) for 5 years. (After 5 years, data on Faculty storage systems will move to read-only data repositories which are maintained as part of the over-all Faculty system. No time limit has been set on the lifetime of the repositories - that may be influenced by future University systems. Research groups should consider the long-term archive requirements of their data).

  Storage space can be purchased by contacting Faculty IT staff ( foe-support@leeds.ac.uk). Note that requests for storage up to about 50TB can follow the funding model above, but anything larger will require individual discussion with the Faculty IT team.
