-We will install and support linux on any compatible workstation for you, following these guidelines.

-  * Your hardware must be directly supported by our version of Linux. +  * Your hardware must be directly supported by our Linux distribution, in particular without use of third party network or storage drivers

-    * Local user data must be stored on separate hard drives.  We value your data, and will not put it at risk by having it share space with the OS, where it may get overwritten by re-installations or updates. +    * Local user data must be stored on separate hard drives. We value your data, and will not put it at risk by having it share space with the OS, where it may get overwritten by re-partitioning during reinstalls or updates
-  * We do not share the root password to non IT-staff. If you have special needs, talk to us, we can usually make things work for you using ''sudo''.+    * "leftover" space on the primary system drive will be configured and available to users as "scratch" space
 +  * We do not share root passwords with non IT-staff. If you have special needs, talk to us, we can usually make things work for you using ''sudo''.

-===== Server and storage support ===== +
- +
-We would prefer to be involved in the purchase process for any server hardware we are expected to support. +
- +
-For small-scale data storage (a few TB), we support use of additional hard drives in any workstation or server (external drives, eg USB, are not supported for permanent storage). +
- +
-For large-scale (multi-TB) storage, we use a variety of technologies. +
-  * many groups use hardware RAID systems attached to our SAN (storage area network); this can be used to support storage in the 20-100TB range. +
-  * at slightly smaller scale, there is some use of internal hardware or software RAID in servers. +
-  * for specialized use cases, we are supporting hadoop HDFS for some research groups.+
  
-===== Operating System version information =====+Data storage on individual workstations is discouraged, as the data are generally not protected against drive failure, and is not backed up.
  
-Please refer to [[version_support|this page]] for more information on our supported versions of linux and the differences between them.+We expect to be involved in the purchase process for any server hardware we are expected to support.
