- | ===== Dedicated Shared storage server on Aurora ===== | + | ===== Basic rules ===== |
+ | |||
+ | Please follow these rules to keep the storage tidy. | ||
+ | |||
+ | - Whenever you need to move data to one of the shared folders below,\\ **create a folder with a name than can be understood by everyone** and put the data in there. | ||
+ | - If the data has been generated by you or if it is for your exclusive use, **create a folder with your username** to accomodate the data. \\ In this way you keep your data away from unwanted people and you can set all the permissions you want on it. | ||
+ | * Data found outside a folder named after a user it is a good candidate to be deleted. Of course there can be exceptions when needed. | ||
+ | - Remove data that you don't use, for example from the ''scratch'' folders. Be kind to your colleagues! storage has a cost. | ||
+ | - Follow the instructions at [[aurora_cluster:moving_data|Moving Data to and from the Aurora cluster]] when you start moving data around. | ||

- | Description yet to come. | + | Particle Physics can share data to the [[:iridium_cluster|Iridium Cluster]] and has two additional storage servers listed below for their exclusive use. |
- | ====== Storage on Iridium ====== | + | Users not belonging to the division of Particle Physics might be warned to remove their data from those storages, unless otherwise agreed with the Particle Physics division. |

+ | === Additional dedicated storage === | ||
+ | |||
+ | There are two storage servers installed for the exclusive use of particle physics. | ||
+ | The recommendation is to use these instead of ''/project/hep/nobackup'' so to give space to the other users of it. | ||

+ | === Grid storage === | ||
+ | |||
+ | Lunarc hosts a grid storage for ATLAS. Currently we are migrating from a 20TB storage to a 100TB. | ||

+ | The local storage name is | ||
+ | | ||
+ | | ||
+ | One can interact through it using the Rucio client. | ||
+ | |||
+ | Details on how to access this storage are at this page: http://www.hep.lu.se/grid/localgroupdisk.html | ||

+ | ===== Mathematical Physics ===== | ||

+ | At the moment, only the user folders are available. We are negotiating a 10TB common storage with Lunarc. More information is soon to come. |
