Storage
=======
There are two main shared file systems on Anselm cluster, the [HOME](../storage/#home) and [SCRATCH](../storage/#scratch). All login and compute nodes may access same data on shared filesystems. Compute nodes are also equipped with local (non-shared) scratch, ramdisk and tmp filesystems.

Archiving
---------
Please don't use shared filesystems as a backup for large amount of data or long-term archiving mean. The academic staff and students of research institutions in the Czech Republic can use [CESNET storage service](../storage/#cesnet-data-storage), which is available via SSHFS.

Shared Filesystems
------------------
Anselm computer provides two main shared filesystems, the [HOME filesystem](../storage.html#home) and the [SCRATCH filesystem](../storage/#scratch). Both HOME and SCRATCH filesystems are realized as a parallel Lustre filesystem. Both shared file systems are accessible via the Infiniband network. Extended ACLs are provided on both Lustre filesystems for the purpose of sharing data with other users using fine-grained control.

Shared Filesystems
----------------------
Salomon computer provides two main shared filesystems, the [ HOME filesystem](storage/#home-filesystem) and the [SCRATCH filesystem](storage/#scratch-filesystem). The SCRATCH filesystem is partitioned to [WORK and TEMP workspaces](storage/#shared-workspaces). The HOME filesystem is realized as a tiered NFS disk storage. The SCRATCH filesystem is realized as a parallel Lustre filesystem. Both shared file systems are accessible via the Infiniband network. Extended ACLs are provided on both HOME/SCRATCH filesystems for the purpose of sharing data with other users using fine-grained control.

###HOME filesystem
The HOME filesystem is realized as a Tiered filesystem, exported via NFS. The first tier has capacity 100TB, second tier has capacity 400TB. The filesystem is available on all login and computational nodes. The Home filesystem hosts the [HOME workspace](storage/#home).

###SCRATCH filesystem
The  architecture of Lustre on Salomon is composed of two metadata servers (MDS) and six data/object storage servers (OSS). Accessible capacity is 1.69 PB, shared among all users. The SCRATCH filesystem hosts the [WORK and TEMP workspaces](storage/#shared-workspaces).
