Disk-array

Data storage and access

Data storage

The FACe disk array contains multiple disk drives including:

40 Tb dedicated to the clusters
10 Tb dedicated to project data-bases such as LisaPF
...

We also use the APC storage facilities such as :

10Tb /groups volume on apcdb01
...

Data access

There are several ways to access or share the data, depending on the desired access control.

Download/Upload

Groups can benefit from a repository in the Download/Upload APC space:

apcdb01:/groups/

The repository can be written by any group member, and accessed via the URL:

http://www.apc.univ-paris7.fr/Downloads/

Groups can choose to protect their repository using a login/passwd.

Webdav

The webdav system also offers a web access to the data but with a better control of user permissions (ie users have to authenticate themselves). The repository can be simply accessed via the URL:

https://apcwebdav.in2p3.fr/webdav/

or using specific client application, to get a direct read&write access. See http://en.wikipedia.org/wiki/WebDAV#WebDAV_client_applications for a list of client applications.

SSHFS

One has the possibility to mount a filesystem based on SSH very easily using SSHFS:

sshfs username@hostname: mountpoint

To unmount:

fusermount -u mountpoint

From outside, this requires to set a SSH tunnel beforehand:
