+== Storage ==
+ * Fast storage for camera streaming 
+  * First 8 TB on storage boxes attached to ipekatrinadei and ipepdvcompute1
+  * Exposed over ''iSER'' protocol using ''tgt'' server
+   * No access sharing, single user only 
+  * Both devices allocated to the camera computer using openiscsi
+  * Software Raid 0 is assembled from the devices
+  * Formatted using ''XFS'' and mounted under ''/mnt/server''
+ * Big and slow storage
+  * ''glusterfs'' is used currently, but ''fhgfs'' is faster and may be better option if they go open source (there are some plans)
+   * OpenSuSE packages does not include RDMA support, the source RPM should be recompiled on the system with installed Infiniband stack
+  * Storage mounted under ''/pdv''
+   * ''/pdv/home/'' clustered home folders
+   * ''/pdv/data/'' sample data sets
+  * External computers may mount the storage over NFS
