436 CLUSTER TRAINING

Red Hat Enterprise Clustering and Storage Training help an administrator to maintain and manage the ISCSI storage, UDEV rules maintenance, and multi-path, the web-user interface which provides you the easy maintenance of cluster. The main attraction is the web-user interface, which provides easy maintenance of the cluster and storage through the GUI mode and also explains about the leading file system in clustering and storage i.e., the Global File System 2 and common cluster issues.
