This intensive course is focussed on teaching how to deploy and manage shared storage and server clusters that provide highly available network services to a mission-critical enterprise environment. The course will ensure that participants display a wide array of skills including improving application uptime by using high availability clustering, managing storage in a high availability environment using iSCSI initiators, HA-LVM or CLVM as appropriate, and GFS2 cluster file systems and implementing strategies to identify single points of failure in high availability clusters and eliminate them.
