Red Hat Storage Server Administration (RH236)





Deploy scalable, highly available storage on off-the-shelf hardware and in the cloud
This course is for senior system administrators and storage administrators who are interested in deploying scalable, highly available storage on off-the-shelf hardware and in the cloud.
Students will learn how to install, configure, and maintain a cluster of Red Hat Storage servers. The course will also explore highly available common Internet file systems (CIFS) and network file systems (NFS) using CTDB, unified file and object storage, and geo-replication.
Note: Red Hat Storage Server Administration is part of our new emerging technology series of courses. These courses focus on Red Hat's newer, evolving technologies. Emerging technologies courses are feature- and functionality-focused and are conducted like guided labs, with little lecture. For more information about these courses
