RHEV supports multiple storage types, such as FC, iSCSI, NFS, local storage, POSIX Complaint, and Gluster File System. Note that you can't mix up different storage types in a data center on RHEV 3.3. In RHEV, there are three different storage domains:
Data domain: This is used to store the virtual machines' images, snapshots, and templates
ISO domain: This is used to store the operating system library for virtual machine deployment as well as the virtual floppy drive
Export/Import domain: This is used to back up all your virtual machine images and use the same disk as an import domain to move your virtual workloads across the data centers in the same or other RHEV environments
In this guide, we are going to use the storage type of iSCSI for our data storage domains, and NFS disks for ISO and export/import domains. Please refer to Chapter 10, Setting Up iSCSI, NFS, and IdM Directory Services for RHEV, to set up your own NFS and iSCSI server on RHEL to serve ISO, export storage...
