While creating bricks on SSD devices would be ideal for performance, this is often not practical due to cost factors. All of this in a hosting setting. In oVirt / RHEV terms, storage domain is defined as a repository disk images used by virtual machines for system boot disks, data storage, or as installation media. Different types of storage domains (iSCSI, NFS, FC, POSIX, and Gluster) can be added to the same data center. NFS-enabled storage, or can you confgiure local storage on ovirt-node and install the engine to there? 3. ISO oVirt Node 4. It allows you to define hosts, configure data centers, add storage, define networks, create virtual machines, manage user permissions and use templates from one central location. 11 ovirt CVM utilizes local storage to create replicated shared storage connected to oVirt nodes via iSCSI.
