Deploy a highly available, low-cost Oracle 12c RAC cluster by discarding shared storage

With a lot of Oracle RAC, shared storage is used. Dual controller with full disk, 15000 rpm SAS full slot, made into RAID 10, the cost is still very large. Recently in the open source hyper-fusion test, has achieved the very ideal effect: to be centralized, high availability, open source and low cost, can realize any one physical machine failure, run its virtual machine on the automatic drift. It not only solves the high availability of server virtualization, but also integrates desktop virtualization.

That's why I wanted to deploy Oracle 12c RAC with this platform, without the need for shared storage, which is much higher availability than plug-in storage, and the IO load is much lower than shared storage. The general plan is this:
1. Prepare 3-4 physical servers with exactly the same configuration and at least two NICs.
2, the physical server to form a decentralized cluster, and the deployment of a well-integrated distributed File System Ceph.
3. Create several virtual machines, distributed in different physical host.
4, choose three virtual machines, these virtual machine on different physical host server. Of these, two are used to install Oracle software, and the remaining virtual machine installs Openfiler as an iSCSI service. Ceph can be used directly for Oracle, but it is also cumbersome to configure.

Assuming any physical server fails, the virtual machine on which it is running, regardless of the application, will automatically fail over to ensure the availability of the business. Lucky to get the strong support of Chi-super brother, improve a performance Proxmox cluster environment.

Good guy, six nodes, as long as there are 2 physical servers alive, the rest of the machine is all right to die.
