After a long hiatus finally found something exciting to crib about. Just completed India's first Exadata Oracle Virtual Environment (OVM) setup.
It's a departure from the traditional Exadata Setup where you directly utilized the entire capacity of the two (or more) compute nodes and created RAC databases on it.
With this new setup here is a list of new possibilities and the basic architecture.
More stuff coming up shortly........
1. something called as DOM 0 or domain zero virtual machines comes up on BOTH the compute nodes of Exadata when you first configure the RACK.
2. Hence forth you will always login to the IP assigned to DOM 0 on node 1 and node 2 to carry out all future setups.
3. DOM 0 is the mother or controller of all user defined virtual machines that will come up on the compute nodes.
4. It is using the XEN Hypervisor virtualization engine.
5. Currently if you want to configure virtual machines. OEDA i.e. ORACLE EXADATA DEPLOYMENT ASSISTANT is the only tool. You configure your entire setup i.e. assigning IP address defining cluster names, diskgroup names and size etc in this tool. FTP the generated files on
/EXAVMIMAGES/linux-x86/ folder on dom 0 of compute node 1 and run ./install.sh -cf setup.xml -s 3
6. You fire up the step 3 of install.sh for any further vm creation.
7. Multiple IP segments can be created . i.e you can have one VM running ip segment 172.16. and other vm running 172.18.....
8. All VMs in a cluster should be under the same IP segment.
9. VLAN tagging is required at customer data center switch level to allow multiple IP segment.
10. Gateway of IP segment to be created must be pingable from the defined IP addresses. If your customer uses firewall at data center switch, ensure that he allows ping to gateway IP from the configured IP addresses.
