Oracle Database Appliance 2.5 And Virtualization (Updated)

So the cats out of the bag and Oracle has finally announced that Jan 31st ODA 2.5 will be available. The ODA 2.5 is a pretty significant update to the ODA Platform. it will have 1. Virtualization as an option with OVM 3.1.1 2. Official External ASR management. So The virtualization is huge since it allows for using the capacity of the ODA for things other than the Database. The concept is a DOM0 and an ODA_BASE which is a privileged domain that ensures that The Database Appliance performs optimally. Intially the DOMU or user Domain will not have access to ASM Disks or ACFS mounts but that is something that will show up in a future release . The User Domain will not be patched as part of the Single Patching technique which mean if you go with virtualization the user domain needs to be patched independently. Also initially only 250GB extra slice is the only space available for the DOM0 and DOMU areas. This can bring in a little more complexity but from a DR perspective it helps in building idle capacity with a smaller footprint . The question that is important is should ODA deployments start with a Virtual deployment even though there might be no requirement for it initially. Oracle will ship the physical deployment and customers can bare metal it to be virtualized. Oracle Claims to be able to provide virtualization with ease of use but only time will tell. I am pretty excited about this since i can build virtualized boxes and do DR at a cheaper cost but the same horse power that i need. I do intend to test this and see how the ease of use to determine if that is my goign in stance for all new ODA deployments . Update: The Database Appliance has 500GB of Local Disk space which means DOM0 and DOMU will have access to 250GB and ODA_BASE will have 250GB available to it.
