Infrastructure Software

I am new to virtualization and especially Oracle VM. We have been waiting for Oracle VM 3.0 to come out so that we can build 64 bit hardware drivers (as opposed to 32 Bit in Dom0 on OVM 2.x) for Fusion IO solid state PCI based accelerator cards.

Our need to use Oracle VM at all is to do hard partitioning of CPU cores on our database server.

With that said, our intention is to have 2 new DL585 G7 servers (we have 10 core or 12 core CPU options), with 2 Fusion IO SSD (2.4 TB) inside one server, and a FiberChannel hard disc enclosure with 24TB of storage shareable between the two.

We strive for extreme data access performance for certain parts of our database system.

In playing with OVM 3.0 so far, I see that local storage (as the accelerator cards would show up as) is not really appropriate for Production Systems. It appears I can create a Repository on these physical disks and then present them to the VM guest. Then add these cards as my Oracle ASM disks for my "fast" storage, and do the same with the FiberChannel storage for my "slower" disks. Because of the Local Storage used for part of the VM guest, we would not be able to Live Migrate or have High availability I believe. Is this correct?

If we have the two servers as mentioned above. Could I take the database VM down and move it to the other server (ie Cold Migration)? The local storage (ie the accelerator cards) could physically be moved from one physical host to the other, but I am not sure, since this is virtualized disk, if this would be allowed or how it could be recognized on the other Oracle VM Server. This might be a "dream", but might be something we would like to do if an emergency arose or if more maintenance needed to be done on Server 1. Any comments?

Does anyone have other solutions to run Solid State disks (approximately 2TB worth) and Oracle VM, running a single guest that runs the database? We have been unable to find iSCSI or FiberChannel enclosures that can handle solid state drives in the 1 to 2 TB range of capacity. So perhaps there are other enclosures out there that can act as Shared Storage that can operate with SSDs. Thank you for any comments and suggestions.
