I was being a little tongue in cheek in my original post, following along with the previous poster. My only comment about proprietary is that I can't call up Oracle and buy the exadata software license and then install it on any machine I want, or with any storage I want. Is that *really* proprietary? Well, it's certainly inflexible. None of this is a knock on exadata - I was just continuing in Robert's vein of pointing out that the original user gave almost no boundaries or parameters for what they're looking for. And yes, you can run the Exadata software on a VM, though you obviously lose the InfiniBand RDMA performance enhancements.

Yes, SUN/HP install and configure the HW but this typical for most HW vendors of middle to high end installs. This is also typical of disk array vendors as well. Oracle Advanced Customer Support (ACS) does a basic install and creates a skeleton DB and that is all. Oracle consulting is typically not engaged in exdata unless the customer asks for consulting. After this install then the environment is yours. You can tune and manage this environment just like you would any Oracle environment. The only thing is that exdata comes with void the warranty rules. Oracle has some strict rules for exadata HW. 1. No one else can plug into the infiband network 2. No other equipment other than SUN/HP in the rack. If the Cell cmcli packages where not tied to the infiniband firmware you could build this on your own with any network. I have not personally done this but you should be able to build an exadata environment out of virtualized environments. If you don't want to follow these rules then you can just by the equipment piecemeal just as we have for years. My original point is that exadata is no more proprietary than any other HW vendor. At this time exadata is a niche product and trying to move into a all purpose product with V2. In general the rack configuration you want is what you can afford. If you are just testing then Ebay is great place. You can buy and setup 3 linux quad cores for under $1500. Use 1 box as an iscsi target and the other 2 as a cluster. I bought 2 SUN U60's and a D1000 off of ebay in 2002 and they still run like champs.

Only Oracle support and consultants can install, configure, modify an Exadata/DB Machine software platform. So why learn something when you cannot ever touch it...? Probably that is wgar Mat means Thanks On Sun, Jan 24, 2010 at 6:44 AM, Scott Heisey <oraracdba@xxxxxxxxx> wrote: Matt, Just out of curiosity, what makes exadata proprietary? The version of Oracle on exdata is not special and neither is linux. You are stuck with HP or SUN as the vendor infiniband for the network and there is specific HBA that is used. I wouldn't call exdata any more proprietary than IBM HW. However exadata is a HW solution for a particular application like DWH.

Personally, I'd say skip the Exadata platform - why lock yourself into a proprietary architecture? Buy 100 2 x 4-core processor servers with 48GB of RAM each. That should give you a really good sense of whether your application will scale in RAC environments. Of course, to make sure I/O doesn't become a bottleneck, I'd recommend a 2000-disk EMC VMAX with a mix of flash and fibre channel drives. Each one of the servers should have at least 4 4-Gb/sec links into the SAN. This is just for the development environment, of course. Or, the OP could just google "oracle rac test environment" and see the options presented. For me, the third one is "Build Your Own Oracle RAC Cluster on Oracle Enterprise Linux and iSCSI", which definitely won't be as fast as our solutions, but is almost certainly cheaper. Or, the sixth option down the page is a presention by the always-popular Dan Norris on building a RAC environment with VMware.
