Original discussion courtesy of Larry Grant:
I'm repeatedly being asked why a customer would rather run Oracle on a Vblock vs an Exadata machine, so I thought I'd give some of my opinions on the subject.
Feel that Exadata is an appliance designed for a specific usercase, BW, Dataminer, OLAP, VBlock is an integrated platform optimized for DC / Virtualization environment, and suit for various usercases.
As WebSphere CloudBurst Appliance, I believe Exadata is easy to access at first.But the risk is future scalability. IT industry is innovative, we always not sure what to get next. Although we can have a provisioning by few clicks with Tivoli Provisioning Manager + VMware + CloudBurst(one of solution I ever met), we always feel worried on Exadata locked by RMAN, DataGuard and similar Oracle weapons. Vblock is open, evolutional and wise choice.
I am in full agreement with item two of the "Why Vblock" list, "Unlike Exadata, you aren't limited to what applications you run, including; Oracle Database, Oracle Weblogic, other Oracle apps, as well as non Oracle apps such as Websphere, Tomcat, Apache, MS Exchange, MS Sharepoint, Windows, Linux, and other software."
However, I'd like to throw this out there: I think it's a bit misleading to lump Exadata in as a simple appliance. Oracle is the backbone of so many data centers that dismissing it with a, "It's just an Oracle appliance" is a bit pedestrian. Since Oracle can handle warehousing, OLTP, document managment, SAP databases, ect etc etc etc how well is the "it can only do one thing" going to really hold up when talking to the app owner who needs various Oracle instances to run their business? Additionally, Exadata doesn't really have a problem with scale. It can grow to handle fairly robust workloads.
If it was me in front of a customer I'd focus on all the other great items in the list and toss in the "and you can run other applications/databases on Vblock as well" as a differentiator. That wouldn't be my focus point.
There's my two cents. Thoughts?
Cost is significantly lower when you compare Exadata with Vblock. One of the key contributor is that you can shape the Vblock to what customer budget is and leave out the option of RAC from all the blades. I had done a quick comparison and it looked like customers can save a bundle.
Jeff, great summary!
I would to see Application Consistency added to this - kind of sticks with Customer mind easily when you mention that 2 databases on the same Exadata are not consistent with remote replication.
Can you elaborate on your point? It's huge and I'd love to hear more about application consistency within Exadata.
Once upon a time my job was writing the scripts to do DR and so this kinda thing really tweaks my interest.
You might find the VCE battle card contains some of that information in a distilled format:

I also worked with VCE teams that did a side by side comparison of Vblock and the Oracle box to arrive at some of this information and they did an amazing job. I don't think replies support attachments but if there is interest I can put you in touch with the sales pursuit teams at EMC.
