Have you deployed it yet?

Yes. It is in, but I don't know where we are right now with it. We're positioning our infrastructure to be adaptive [for when] we look at commitments to new vendors. That said, FCoE is definitely going to be relevant and important. We think it's part of the convergence that's happening in the data center, but I'm not sure we're ready to share our plans on that right now.

It's a very interesting technology. The power benefits it could yield is really intriguing, but I'd say we're not wholesale switching anything tomorrow. So it's on the radar. We'll continue to evaluate it and when we have the right vendor relationship, then we'll look at putting it in. From our perspective, there's still some questions around solid-state disk. Our general philosophy is never to be first. At the scale we're at we have to be thoughtful about anything we put into the environment both from an availability and resiliency perspective. So, I still want to make sure how SSD is going to play out.

Wells Fargo is a diverse organization with thousands of bank branches and retail brokerages. You're getting even more diverse with the Wachovia acquisition. How are you dealing with that kind of technology heterogeneity?

When we started a couple years ago, we put into our thinking that the entire data center is under pinned with the concept of supply and demand management. That's a different way of thinking for IT. Typically IT shops run a good supply shop. It's like that warehouse group that does a good job of optimizing all the boxes. As more stuff comes in, they you try to optimize it.
