Jim Cramer’s “Mad Money” featured an interesting segment yesterday, titled “Sell Block: The Death of the Data Center?”

Basically, the premise of the segment is that Intel’s Nehalem DP processors will allow businessses to shrink their data center footprint, and thus businesses won’t need as much data center space, commercial data centers will empty out, and businesses might even bring previously colocated gear back into in-house data centers. He claims, somewhat weirdly, that because the Wall Street analysts who cover this space are primarily telco analysts, they’re not thinking about the impact of compute density on the growth of data center space.

I started to write a “Jim Cramer has no idea what he’s talking about” post, but I saw that Rich Miller over at Data Center Knowledge beat me to it.

Processing power has been increasing exponentially forever, but data center needs have grown even more quickly — certainly in the exponential-growth dot-com world, but even in the enterprise. There’s no reason to believe that this next generation of chips changes that at all, and it’s certainly not backed up by survey data from enterprise buyers, much less rapidly-growing dot-coms.

Cramer also seems to fail to understand the fundamental value proposition of Equinix in particular. It’s not about providing the space more cheaply; it’s about the ability to interconnect to lots of networks. That’s why companies like Google, Microsoft, etc. have built their own data centers in places where there’s cheap power — but continued to leave edge footprints and interconnect within Equinix and other high-network-density facilities.
