I’m going to call this a successful migration with a couple issues:

1)  I didn’t/forgot to set the block size of the vmfs when I installed ESXi.  The default is 1MB.  This means my virtual disks are limited to 256GB.  Not a big deal for now.  I plan on putting a set of 2TB disks on the controller as well at a later point in time and I’ll remember to set the block size to 8MB then.  As a workaround in the meantime, I’m just using dynamic disks on Windows when I need more than a 256GB disk.

2)  The Perc 6i card got hot.  It never failed or exploded, but it was hot enough to burn my finger the instant I touched the heatsink.  These things were meant to be in servers with airflow going over them, so that’s understandable.  I installed a 40mm chipset cooler to solve the heat issue.  Here are some pics:

Side shot.  Notice that I reused the clips from the original heatsink to attach the upgraded one.

This does take up the PCI slot immediately next to the controller, so keep that in mind if you decide to go this route.

So now I’m on ESXi 4.1 with 2TB of RAID10 storage.  I‘ve added a couple more servers and increased the memory on a couple others where before I was just completely maxed out in terms of memory capacity and couldn’t do anything more.  Huzzah!
