Did you ever figure out a way around this? Seeing something very similar but with different devices.

Thanks for the comments. 1. From what I can tell there is at least some support for 4k disks in 5.5, at least it seems to know enough that if you create a datastore on a 4k disk it does the right thing partition wise. Installs though don't seem to work right, but like you said might be possible to manually format and install, though with I think 7+ partitions that get created on an install I don't think its worth dealing with. 2. The SAS2008 is basic, but also very cheap and actually works really well as a passthrough controller for ZFS in IT mode. I have two in this server, one in IT mode as passthrough and another in IR mode for booting and the datastore. The boot controller seems to work fairly well with a couple small SSDs in there, but not with any traditional disk drives, could be a caching issue like what you are pointing to. Re Side note: For whatever its worth I have 6 of the 3.5" Red Drives hooked up as ZFS raid-z2 setup and haven't had any issues with them over the last 6+ months. For a home server the price + 3 year warranty was enough to make me give them a try. For something more mission critical I would've gone with something else.
RAID 1 is courtesy of the SAS2008 (LSI brand), so should be fully supported and works fine with other drives in a similar RAID 1 configuration.

I'm trying to get ESXi 5.5 installed on a RAID 1 set of Western Digital 2.5" Red Drives on an SAS2008 controller. The problem I'm running into is that some part of the stack doesn't seem to realize that these drives are advanced format drives and the various partitions the installer creates aren't properly aligned. Any suggestions on how to force the installer to properly partition the drive?
