Can't see local storage on HP ML350 G6

I've got a new HP ML350 G6, using the on board Smart Array p410i Raid Controller with 8 x 1TB SAS drives, configured in a RAID 1+0.  I've got ESXi 4.1 installed on a SD Card.  ESXi boots fine.

However, whenever I attempt to add the local storage, ESXi does not see the available storage.  ESXi does however properly detect the RAID controller.  Is there something I'm missing from the configuration?

The issue is the fact that you have >2TB of storage. I recommend creating separate pieces of storage (datastores) such that they are < 2TB (specifically 2TB - 512MB = aboug 1.94TB).

Ahhh, I think that is whats up.  I don't recall having the option to split up the array into datastores; I believe it might be a limitation of the p410i.  The server is at home; I'll have an update later tonight.

Create the array, and then split it up into what HP calls Logical Drives < 2TB. Available on most Smart Arrays.

Well, you'll have to split up the Array actually into different RAIDs. Just create different RAIDs that has no more than 1.94TB each.

And, I just wanted to make sure that the P400i card was on the HCL...it is, but it's only supported for 3.5 U5 and earlier versions of ESX/i. Another issue to be aware of...

Looks like I didn't realize that the p410i Raid Controller doesn't have memory to perform more complicated RAIDs nor split into logical drives.  I ordered a 256mb BBWC module for the p410i, set it to RAID5, and then used logical drives to set up several datastores.  Thanks for the help guys!
