Will this work... 4TB Drives on PERC 6/iR controller and VMware ESXi 5.1 update 1

Here's what I have already:
I am running VMware ESXi 5.1 update 1
I have a PERC 6/iR raid controller in a Dell PowerEdge R410

Can I successfully add a 4TB drive to this system and have it fully recognized by raid controller and VMware?  Here are several potential drives I am looking at:

Any recommendations on these particular drives would be helpful too if you have an opinion.  I'm doing web hosting.

No.  The PERC 6/I supports a max of 2TB physical disks (and is a 3Gbps controller).  The H700 is supported in the R410 and WILL support larger than 2TB drives (and is also a 6Gbps controller).

Actually you can support a SAS drive > 2TB on that controller, but you can only do that in JBOD mode, and you would not be able to boot of those disks even if you did

Those disks can be reprogrammed as 2TB drives and then they would work with the RAID controller enabled .. but it would cost half your capacity.

So best to go with another controller that fully supports those disks in RAID mode.

So would this 2tb drive work? It's 6Gb/s, but would it still connect to my current controller at 3Gb/ s?

That drive is totally unacceptable, not because it is 6Gb but because the firmware isn't compatible.  Get yourself a 2TB SAS or SATA seagate constellation family drive.  SAS is preferred.

It is critical I have the right drive because I'm driving to a data enter for a scheduled upgrade. So just to make final sure, will this one work then???

"Actually you can support a SAS drive > 2TB on that controller, but you can only do that in JBOD mode, and you would not be able to boot of those disks even if you did"

The PERC 6/i does not support JBOD/non-RAID.  I think you might be thinking of the SAS 6/iR, which does support (not officially) >2TB drives in non-RAID/unconfigured mode.

DavidPresidentCommented:
Yes, the PERC6/i does support JBOD.  I know that for a fact because I have a PERC6 in my T7400 system configured with 2 SATA disks in JBOD, and 2 SAS disks in hardware RAID1.

I am running windows 7 on it, using the native software RAID1 as the boot drive, and the hardware RAID1 is sliced up into Solaris & Centos LINUX volumes. At times I have also hooked up a 3TB SAS drive in JBOD.

I assure you that it is fully transparent, true non-RAID JBOD.

"fully transparent, true non-RAID JBOD"

From Dell, stock and unmodified (because I'm sure you could) PERC 6/i (not a SAS 6/iR)?

Forgive me if I don't believe it? :)

DavidPresidentCommented:
PowerEdgeTech - I stand corrected. Thank you.  I have the SAS6/iR, not the PERC 6/i on my T7400.  

But the controller chip is the same. The 2TB limit is still a limit within the chip for SATA disks only.   I checked the programmers guide for the controller family and saw that while it is possible to do true JBOD on the PERC 6/i, the bit you have to flip to enable this is likely turned off by the Dell firmware.

I don't have a true PERC 6 with dell firmware here, so I can't use my developer's kit to confirm whether or not this is possible.

I appreciate the insight.  You're saying then that >2TB SAS disks will work on a PERC 6, in RAID mode? or just in the SAS 6's non-RAID mode and that >2TB SATA won't work?
