ESXi4 Dell R410 Only showing 41.25 GB

[SurfNshoot]

Ok I'm totally new to this so don't beat me up to hard if this is something simple. Which I hope it is.

I have a Dell R410 setup in a raid 5 with 4 750 drives on a Perc/6i addapter. When I install ESXi4 it shows the full 2tb of space but when I look at the datastore it only shows 41.25GB.  I do see the 2.05tb dell disk in the devices but when I try to create a datastore it does not show as available.

what might I be doing wrong here?

Thanks

Hello.

The greater than 2TB-512 bytes volume is the problem. This is documented in kb 3371739.

Good Luck!

With the Perc 6i two logical drives can be created on the raid-5 set, one say 45GB and another with the remainder to bring it just under the 2TB limit.  But, create only the first (small) logical drive before running the installer, since the installer tends to have problems picking the right LUN on this controller.

As an aside though the machine will perform much better with a RAID-10 configuration.

Thanks guys!!!!! I reconfigured to raid 10 and now have a 1.36T datastore. I'm off and running.

Thanks Again.
