PowerEdge 2950 with PERC6I-INT Maximum capacity?

Hi, I've been looking everywhere for this! 

I need to know what is the maximum disk capacity (size) that can be used with a PERC6I-INT RAID in a PowerEdge 2950 server. 

I am considering in buying 6Tb SATA drives for my server, but I'm not sure if the hardware can deal with 6 drives at 6Tb.
