Thanks fot letting us know. This was put in an area on Powerlink which had some user restrictions. We are working on getting that fixed. Please check again in a couple of days.  For the time being, you can access the tool at this FTP site: ftp://ftp.emc.com/outgoing/VNX_VNXe_Capacity_Calculator_3.0/VNX_VNXe_Capacity_Calculator_3.0.exe
Does anyone has a link to VNXe sizing calculator which shows useable capacities on various RAID group combinations?
