Good Day...  Here are the basic specs of vVNX; these were accurate a couple of months back.  I expect they are still valid.  You can have 16 Storage Objects (virtual equivalent to drives) Single SP Total System Memory  -  12 GB Supported Drive Type  -  vDisk Embedded IO Ports Per SP  -   2 x 1Gbe  Or  2 x 10Gbe No FC Connectivity is Available Backend Connectivity  -  vDisk Max Raw Capacity  -  4TB Max Pool LUN Size  -  4TB Max Pool LUNs Per System  -  64 Max Pools Per System  -  10   Hope this helps you.
1. Can we use vVNX for VBlock attachment ? if yes then how (i doubt) 2. Can we simulate all the storage classes with vVNX? 3. Can we use FC attachment"
