Lun Encryption on VNX

Hello and thank you in advance for any assistance provided!

Our team has recently deployed a VNX5300 solution and for the most part, everything has went smoothly. A client of ours requires that their data be encrypted at rest and after thorough discussions with EMC sales, it was determined that the VNX Security and Compliance Suite was the product we required to encrypt VNX Luns. Unfortunately, this product has been a nightmare so far as all that was included in this Suite was VNX Event Enabler which after researching, is nothing more than Antivirus software for the VNX. I am hoping that someone in the community has experience with encrypting from the VNX level rather than using tools such as LUKS for Linux or Bitlocker for Windows. Is the Security and Compliance Suite what is required and if so, is there Installation Documentation anywhere? I've done a lot of research and have yet to find anything other than Event Enabler documentation. Thank you again!
