Overview: There are many changes in V6R1 from V5R4 and it will take time to fully comprehend and understand the implications of them all. Based on briefings and COMMON presentations from IBM, we’ve outlined some important points to consider if you’re considering implementing V6R1 for tape encryption.
IBM clearly understands that drive based encryption is not suitable for all users due to the complexity and costs associated with it. For more details, see our article 'LTO4 with Encryption – Why it might not be what you expect.' Due to the pressure that is now being put on organizations to secure all sensitive data, and particularly the requirements to meet PCI DSS, meant that IBM needed to look for other ways to help users meet their needs.
V6R1 is the first release of i5OS to offer built-in software tape encryption and many people have understandably held off from making a decision on how to encrypt their sensitive data being written to tape until the implications of V6R1 were known.
V6R1 also offers file level encryption on the disk storage and this may lead people to believe that this is the "total solution" they are looking for.
