Forgot to include this link from IBM regarding their EKM support. http://www-01.ibm.com/support/docview.wss?uid=ssg1S4000504
----- Original Message ----- Wanda, As always, thanks for the detailed explanation. However, it brings up lots of questions. >>> With externally-managed encryption, the keys are managed by the EKM. Since this would be hardware-based and encrypts everything, this is the way we would go. >>> You set the encryption mode on the library to library-managed. The EKM has to be run on a server. It is a pay-for product. Huh? I downloaded EKM from the IBM FTP sight. It is Java based and nobody ever said anything about paying for it? As I understand it, in this scenario with our 3494 (soon to be replace with a TS3500/3584), the "EKM server" has to talk to the tape library to get the keys from it (DRIVEE=ALLOW). When Googling, one doc/comment we saw the person simply installed it on the TSM server. My question, since I am running 7-servers, do I need multiple instance - one per TSM server or just one and it gets everything from the 3494? I am confused...... >>> High learning curve. Lots of testing required to make sure you can recover. Agreed. We are still digging through the docs on just installing and implementing EKM and who connects to who and where...... >>> You have to be careful about protecting the EKM; you have to recover the EKM at a DR site before you can read your tapes. (If you have a hot site, better to share the keys between the libraries.) More like a "lukewarm sight" - I have an offsite vault/TSM server where the tapes are stored and daily each production TSM server does a DB backup to the offsite TSM server. >>> But with the EKM, your security group can control the key management, certificate changing, etc. And then DB backup tapes, EXPORT, and BACKUPSET tapes can be encrypted. This totally throws me off - I really need a "paint by numbers" diagram on how all the pieces connect - I have never dealt with encryption.....
