additional “header” information is written to beginning of tape. Memory  IBM LTO and 3592 tape cartridges contain a non-volatile memory chip / RFID transponder  Tape libraries can read / write RFID information  When tape is initialized the volume label and serial number are encoded to the memory chip, usage and performance stats are stored as well. Memory Chip / RFID 16kb memory built into every data cartridge. Contains tape identifier information, as well as performance and usage stats. IBM Tape Storage Media

IBM Storage Certification: IBM Storage Technical V2 (C1000-022) Module 4: IBM Tape Storage Last Update: October 2018 © 2018 International Business Machines  Encryption can mitigate risks associated with data security breaches, specifically tape data encryption  All current IBM tape drives (both LTO and 3592) support encryption Application Managed Encryption (AME)  Encryption is managed by the backup / archive application  Useful in operating environments that run an application already capable of generating and managing encryption policies and keys, such as Spectrum Protect  Application communicates with the tape drive directly passing the key(s) and commands L ibrary Managed Encryption (LME)  With LME, the tape library has a list of cartridge volume serial numbers that are designated for encryption  As a request is made for a cartridge on the encryption list the library tells the drive to encrypt / decrypt data on the cartridge  The drive itself make the request for the key from the key management software (eg. IBM SKLM) via the libraries IP interface with the key management system  Drive also requests a key tag to store on the cartridge for subsequent key identification IBM Tape Storage Encryption TS1155 TS4500
