ALMS is required if you use the new high density frames.  These can provide
three times the tape density as the normal frames.  ALMS is needed to
automatically manage which tapes are located in which slots, keeping the
most frequently used tapes in the most readily accessible physical
slots.  Another advantage of the virtualization that ALMS provides.

TS3500 libraries do not require ALMS for LTO encryption as long as there
are no non-encryption-capable LTO drives mixed in.

As I understand it, ALMS IS required if you implement Encryption
for LTO4 tapes/drives on a 3584 library, is that true?
