Tape Drive

Use of the RJ45 maintenance port on a non-encrypiton drive is restricted to Sun service
personnel only.
Note – Customer attachment to the maintenance port of a non-encrypiton drive has
caused problems. Sun neither supports nor assumes any responsibility for
unauthorized use of the maintenance port by non-Sun personnel.
Encryption
Encryption is based on the science of cryptography and is one of today’s most effective
ways to achieve data security. To read an encrypted file, you must have access to the
key that enables the drive to decipher the data.
The T9840D tape drive employs a device-based (or data-at-rest) encryption solution.
The drive is shipped from the factory encryption-capable, but not encryption-enabled.
You must explicitly enable the drive for encryption.
Note – A tape drive that has not been enabled for encryption can neither read nor
append to any encrypted data cartridge.
An encryption-enabled drive can:
■
Write to the data cartridge in encrypted mode only (by using its assigned write key)
■
Read an encrypted data cartridge, if it has the proper read key
■
Read non-encrypted data cartridges
■
Format tape cartridges
An encryption-enabled drive cannot:
■
Append (write) to a non-encrypted data cartridge
■
Mix encrypted and non-encrypted data on the same cartridge
