LTO-4 Encryption Available: Yes
Encryption Type: AES 256 bit hardware data encryption
Key Complexity: LTO-4 uses the Advanced Encryption Standard (AES) with the longest and most secure encryption key available at 256 bits. AES-256 is implemented within Galois Counter Mode (GCM). This is a method of increasing AES security by efficiently adding Message Authentication Codes to ensure the integrity of the backup data stored on tape. The HP LTO-4 Ultrium 1840 Tape Drive is designed to be compliant with the emerging standard for tape drive security, IEEE 1619.1.
Key Management: Encryption key managed via backup application or key management appliance.
Encryption Software Needed: The backup application needs to support hardware tape encryption.
WORM Media Compatible: Yes (LTO-4 WORM media)
Tape Backward Compatibility: Backward read compatible with LTO-2, -3. Read/Write compatible with LTO-3
System Interoperability: http://www.hp.com/go/connect
Vendor Comment: HP StorageWorks LTO-4 Ultrium 1840 Tape Drive is HP's first tape drive capable of storing up to 1.6 TB per cartridge while providing hardware-based encryption to enable greater levels of security and unprecedented performance.
Availability: Currently available
Base Cost: $4999 internal SCSI model

Product Snapshot #4
-----------------------------------------------------------------------------------------------------------
Product: Sun Microsystems Inc.; StorageTek T10000 Tape Drive
Buffer Size: Not provided
Storage Capacity: Capacity is 500 GB native
Data Transfer Rate: 120 MBps (uncompressed); up to 360 MBps with 3:1 compression)
Access Time: Average file access time (includes load/thread): 62 sec (28 sec for Sport Cartridge)
Tracks: 768 tracks
Interface: Fibre Channel or Native FICON connectivity
LTO-4 Encryption Available: Native with KMS - no, but available in 1H08; With TSM - yes today.
Encryption Type: AES-256 CCM, NIST approved per FIPS 140-2 Level 2
Key Complexity: Architected for 1 key per tape, changed as frequently as the customer would like. May also keep it as simple as a customer would prefer and use a single key for all tapes, drives, and time periods which seems to be the preference at this time.
Key Management: Keys are generated, stored, and managed from the Crypto Key Management Station (KMS) which is a FIPS 140-2 compliant appliance comprised of an Ultra 20 work station with Solaris 10 and the Sun SCA6000 crypto card. Keys are stored and transmitted using AES-256 CCM level encryption. KMS may be direct connected via secure network to a token in a token bay within a library to deliver keys via internal library network to drives. Alternatively, the KMS may be vaulted in secure storage (no network connection) with keys being downloaded into portable key token device and hand carried to a token bay within a library from which keys are delivered to drives. The second "air gap" scenario in which the KMS is secured as a stand-alone device with no connectivity and keys are carried via token constitutes the high security implementation which many federal agencies desire.
Encryption Software Needed: The software to support encryption is included within the KMS appliance.
WORM Media Compatible: Yes, T10000 data cartridges are WORM capable
Tape Backward Compatibility: Future generations of T10000 will read the existing T10000 media
System Interoperability: Sun StorageTek L180, L700e, L1400, SL8500 and PowderHorn 9310 libraries
Vendor Comment: Not provided
Availability: Currently available
Base Cost: List pricing for the T10000 tape drive is $37,000 for Fibre Channel in the SL8500 tape library; Current List price for the KMS is $35,000. List price for the encryption enablement key per enterprise drive is $5,000.
