2.0 Scope

This manual describes Seagate Technology® LLC, Savvio® 15K.2 SAS (Serial Attached SCSI) disc drives.

Savvio drives support the SAS Protocol specifications to the extent described in this manual. The SAS Inter-

face Manual (part number 100293071) describes the general SAS characteristics of this and other Seagate

SAS drives. The Self-Encrypting Drive Reference Manual, part number 100515636, describes the interface,

general operation, and security features available on Self-Encrypting Drive models.

Note. Previous generations of Seagate Self-Encrypting Drive models were called Full Disk Encryption

(FDE) models before a differentiation between drive-based encryption and other forms of encryp-

tion was necessary.

Product data communicated in this manual is specific only to the model numbers listed in this manual. The data

listed in this manual may not be predictive of future generation specifications or requirements. If you are

designing a system which will use one of the models listed or future generation products and need further

assistance, please contact your Field Applications Engineer (FAE) or our global support services group as

shown in Section 1.0.

Unless otherwise stated, the information in this manual applies to standard and Self-Encrypting Drive models.

For more information on FIPS 140-2 Level 2 certification see Section 8.0 on page 35.
