6.2.2Locking SP

The Locking SP controls read/write access to the media and the cryptographic erase feature. Access to the Locking SP is available using the BandMasterX or EraseMaster passwords. Since the drive owner can define up to 16 data bands on the drive, each data band has its own password called BandMasterX where X is the number of the data band (0 through 15).

6.2.3Default password

When the drive is shipped from the factory, all passwords are set to the value of MSID. This 32-byte random value is printed on the drive label and it can be read by the host electronically over the I/O. After receipt of the drive, it is the responsibility of the owner to use the default MSID password as the authority to change all other passwords to unique owner-specified values.

6.3Random number generator (RNG)

The drive has a 32-byte hardware RNG that it is uses to derive encryption keys or, if requested to do so, to pro- vide random numbers to the host for system use, including using these numbers as Authentication Keys (pass- words) for the drive’s Admin and Locking SPs.

6.4Drive locking

In addition to changing the passwords, as described in Section 6.2.3, the owner should also set the data access controls for the individual bands.

The variable "LockOnReset" should be set to "PowerCycle" to ensure that the data bands will be locked if power is lost. This scenario occurs if the drive is removed from its cabinet. The drive will not honor any data read or write requests until the bands have been unlocked. This prevents the user data from being accessed without the appropriate credentials when the drive has been removed from its cabinet and installed in another system.

When the drive is shipped from the factory, the firmware download port is unlocked.

6.5Data bands

When shipped from the factory, the drive is configured with a single data band called Band 0 (also known as the Global Data Band) which comprises LBA 0 through LBA max. The host may allocate Band1 by specifying a start LBA and an LBA range. The real estate for this band is taken from the Global Band. An additional 14 Data Bands may be defined in a similar way (Band2 through Band15) but before these bands can be allocated LBA space, they must first be individually enabled using the EraseMaster password.

Data bands cannot overlap but they can be sequential with one band ending at LBA (x) and the next beginning at LBA (x+1).

Each data band has its own drive-generated encryption key and its own user-supplied password. The host may change the Encryption Key (see Section 6.6) or the password when required. The bands should be aligned to 4K LBA boundaries.

6.6Cryptographic erase

A significant feature of SEDs is the ability to perform a cryptographic erase. This involves the host telling the drive to change the data encryption key for a particular band. Once changed, the data is no longer recoverable since it was written with one key and will be read using a different key. Since the drive overwrites the old key with the new one, and keeps no history of key changes, the user data can never be recovered. This is tanta- mount to an instantaneous data erase and is very useful if the drive is to be scrapped or redispositioned.

ST33000650NS, SED FIPS 140-2 MODEL, ST33000651NS, ST33000652NS specifications

Seagate has long been a leader in data storage solutions, and their range of hard drives, specifically the ST33000652NS, ST33000651NS, SED FIPS 140-2 model, and ST33000650NS, showcases the company’s commitment to performance, security, and reliability. These models are ideal for enterprise applications requiring robust data protection and efficient storage capabilities.

The Seagate ST33000652NS is designed for high-capacity storage, offering 3 TB of space. It utilizes a SATA 6Gb/s interface which ensures rapid data transfer rates, making it suitable for environments that demand quick access to large datasets. Its 7200 RPM spindle speed enhances performance, ensuring that read and write operations are executed swiftly.

Similarly, the ST33000651NS also provides 3 TB of storage but is slightly optimized for different workloads. Both models feature Seagate’s advanced caching technology, which enhances performance by efficiently managing data flow to and from the drive. This is crucial for applications requiring high-throughput operations, such as video streaming and database management.

Transitioning to the Seagate SED FIPS 140-2 model, this drive is particularly focused on data security. The FIPS 140-2 certification indicates that it adheres to stringent federal standards for cryptographic modules, ensuring that sensitive information remains protected. This model caters to government and enterprise clients concerned about the integrity and confidentiality of their data.

On the other hand, the ST33000650NS also features a similar capacity but is geared towards reliability and endurance. It is engineered to endure the challenges of continuous operation, accommodating enterprise environments that require 24/7 accessibility without compromising performance.

All these models come with integrated power management features that enhance energy efficiency, reducing operational costs while minimizing environmental impact. They also utilize Seagate’s innovative technologies for error recovery and data integrity, ensuring users can rely on their performance under demanding circumstances.

In summary, the Seagate ST33000652NS, ST33000651NS, SED FIPS 140-2, and ST33000650NS collectively offer a diverse range of features catered for various enterprise needs. With a strong emphasis on storage capacity, data security, and performance reliability, these drives are well-equipped to handle the intensive demands of modern digital landscapes. Whether looking for high-speed access or enhanced security features, Seagate continues to deliver trustworthy solutions for today’s data-driven world.
