SED features include:

• Drive-level AES 256 encryption
• Safeguard against costly security breaches and exposure of proprietary data if a

hard drive is stolen or lost

• Rich security options to help ensure compliance with data security, information

disclosure, and privacy regulations for data at rest

• Ability to securely erase data for disk disposition, redeployment, or service calls
• Encryption functionality (supported when used in conjunction with supported

ServeRAID controllers and optional Advance Feature Keys)

• MegaRAID Management Suite (MSM), which offers a quick and simple

configuration path to disk encryption and also assists with local key management

• Compatibility with Security Key Lifecycle Manager (SKLM) for System x, which

offers centralized, automated, and simple encryption key management of SEDs in

local and distributed System x environments

As the newest additions to the IBM System x family of 2.5-inch SAS HDDs, hybrids,

and SAS SEDs, the 10,000 rpm and 15,000 rpm 12 Gbps and 6 Gbps 2.5-inch hot-

swap and simple-swap drives offer the high-density and high-performance drive

options providing a broad selection of choices to satisfy a wide range of applications.

The drives are 512 emulation (512e) a new drive format technology to increase

drive capacity while maintaining data integrity. These new drives are positioned at

the top of the IBM SAS HDD line.

The new 10,000 rpm and 15,000 rpm 12 Gbps and 6 Gbps SAS drives are offered in

a 2.5-inch form factor. The SAS HDDs and hybrid drives are available as hot-swap

and simple-swap versions. The SAS SEDs are available only as hot-swap versions.

The hybrid drives combine a cache of NAND flash and conventional media to

accelerate hard disk drive performance, enabling higher I/O performance while

leveraging the capacity and cost of spinning media for primary storage.

The SED is designed to reduce the vulnerability of data at rest to potentially costly

exposures of proprietary data resulting from hard drives being stolen, misplaced, or

improperly disposed.

Key features and benefits include:

• Increased bandwidth. 12 Gbps SAS HDD, SED, and hybrids support 12 Gbps link

rates.

• Higher density. 512e SAS drives meet client requirements for larger capacities in

a 2.5-inch form factor - up to 1.8 TB.

• RoHS compliance. 10,000 and 15,000 rpm 2.5-inch SAS HDD/SED drives are

RoHS compliant.

• Reliability. Outstanding reliability enables operation in RAID environments

without compromising application performance or availability.

• Security. The self-encrypting drives (SEDs) include drive-level AES 256

encryption. These drives are compatible with Security Key Lifecycle Manager

(SKLM) for System x, which offers centralized, automated, and simple encryption

key management of SEDs in local and distributed System x environments.

• Increased performance. The hybrid drives incorporate a cache of NAND flash to

promote "hot data" and accelerate hard disk drive performance.

You can increase your storage and data management effectiveness when you install

these new high-density SAS drives in your IBM System x configurations.

Performance characteristics for the 300 GB, 600 GB, 900 GB, 1.2 TB, and 1.8 TB

drives include:

• Formatted capacity of 300,000 MB through 1,800,000 MB.
