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
Overview
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.
