Next-Generation SATA+SAS RAID for
External Enclosures
Today’s newest external enclosure designs
are based on architectures that support both
SATA and SAS drives. The MegaRAID SAS
9280-8e and 9280DE-8e, with eight external
SATA+SAS ports, are ideal for conguring these
external enclosures with your choice of high-
performance SAS hard drives, high-capacity
SATA hard drives or power-saving solid state
drives (SSDs). With data transfer rates of up to
6Gb/s per port, the MegaRAID SAS 9280-8e
and 9280DE-8e bring users new features and
improved performance, while continuing to
support all the features of the previous 3Gb/s
SATA+SAS generation. These feature line
controllers employ the latest in RAID-on-
Chip technology, comply with the PCI
Express 2.0 specification and provide
additional data security using LSI™ SafeStore
encryption services.
6Gb/s SAS Performance Advantage
6Gb/s SAS is designed for backward compati-
bility with 3Gb/s SAS as well as with 6Gb/s
and 3Gb/s SATA hard drives. Regardless of
the drive speed, 6Gb/s MegaRAID controllers
will deliver signicant performance improve-
ments in both read and write applications
as compared to their 3Gb/s predecessors.
Other new features to the 6Gb/s MegaRAID
SATA+SAS controllers include greater
signal integrity using Decision Feedback
Equalization, support for more sophisticated
SAS topologies using Expander Self-discovery/
Self-conguration, and additional safeguards
to enhance data protection.
LSI SafeStore Encryption Services
LSI is pleased to oer SafeStore encryption
services, which oer instant secure erase and lo-
cal key management* for self-encrypting drives
(SEDs). This technology represents a signicant
step forward in securing a drive’s data from any
unauthorized access or modication result-
ing from theft, loss, or repurposing of drives.
Instant secure erase cryptographically erases
an SED, whether it is 73GB or 1TB, in less than a
second. This allows for secure drive returns or
reuse. SafeStore local key management provides
the necessary management and protection of
SEDs using a simple pass phrase, security key
identier, and security key le, which can be set
and applied to all SEDs assigned to a MegaRAID
adapter. This removes the complexity of
managing each SED’s unique encryption key,
and essentially relieves the administrator from
most of the daily tasks of securing data.
