Robust RAID for SATA and SAS Hard Drives
The MegaRAID SAS 8708EM2, a second genera-
tion SAS/SATA RAID product from LSI, enables
users to create tiered storage with SATA and
SAS hard drives. Architected with a x8 PCI
Express host interface, 667MHz DDRII memory,
and the LSISAS1078 ROC controller, the MegaRAID
SAS 8708EM2 is the most powerful value-line
solution LSI has offered to date. With a true
MD2 low-profile form factor and two internal
Mini-SAS connectors, this adapter allows
system builders to attach up to 32 SAS and/or
SATA drives in high-density servers and systems
for maximum design flexibility.

RAID 6 for Advanced Data Protection
The MegaRAID SAS 8708EM2 supports all
key RAID levels including RAID 6 and 60 for
increased fault tolerance. RAID 6 tolerates two
simultaneous drive failures, and thus the ability
to manage unrecoverable media errors during
re-builds. This is particularly useful when using
a lot of high-capacity SATA disk drives.

Intuitive RAID Management Utility
The MegaRAID Management Suite™ provides
the essential software tools to efficiently man-
age MegaRAID products, whether deployed
in an enterprise or small business. LSI offers a
collection of applications and tools including
a pre-boot setup utility and a full spectrum of
online RAID management utilities. This new
suite of applications allow administrators to
adjust SAS topology views from the system
host, controller and disk enclosure down to
the logical and physical drive level. Extending
to enterprise deployments, these tools scale
to easily configure, monitor and manage RAID
volumes locally or over the LAN network.

Intelligent Battery Backup Support
The MegaRAID LSIiBBU06 is a battery-backup
module that protects the integrity of the cached
data on a MegaRAID controller in the event of a
complete power or server failure. This add-on
module, which connects directly to the adapter,
has the added functionality to automatically
charge the battery pack and communicate with
the host system the battery status, such as voltage,
temperature, and capacity.
