The MegaRAID 8480 Storage Adapter is based on the LSI first-to-market
SAS IC technology and proven MegaRAID technology. As the
second-generation PCI Express storage adapter, the MegaRAID 8480
controller addresses the growing demand for increased data throughput
and scalability requirements across midrange and enterprise-class
server platforms. LSI offers a family of MegaRAID SAS adapters
addressing the needs for both internal and external solutions.
The innovative LSI intelligent Transportable Battery Backup Unit 2
(LSIiTBBU02) is pre-installed on the MegaRAID 8480 RAID Controller.
The LSIiTBBU02 provides cached data protection, which allows system
builders to protect cached data even during the most catastrophic system
failures.
Note:
You must charge the battery before use. Refer to the
MegaRAID Battery Backup Unit User’s Guide
on the
MegaRAID 8480
CD for more information.
The MegaRAID 8480 RAID controller supports the ANSI
Serial Attached
SCSI standard, version 1.1
. In addition, the controller supports the SATA
II protocol defined by the
Serial ATA specification, version 1.0a
.
Supporting both the SAS and SATA II interfaces, the controller is a
versatile controller that provides the backbone of both server and high-
end workstation environments.
Each port on the MegaRAID 8480 RAID controller supports SAS and/or
SATA II devices using the following:
• SAS Serial SCSI Protocol (SSP), which enables communication with
other SAS devices
• SATA II, which enables communication with other SATA II devices
• Serial Management Protocol (SMP), which communicates
topology management information directly with an attached SAS
expander device
• Serial Tunneling Protocol (STP), which enables communication with
a SATA II device through an attached expander
