needs. MegaRAID

gives you the flexibility to combine these two similar
technologies on the same controller and within the same enclosure.
Note:
You cannot mix SAS drives and SATA drives within the
same
virtual disk(s)
.
The ServeRAID-MR10M controller is based on the MegaRAID
first-to-market SAS IC technology and proven technology. As the
second-generation PCI Express controller, the ServeRAID-MR10M
controller addresses the growing demand for increased data throughput
and scalability requirements across midrange and enterprise-class server
platforms. IBM offers a family of SAS controllers to address the needs
for both internal solutions and external solutions.
The innovative intelligent Battery Backup Unit (iBBU) is pre-installed on
the ServeRAID-MR10M controller. The iBBU 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. See
“Introduction to the Intelligent Battery Backup Unit,”
for
more information about the intelligent battery backup unit.
The controller supports the SAS protocol as described in the
Serial
Attached SCSI Standard
,
version 1.1
. It also supports the Serial ATA II
(SATA II) protocol defined by the
Serial ATA Specification, Version 1.0a
,
and the
Serial ATAII; Extension to the Serial ATA Specification, Version
1.1
. SATA II is an extension to SATA 1.0a. The ServeRAID-MR10M
controller is a versatile controller that provides the backbone of both
server and high-end workstation environments.
Each port on the ServeRAID-MR10M controller supports SAS devices
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
