The ServeRAID-MR10is controller is based on the MegaRAID
first-to-market SAS IC technology and proven technology. As the
second-generation PCI Express storage adapter, the 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 and external solutions.
SAS technology brings a wealth of options and flexibility with the use of
SAS devices and SATA II devices within the same storage infrastructure.
However, SAS devices and SATA devices bring individual characteristics
that make each one a more suitable choice depending on your storage
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 innovative intelligent Battery Backup Unit (iBBU) is pre-installed on
the ServeRAID-MR10is 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. For more
information about charging the battery, see
"Installing the Intelligent Battery Backup Unit
The ServeRAID-MR10is controller supports the SAS protocol as
described in the Serial Attached SCSI Standard, version 1.1. The
controller 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-MR10is controller is a versatile
controller that provides the backbone of both server and high-end
workstation environments.
Each port on the ServeRAID-MR10is 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
