SAS/SATA controller, which has RAID control capabilities. It consists of
the following sections:
• Section 1.1, “Overview”
• Section 1.2, “ServeRAID M5120 Controller Descriptions and
Limitations”
• Section 1.3, “General Description”
• Section 1.4, “Configuration Scenarios”

1.1 Overview
The ServeRAID M5120 Serial Attached SCSI (SAS)/Serial ATA (SATA)
controller is a high-performance intelligent PCI Express-to-SAS/SATA III
controller with RAID control capabilities. This controller provides
reliability, high performance, and fault-tolerant disk subsystem
management.
The ServeRAID M5120 SAS/SATA controller is a versatile controller that
provides the backbone of server environments. It is an ideal RAID
solution for the storage of workgroup, departmental, and enterprise
systems. This controller offers a cost-effective way to implement RAID in
a server.
1-2 Overview
Note: You cannot mix SAS drives and SATA drives within the
same virtual disk(s).
The ServeRAID-M5120 controller is based on the MegaRAID
first-to-market SAS IC technology and proven technology. As a
third-generation PCI Express controller, it addresses the growing
demand for increased data throughput and scalability requirements
across midrange and enterprise-class server platforms. Lenovo offers a
family of SAS controller to address the needs for both internal solutions
and external solutions.
SAS technology brings a wealth of options and flexibility with the use of
SAS devices and SATA 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.
The controller supports the SAS protocol as described in the Serial
Attached SCSI Standard, version 3.0. It also supports the Serial ATA III
(SATA III) protocol defined by the Serial ATA Revision 3.0, and the
Serial ATA III; Extension to the Serial ATA Specification, Version 2.0.
SATA III is an extension to SATA 2.0. The ServeRAID-M5120 controller
is a versatile controller that provides the backbone of both server and
high-end workstation environments.
Each port on the controller supports SAS devices and/or SATA devices
using the following:
• SAS Serial SCSI Protocol (SSP), which enables communication with
other SAS devices
• SATA III, which enables communication with other SATA III 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 III device through an attached expander
