Chapter 1

Overview

This chapter provides a general overview of the ServeRAID M5120

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”

• Section 1.5, “Benefits of the SAS Interface”

• Section 1.6, “Benefits of the ServeRAID M5120 SAS/SATA

Controller”

• Section 1.7, “Hardware Specifications”

• Section 1.8, “Technical Support”

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
