xPreface
Protecting against Electrostatic Discharge – Static electricity can
harm delicate components inside your computer. To prevent static
damage, discharge static electricity from your body before you touch any
of your computer’s electronic components, such as the microprocessor.
You can do so by touching an unpainted metal surface, such as the metal
around the card-slot openings at the back of the computer.
As you continue to work inside the computer, periodically touch an
unpainted metal surface to remove any static charge your body may
have accumulated. In addition to the preceding precautions, you can also
take the following steps to prevent damage from electrostatic discharge:
•When unpacking a static-sensitive component from its shipping
carton, do not remove the component from the antistatic packing
material until you are ready to install the component in your
computer. Just before unwrapping the antistatic packaging, be sure
to discharge static electricity from your body.
•When transporting a sensitive component, first place it in an
antistatic container or packaging.
•Handle all sensitive components in a static-safe area. If possible, use
antistatic floor pads and workbench pads.

1.1 Overview
The ServeRAID M1115 Serial Attached SCSI (SAS)/Serial ATA (SATA)
controller is a high-performance intelligent PCI Express-to-SAS/SATA
controller with RAID control capabilities. This controller provides
reliability, high performance, and fault-tolerant disk subsystem
management.
The ServeRAID-M1115 controller is a versatile controller that provides
the backbone of both server and high-end workstation environments. It
is an ideal RAID solution for the storage of workgroup, departmental, and

1-2 Overview
enterprise systems, and offers a cost-effective way to implement RAID in
a server.
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.
Note: You cannot mix SAS drives and SATA drives within the
same virtual disk(s).
The ServeRAID-M1115 controller is based on the MegaRAID
first-to-market SAS IC technology and proven technology. As a
second-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 controllers to address the needs for both internal solutions
and external solutions.The controller supports the SAS protocol as
described in the Serial Attached SCSI Standard, version 3.0.
In addition, the controller supports the Serial ATA II (SATA II) and SATA
III protocols. The SATA III protocol is 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.
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, which enables communication with other SATA 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 device through an attached expander
