Overview

Driver Functions

MegaRAID provides drivers for the MegaRAID SAS RAID Storage
Adapters, which bring 3.0 Gbit/s Serial Attached SCSI and 3.0 Gbit/s
SATA II performance to host adapter, workstation, and server designs.
The controllers support internal and external storage devices, which
allows you to use a system that supports enterprise-class SAS and
desktop-class SATA II drives.

The SAS controllers integrate eight high-performance SAS/SATA II PHYs
and a PCI Express bus master DMA core. Each of the eight PHYs is
capable of 3.0 Gbit/s SAS link rates, and 3.0 Gbit/s SATA II link rates.

The SAS RAID controllers support the SAS protocol as described in the
Serial Attached SCSI Standard, version 1.1. The controllers also support
the Serial ATA II (SATA II) protocol defined by the Serial ATA
specification, version 1.0a. SATA II is an extension to SATA 1.0a.

The drivers do the following:

•

Support the PCI Express protocol

•

Support multiple RAID Storage Adapters (RSAs)

•

Provide the ability to see newly configured logical drives in the
configuration software utility without rebooting the system

•

Allow random deletion of logical drives created using the MegaRAID
Storage Manager (see the MegaRAID SAS Software User’s Guide
for more information)

•

Support use of the remaining array capacity by MegaRAID Storage
Manager

Driver Updates

Because LSI regularly updates device drivers, there might be a feature
added to your driver that is not included in the most recent manual
publication. If you have a question about a feature, consult the readme
file that accompanies the driver, or contact your MegaRAID support
representative. Be sure to use the latest Service Packs provided by the
operating system manufacturer.
