1.1.1Driver 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 software (see the MegaRAID SAS Software User’s Guide for more information)

Support use of the remaining array capacity by MegaRAID software.

1.1.2Driver Updates

Because LSI Logic 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.
