Overview : SATA II and III Features

SATA II and III Features

The SATA bus is a high-speed, internal bus that provides a low pin count (LPC), low voltage level bus for device connections between a host controller and a SATA device.

The following list describes the SATA II and III features of the Nytro MegaRAID controllers:

*

Supports SATA II and III data transfers of 6Gbs

*

Supports Serial Tunneling Protocol data transfers of 6Gbs

*

Provides a serial, point-to-point storage interface

*

Simplifies cabling between devices

*

Eliminates the master-slave construction used in parallel ATA

*

Lets the addressing of multiple SATA II and III targets through an expander

*

Allows multiple initiators to address a single target (in a fail-over configuration) through an expander

NOTE  You must carefully assess any decision to mix SAS drives and SATA drives within the same virtual drive (VD). Although you can mix drives, this practice is strongly discouraged, because the drives have different performance and reliability characteristics.
