However, SAS 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 MegaRAID 6Gb/s SAS RAID Controllers User’s Guide Copyright © 2009 by LSI Corporation. All rights reserved. - Page 20 Although you can mix drives, LSI strongly discourages the practice. LSI offers a family of MegaRAID SAS RAID controllers addressing the needs for both internal and external solutions. The MegaRAID 6Gb/s SAS RAID controllers are based on the LSI first-to-market SAS IC technology and proven MegaRAID technology.

Page 21: Sas Controller Descriptions
SAS Controller Descriptions The 6Gb/s SAS RAID controllers are described as follows: • The MegaRAID SAS 9240-4i PCI Express 2.0 Low-Profile Serial-Attached SCSI/SATA II Disk Array Controller is a PCI-Express 2.0, half-size, full-height RAID controller based on the LSISAS2008 PCI Express-SAS/SATA I/O Processor chip. The MegaRAID SAS 9240-4i controls four internal 6-Gb/s SAS/SATA ports through one SFF-8087 x4 internal mini SAS connector. -
Page 22: General Description
SAS drives and desktop-class SATA II drives. Each MegaRAID 6Gb/s SAS RAID controller can connect to drives directly and can use expanders to connect to additional drives. Simplified cabling between devices is an additional benefit. Overview Copyright © 2009 by LSI Corporation. All rights reserved. - Page 23 Specification, Version 1.0a and the Serial ATAII; Extension to the Serial ATA Specification, Version 1.1. SATA II is an extension to SATA 1.0a.
