two similar technologies on the same controller, within the same enclosure, and in the same virtual drive.
Note: LSI recommends that you carefully assess any decision to mix SAS drives and SATA drives within the same virtual drives. 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. As second-generation PCI Express RAID controllers, these controllers address the growing demand for increased data throughput and scalability requirements across midrange and enterprise-class server platforms. These controllers provide:
•6.0 Gb/s Serial Attached SCSI performance
•3.0 Gb/s SATA II performance
•Eight-lane, 5-Gb/s PCI Express host interface
The SAS 9260DE-8i RAID controller and the SAS 9280DE-8i RAID controller offer data security using disk encryption. This feature offers the ability to encrypt data on drives and use disk-based key management to provide data security. This solution provides data protection in the event of theft or loss of physical drives. With self-encrypting drives, if you remove a drive from its storage system or the server it is housed in, the data on that drive is encrypted and useless to anyone who attempts to access without the the appropriate security authorization.
For more information about self-encrypting drives, refer to the MegaRAID SAS Software User’s Guide.
The SAS 9260 RAID controllers, the SAS 9261 RAID controller, and the SAS 9280 RAID controllers use the LSI intelligent Battery Backup Unit 07 (LSIiBBU-07) to provide cached data protection and allow system builders to protect cached data even during the most catastrophic system failures.
Refer to the battery backup documentation on the MegaRAID Universal Software Suite CD for more information about this battery backup unit.
