6Gb/s SAS Performance Advantage 6Gb/s SAS is designed for backward compatibility with 3Gb/s SAS as well as with 6Gb/s and 3Gb/s SATA hard drives. Regardless of the drive speed, 6Gb/s MegaRAID controllers will deliver significant performance improvements in both read and write applications as compared to their 3Gb/s predecessors. Other new features of the 6Gb/s MegaRAID SATA+SAS controllers include greater signal integrity using Decision Feedback Equalization, support for more sophisticated SAS topologies using Expander Self-discovery/ Self-configuration, and additional safeguards to enhance data protection.

Superior Performance LSI SAS2108 ROC (RAID-on-chip) technology, PCI Express Generation 2x8 host interface and on-board 512MB 800MHz DDR2 cache memory enhance the performance of mainstream applications. Low-profile design makes it ideal for 1U and 2U servers hosting cloud, medical imaging or business critical applications and space-limited storage environments.
RAID Support The MegaRAID SAS 9260-4i supports data redundancy using SAS or SATA hard disk drives through RAID levels 0, 1, 5, 6, plus striping capability for spans (RAID levels 10, 50, and 60).
LSI SafeStore Encryption Services LSI is pleased to introduce SafeStore encryption services, which include instant secure erase for self-encrypting drives (SEDs). This techno-logy represents a significant step forward in securing a drive’s data from any unauthorized access or modification resulting from theft, loss, or repurposing of drives. Instant secure erase cryptographically erases an SED, whether it is 73GB or 1TB, in less than a second. This allows for secure drive returns or reuse.
Intuitive RAID Management Utility The MegaRAID Management Suite provides the essential software tools to efficiently manage MegaRAID products, whether deployed in an enterprise or small business. LSI offers a collection of applications and tools including a pre-boot setup utility and a full spectrum of online RAID management utilities. This suite of applications allow administrators to adjust SAS topology views from the system host, controller and disk enclosure down to the logical and physical drive level. Extending to enterprise deployments, these tools scale to easily configure, monitor and manage RAID volumes locally or over the LAN network.

The four-port MegaRAID® SAS 9260-4i controller provides a new level of performance and data protection for internal storage systems using up to 32 SATA or SAS hard drives or solid state drives. With data transfer rates of up to 6Gb/s per port, the MegaRAID SAS 9260-4i brings users new features and improved performance while continuing to support all the features of the previous 3Gb/s SATA and SAS generation. This value line controller, ideal for cost-sensitive 1U and 2U server applications, employs the latest in RAID-on-Chip technology and complies with the PCI Express® 2.0 specification for high-bandwidth applications.
