Next-Generation High Port SATA+SAS RAID
MegaRAID SATA+SAS controllers provide a new level of reliability, availability, and performance to
businesses that are facing storage challenges driven by unprecedented data growth. The MegaRAID
SAS 9280-24i4e, with twenty-four internal and four external ports, supports both internal drive
storage and external JBOD expansion for up to 240 SATA or SAS drives. With a large number of
internal ports, the 9280-24i4e connects up to 24 drives inside the server via direct connection or
passive backplane. Using the external SAS ports, multiple JBODs can be connected to a server,
providing a scalable and affordable solution for growing storage requirements.
6Gb/s SAS Performance Advantage
With data transfer rates of up to 6Gb/s per port, the MegaRAID SAS 9280-24i4e bring users new
features and improved performance, while continuing to support all the features of the previous
3Gb/s SATA+SAS generation. 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 are designed to deliver significant performance improvements in both read and write
applications as compared to their 3Gb/s predecessors.
