MegaRAID® 9400
Series Tri-Mode
Storage Adapters

12Gb/s SAS/SATA/NVMe
Tri-Mode PCIe RAID Controllers

Industry’s First Hardware RAID adapter with
Tri-Mode SerDes Technology

Broadcom enables high performance storage connectivity and flexible system
designs that support any combination of NVMe, SAS and SATA devices
with the industry’s first hardware RAID adapter with Tri-Mode SerDes. The
MegaRAID 9400 series of adapters expands on the industry-leading family of
12Gb/s storage adapters from Broadcom with 8 and 16 port internal, external
and combination Tri-Mode port options.

NVMe Performance Gains for Storage

The MegaRAID Tri-Mode storage adapters bring NVMe performance benefits
to the storage tier by providing connectivity and data protection that
MegaRAID technology has oered for over 20 years for SAS/SATA interfaces.
Based on the dual-core SAS3516 or SAS3508 RAID on Chip (ROC) and
72-bit DDR4-2133 SDRAM, these controllers provide bandwidth and IOPS
performance increases compared to the previous generation and are ideal
for high-end servers utilizing internal storage or connecting to large-scale
external storage enclosures.

Product Brief

Endless design flexibility using Tri-Mode Controllers

Broadcom’s Tri-Mode SerDes Technology enables operation of NVMe,
SAS, or SATA storage devices in a single drive bay. A single controller can
operate in all three modes concurrently servicing NVMe, SAS, or SATA
drives. The controller negotiates between the speeds and protocols to
seamlessly work with any of the three types of storage devices. Tri-Mode
support provides a non-disruptive way to evolve existing data center
infrastructure. By upgrading to a Tri-Mode controller, users can expand
beyond SAS/SATA and use NVMe without major changes to other system
configurations.
