Tri-Mode RAID Controller

Overview

Data center, cloud, and high-performance computing environments not
only require large amounts of storage capacity, but also must provide the
data protection, flexibility, and performance that today’s applications and
end users demand. The MegaRAID 9500 Series of 12Gb/s SAS/SATA/PCIe
(NVMe) Gen 4.0 Tri-Mode Storage Adapters, with 16 and 8 ports, address
these needs by delivering more performance and oering RAID data
protection for a range of high-end server storage applications.

Based on the Broadcom SAS3916 and SAS3908 eight-lane host PCIe to
SAS/SATA/PCIe RAID on Chip (RoC) controller, the 9500 series MegaRAID
adapters are the first RAID adapters to oer both PCIe Gen 4.0 host and
PCIe Gen 4.0 storage interfaces. PCIe Gen 4.0 enables these adapters for
high bandwidth by delivering twice the bandwidth and 75% more IOPs.

Applications

• High-port direct-attached connectivity applications

• Enterprise databases

• Analytics applications

• Medical imaging

• Media applications

• Flexible solutions for cloud computing

Tri-Mode SerDes Technology

Broadcom’s Tri-Mode SerDes technology enables operation of NVMe, SAS,
or SATA storage devices in a single drive bay. A single adapter can operate
in all three modes concurrently servicing NVMe, SAS, or SATA drives. The
adapter negotiates between speeds and protocols to seamlessly work
with any of the three types of storage devices. Tri-Mode support provides
a nondisruptive way to evolve existing data center infrastructure. By
upgrading to a Tri-Mode adapter, users can expand beyond SAS/SATA
and use NVMe without major changes to other system configurations. The
9500 series adapters are compatible with existing PCI Express SFF-8639
Module (U.2) backplanes, allowing users to boost performance for today’s
ever increasing bandwidth requirements.

Product Brief

As next-generation systems
expand the adoption of Tri-Mode
SerDes technology through
implementation of the SFF-TA-1001
and SFF-TA-1005 standards, the
9500 series adapters allow users
to get the most performance
and flexibility. The SFF-TA-1001
specification commonly known as
U.3 defines a common bay type
and connector for SAS (x1, x2,
x4), SATA, and NVMe (x1, x2, x4)
devices. The creation of the U.3
standard gives unprecedented
flexibility to system OEMs and data
centers that want to support the
latest storage technologies at the
lowest cost and system complexity.
With a single 9500 series adapter,
system implementers can take full
advantage of SAS, SATA, and x1, x2,
and x4 NVMe drives in a U.3 based
backplane.

Control and management of
multiprotocol (SAS/SATA/NVMe)
backplanes has been loosely
defined in previous generations
of products. Recognizing this,
Broadcom worked with key
industry members to introduce
Universal Backplane Management
(UBM) or SFF-TA-1005. UBM
builds upon current management
frameworks to provide a
comprehensive approach to
managing SAS, SATA, and NVMe.
The 9500 series adapters are
UBM ready, and customers can
immediately integrate these
adapters into their U.3 backplanes
utilizing UBM.

Hardware Secure Boot

The onboard controller
incorporates advanced security
through hardware secure boot.
The hardware secure boot feature
permits only authenticated
firmware to execute on the adapter.
The controller’s Internal Boot ROM
establishes an initial Root of Trust
(RoT). Hardware secure boot
authenticates and builds a Chain
of Trust (CoT) with succeeding
firmware images using the RoT,
meaning only authorized firmware
is executed on the adapter.
Broadcom provides the signed
firmware images, making the use of
hardware secure boot transparent
to customers, while providing
confidence in the security of the
solution.
