Overview
The SA3616W is the seventh generation of Serial Attached SCSI (SAS)
controllers based on the industry-leading Fusion-MPT (Message
PassingTechnology) architecture. The SAS3616W host interface supports
16 PCI Express® (PCIe) lanes and complies with the PCIe 3.1 specification
that extends the PCIe data rates up to 8.0 GT/s per lane, and is backwards
compatible to the 5.0/2.5 GT/s. It also incorporates End-to-End CRC
(ECRC) with Advanced Error Reporting (AER) in lane and polarity reversal,
power management, hot plug support, and MSI/ MSI-X and legacy interrupt
generation.

Broadcom Tri-Mode SerDes Technology enables seamless operation of
PCIe, SAS, or SATA storage devices in a single drive bay. The introduction
of PCIe devices executing NVMe to the existing SAS/SATA infrastructure
makes industry standard hot-pluggable drive bays even more versatile.
The sixteen-port Tri-Mode device interface provides SAS data transfer
rates of 12, 6, and 3Gb/s per lane, or SATA at 6 and 3Gb/s data transfer
rates per lane, or PCIe data transfer rates of 8, 5, and 2.5 Gb/s. The device
automatically negotiates between the speeds and protocols. T-10 Data
Protection Model (T-10 End to End Data Protection (EEDP) for early
detection of and recovery from data corruption, and Spread Spectrum
Clocking (SSC) for EMI reduction are supported. Additional features include
SAS 2.1 power management and DataBolt Technology allowing users to
take advantage of 12Gb/s speeds while utilizing existing 6Gb/s drives and
backplanes.
The SAS3616W supports up to 16 direct attached PCIe devices and
complies with PCIe 3.1 specifications. The device supports PCIe Dynamic
Power allocation (DPA), ECRC, and AER with compatible devices.
The SAS3616W is ideal for the host or drive side connect for external
storage controllers requiring a SAS/SATA interface. The SAS3616W can
support up to 2,000 SAS or SATA devices and 8,000 outstanding IOs
without external RAM and can achieve over 1 million IOs per second.
Broadcom provides a complete suite of industry standard operating system
drivers. Broadcom also supports Virtual Operating Systems with device
emulation and para-virtualization.
