SAS3516 Tri-Mode ROC
PCIe to 16-port SAS/SATA/PCIe ROC
featuring Tri-Mode SerDes Technology
Broadcom Introduces High-Performance, 16-port
Tri-Mode SAS/SATA/ PCIe RAID-on-Chip (ROCs);
Ideal for Entry and Mid-Range Servers
Broadcom storage offers the industry’s broadest portfolio of storage
solutions, backed by decades of experience and trusted by the world’s
leading server and storage suppliers. Broadcom provides the building
blocks for storage solutions that help customers understand, prioritize,
store and protect critical data.
The 12 Gb/s SAS portfolio includes MegaRAID® controller cards, host
bus adapters (HBAs), advanced software options and SAS storage ICs,
including RAID-on-Chip (ROCs), I/O controllers and expanders.
Overview
The SAS3516 is the fifth generation of Serial Attached SCSI (SAS) RAID-
on-Chip (ROCs) based on the industry-leading Fusion-MPT (Message
Passing Technology) architecture. This next-generation ROC, which delivers
enhanced performance and power reductions over previous generations,
features Tri-Mode SerDes Technology that enables a seamless operation of
PCIe, SAS or SATA storage devices from any system design.
The SAS3516 host interface supports 8 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 backward compatible to 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.
The introduction of PCIe devices executing NVMe command sets to the
existing SAS/SATA infrastructure makes industry standard hot-pluggable
drive bays even more versatile. The 16-port Tri-Mode ROC device interface
provides SAS data transfer rates of 12, 6, and 3 Gb/s per lane, or SATA at 6
and 3 Gb/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 12 Gb/s speeds while
utilizing existing 6 Gb/s drives and backplanes.
