16-port 12Gb/s SAS/SATA IO Controller (IOC)
Avago Technologies products serve four primary target markets: wireless communications, wired
infrastructure, enterprise storage, and industrial. Avago o ers the industry’s broadest portfolio of
storage solutions, backed by decades of experience and trusted by the world’s leading server and
storage suppliers. Avago provides the building blocks for storage solutions that help customers
understand, prioritize, store and protect critical data.
The Avago 12Gb/s SAS portfolio includes MegaRAID^® controller cards, host bus adapters (HBAs),
advanced software options, Syncro^® shared DAS solutions and SAS storage ICs, including RAID-on-
Chip (ROCs), I/O controllers and expanders.
Overview
The SAS 3216 is a fourth generation Serial Attached SCSI (SAS) IO Controller (IOC) device based on
the leading Fusion-MPT^™ (Message Passing Technology) architecture. The SAS 3216 integrates the
latest enhancements in SAS and PCI Express technology.
The SAS 3216 supports 8 PCIe^® lanes and complies with the PCI Express (PCIe) 3.0 speci cation 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 data rate supported by PCIe 2.x., 1.x. It also incorporates enhancements such as End-to-End
CRC (ECRC) with Advanced Error Reporting (AER) and the latest advancements in lane and polarity
reversal, power management, hot plug support, and MSI/MSI-X and legacy interrupt generation.
The sixteen-port IO controller device provides SAS data transfer rates of 12, 6, and 3Gb/s per lane
and SATA data transfer rates of 6 and 3 Gb/s per lane. The device automatically negotiates between
the speeds. Enhanced features are supported such as T-10 EEDP for early detection of and recovery
from data corruption and Spread Spectrum-Clocking (SSC) for EMI reduction. Additional features
include DataBolt^™ Technology, allowing users to take advantage of 12Gb/s speeds while utilizing
existing 6Gb/s drives and backplanes, and SATA FIS-based switching that provides improved
performance with SATA drives.
The SAS 3216 is ideal for the host or drive side connect for external storage controllers requiring
a SAS/SATA interface. The SAS 3216 can support up to 2,000 devices and 8,000 outstanding IOs
without external RAM and can achieve up to 1 million plus IOs per second.
Avago provides a complete suite of industry standard operating system drivers. Avago also supports
Virtual Operating Systems with device emulation and para-virtualization.
Fusion-MPT Architecture Overview
Fusion-MPT architecture marks the next generation of I/O architecture designed to deliver the
highest performance available today while reducing time to market, integration, and certi cation
time. Fusion-MPT devices are high performance, cost-e ective protocol controllers that represent
the newest system- level integration technology in intelligent I/O processors from Avago.
