PM8032 Tachyon QE8www.DataSheet4U.com
Quad-Channel 8 Gbps Fibre Channel Controller
PRODUCT OVERVIEW
The PM8032 Tachyon QE8 device is a high-performance 4-port 8 Gbps
Fibre Channel controller. It features an 8-lane native PCI-Express Gen-II
link, enabling full-duplex operation simultaneously on all ports. The
Tachyon QE8 is an integrated single chip solution ideal for a variety of
high-performance I/O applications.
The proven Tachyon State-Machine architecture scales directly with
system CPU performance and is not limited by the constraints of an
embedded microprocessor. The Tachyon QE8 supports up to 4
processors per FC link using 4 independent register and API queue
structures. This feature allows systems to scale to required perfor-
mance as necessary while maintaining compatibility with the Tachyon
programming model at the register level, and with the Tachyon
Software Development Kit (TSDK) API tools.
The Tachyon QE8 supports the Protection Information model as
described in the SCSI Block Commands - 2 (SBC-2) Standard, which
incorporates a Data Integrity Field (DIF) in data records. Additionally,
the QE8 has masking capabilities for enhanced functionality. T10 DIF
provides robust CRC-based data protection with mechanisms to
initiate, extend, verify and replace, or terminate a protection domain.
The Tachyon QE8 offers additional performance by providing Multi-DMA
and advanced frame-handling functions that are normally handled by
the host processor. These enhancements make it possible for the
system to utilize intelligent frame handling while reducing CPU utili-
zation, memory controller utilization, and PCI-Express utilization.
