PMC
Enters RAID Processor Market
Last week, PMC-Sierra entered the crowded market for RAID
processors. The company is coming in from the top with
the industry’s
first RAID processor (also known as RAID-on-chip or RoC) featuring
6Gbps SAS/SATA interfaces, double the rate of today’s
mainstream SAS/SATA ports. The PM8010 “maxSAS SRC 8x6G” is
also the first RAID controller to integrate PCI Express 2.0
interfaces. Backward compatible with first-generation PCIe,
PCIe 2.0 provides twice the data rate per lane.
The
processor is organized into four subsystems: CPU complex,
SAS/SATA controller, RAID engine, and PCI/memory interface
controller with DMA engines. Connecting them is a nonblocking
switch fabric. Operating at 600MHz, the CPU complex contains
three scalar, multithreaded MIPS 34K cores.Two of the CPUs
accelerate fundamental RAID functions, exporting these capabilities
through an API to the RAID application stack running on the
third CPU. Multithreading is a good fit, but a new approach,
for the inherently I/O-centric processing task posed by RAID.
The use of three CPUs provides more aggregate CPU power than
offered by the single-core superscalar PowerPC-based RAID
processors from LSI and AMCC. Intel’s IOP348, with
its pair of 1.2GHz XScale CPUs, has more aggregate CPU performance,
but one CPU is reserved for SAS/SATA protocol processing.
The SRC 8x6G therefore provides more CPU cycles for application
processing.
Supporting DDR2-800,
the SRC 8x6G operates its DRAM interface a notch faster than
the DDR2-667 supported by the LSI SAS1078
and two grades faster than Intel’s IOP348. The prodigious
2MB of on-chip memory of the PMC-Sierra processor may
alleviate use of the memory interface, as well as eliminate
external memory in cost-optimized systems.
Software
is a critical issue for any processor, both in terms of extracting
performance
and for gaining market acceptance.
PMC-Sierra has landed Hewlett-Packard as a lead customer, and
HP will port its proprietary stack. While, the HP win is a
key victory in LSI’s territory, further gains at server
OEMs will require third-party software support. The SRC 8x6G
provides important new hardware capabilities, which are likely
to attract software suppliers. With these capabilities and
the HP win, PMC-Sierra has instantly become a serious supplier
of RAID processors. —Joe

Broadcom
Leads in Market Share
According to data gathered by The Linley Group, the networking
silicon market grew 15% in 2006. Broadcom again was the top-ranked
supplier of wired-communications ASSPs, growing at more than
twice the rate of the overall industry and becoming bigger
than its three largest competitors combined. Texas Instruments
grew even faster than Broadcom, as success in cable modems
offset share loss in DSL. Several companies grew through
acquisition. Startup Cortina tripled in size by buying
several product lines
from Intel. PMC-Sierra bought into broadband by acquiring
PON leader Passave, and Ikanos complemented its VDSL
offering with
ADSL chips and processors from Analog Devices.
Accounting for nearly one-third of all wired communications
ASSPs, sales of Ethernet components grew 14%. Most of the
gains came from Gigabit Ethernet, which grew 24%. Shipments
of 10
Gigabit Ethernet NICs more than doubled, and Neterion extended
its lead in this market. Broadband ICs accounted for almost
one-fourth of all sales and grew 20%. Sales of DSL and
cable modem ICs were strong. PON IC sales grew with
the overall
broadband market, a lackluster performance for an emerging
category.
Industry revenue from network processors topped $200 million,
surging 34% for the year. Intel catapulted to the top
of the rankings, displacing AMCC from position it has
held
since pioneering
the NPU category a decade ago. Agere (now LSI), Bay Microsystems,
EZchip Technologies, and Wintegra all handily outpaced
the industry’s growth rate.
Complementary to networking silicon, high-end embedded
and communications processors increased sales about
10%, with
AMCC being one of the fastest growing suppliers. In
wireless, baseband
processors for handsets grew 15% as a surge in handset
shipments was offset slightly by falling prices. Growth
in smartphones
and 3G handsets propelled application-processor revenue
up 23%, with first-ranked TI growing even faster. This
gain
compensated somewhat for TI’s loss of baseband share to Qualcomm
and MediaTek. —Joe

Tech Announces Program for Enterprise and Data Center Networking
Seminar
Join us on July 18 for a Linley Tech seminar on the technologies
driving the future of enterprise and data-center networks. Bob
Wheeler, senior analyst with The Linley Group, will kick off
the program with an overview of market, technology, equipment-design,
and silicon trends for designers of enterprise and data-center
networking equipment.
We'll be featuring live demos such as AMCC's backplane Ethernet
10GBASE-KR ecosystem and Freescale's L7-Filter using their integrated
pattern matching engine.
And, you won't want to miss this outstanding lineup of technical
presenters, including:
- Kin-Yip
Liu, Director of Applications Engineering, Cavium
Networks,
will present "OCTEON Architecture Advantages for Enterprise
and Data-Center Applications."
- Mike
Hui,
IP Services Solution Architect, Freescale,
will present "Application-Aware
Networking using PowerQUICC Processors."
- Brad
Booth,
Senior Principal Engineer, AMCC, speaking on "10GBASE-KR
in The Data Center."
- Alex
Dickinson, President and CEO, Luxtera, will present "Data-Center
Interconnects using CMOS Photonics."
- Asif
Hazarika,
Senior Manager, Fujitsu Microelectronics America, speaking
on "10GbE Switch Chips for Data-Center Ethernet."
- Ori
Aruj,
General Manager North America, Dune Networks,

The seminar wraps up with a closing panel exploring
the future of data-center networks. Following the
closing panel will
be a reception complete with exhibits and a raffle
where
we'll
be giving
away an iPod Nano, as well as one of The Linley
Group's reports.
