JNIC-1460/1560

Fibre Channel-to-PCI/PCI-X ASIC Controller

For nearly a decade, JNI® ASIC controllers have been a pioneering presence in the Fibre Channel world.

Now that JNI has joined AMCC — the industry leader in high performance integrated circuits for wide

area networks — AMCC is proud to offer JNIC ASIC controllers for a variety of SAN applications.

Benefits

JNIC-1460

• Support for 1 or 2Gb SANs

• Two independent controllers assure

full throughput for each port

JNIC-1560

• Dual independent Fibre Channel

(FC) ports offer a sustained

bandwidth of 800MB/s with a

maximum burst rate of 1.064GB

The JNIC-1460 PCI-to-Fibre Channel

Controller

The 2Gb-enabled JNIC-1460 offers a flexible

architecture that can be easily integrated

into a variety of I/O applications. combines.

With Full-Duplex Fibre Channel data transfer

rates of up to 400 MB/s and a 64-bit, 66 MHz

PCI host interface, it delivers the unparalleled

I/O performance demanded by next-genera-

tion SAN appliances.

This powerful ASIC integrates a wide array of

advanced I/O technologies to enhance total

system performance. Starting with an embed-

ded I/O engine that performs real-time con-

text switching to maximize SAN data

throughput, the engine can queue up to 254

active exchanges on-chip. Additional active

exchanges can be accommodated on the

local memory port. JNIC-1460 proprietary data

flow architecture allows for a very efficient, low

latency data path for both receive and trans-

mit channels. An integrated RISC-based I/O

engine with large instruction RAM significantly

reduces host CPU utilization while requiring

less than one interrupt per I/O operation. This

makes the JNIC-1460 an ideal candidate for

high-end servers and external Fibre Channel

storage applications.

The JNIC-1560 Dual Channel

PCI-X-to-Fibre Channel Controller

This fifth-generation Fibre Channel I/O con-

troller provides two fully independent, high

performance FC ports for high bandwidth I/O

paths to a storage area network (SAN). The

controller can sustain an unprecedented 800

MB I/O, the highest in its class. Furthermore, it

can burst to the host system at full PCI-X

speed of 1.064 GB. Two integrated multi-task

RISC-based I/O engines minimize host CPU

overhead, making the JNIC-1560 an ideal can-

didate for high-end servers and high-perform-

ance embedded storage applications.

The JNIC-1560 employs a wide array of I/O

technologies to enhance total system per-

formance. The two embedded engines handle

context switching to maximize data through-

put in an enterprise SAN environment, where

a large number of initiators and targets are

integrated to make up the SAN. These on-

board engines can each queue up to 254 on-

chip active exchanges per channel. Optionally,

they can operate on over 32,000 locally stored

active exchanges. These engines employ a

unique I/O delivery scheme that continuously

chains I/Os as issued by the operating system,

reducing the number of system interrupts per

I/O to below one.

With support for 126 individual AL_PA aliases

per port, the JNIC-1560 is well-suited for custom

embedded target applications. Its low power

dissipation eliminates the requirement of a heat

sink in physically confined environments.
