JNIC-1460/1560
Fibre Channel-to-PCI/PCI-X ASIC Controller
Data Sheet
For nearly a decade, JNI ASICcontrollers 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 —AMCCis proud to offer JNIC ASIC controllers for a variety of SANapplications.
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.
