QUESTION:
What does IBM have in the way of 100 Mbit/sec Ethernet? Is FDDI the
recommended protocol if wanting that kind of throughput? Can you
please position Ethernet and where IBM is taking it?
---------- ---------- ---------- --------- ---------- ----------
A: There are several alternative solutions that provide the same or
greater throughput comparing to 100 Mbps Ethernet.
Solution provided throughput
-------- -------------------
FDDI LAN about 100 Mbps.
ATM WAN 100 Mbps
Fibre Channel WAN 266 Mbps
The following are hardware and software requirements for each of the
solutions.
FDDI
----
Hardware required:
IBM FDDI Adapter. The base adapter allows communications on a
Single-Attach Station (SAS) network, while the optional upgrade
allows communications on Dual-Attach Station (DAS) network. Below
I have referenced feature codes for both SAS and DAS solution.
Single ring ¢ Dual ring
-------------------¢---------------------
FC 2720 Original ¢ FC 2722 Original
FC 2724 New ¢ FC 2723 New
FC 2725 STP ¢ FC 2726 STP
STP - Shielded Twisted Pair.
Software required:
FDDI device driver. FC 5054.
ATM - Asynchronous Transfer Mode
--------------------------------
ATM represents a high troughput solution for Wide Area Networks.
Hardware required.
IBM Turboways 1000 ATM adapter, FC 2984.
The adapter provides a 100 Mbps connection over multimode fiber
cables to an ATM switch.
Software required.
ATM Adapter Device Driver/6000 (FC 5063) is required for the
IBM TURBOWAYS 100 ATM Adapter and must be ordered separately.
Connection to an ATM network required.
Fibre Channel Standard
----------------------
Hardware required.
IBM Fibre Channel Adapter/266. FC 1906.
Fibre optic cables are used to link the IBM Fibre Channel
Adapter/266 to the IBM 7319 Model 100 Fibre Channel Switch16/266.
Software required.
AIX Fibre Channel Adapter/266 Device Driver/6000 (FC 5062) is
required and must be ordered separately.
