<h1 class="topictitle1">Gigabit and 10 Gigabit Ethernet </h1>
|
||
|
|
<div><p>The <span class="keyword">iSeries™</span> server
|
||
|
|
supports Gigabit and 10 Gbps Ethernet, which requires the use of a 1 Gbps
|
||
|
|
or 10 Gbps input/output adapter (IOA).</p>
|
||
|
|
<p><img src="./delta.gif" alt="Start of change" /> There are six IOAs that can be used to run Gigabit Ethernet,
|
||
|
|
the 2760, 5701, and 5706 Unshielded Twisted Pair (UTP) adapters, which use
|
||
|
|
copper wire cabling, and the 2743, 5700, and 5707 Gigabit Ethernet cards,
|
||
|
|
which use fiber optics. The fiber optic 573A and 576A IOAs support 10 Gbps
|
||
|
|
Ethernet. All of the adapter cards support Transmission Control Protocol/Internet
|
||
|
|
Protocol (TCP/IP), 9000-byte jumbo frames, and the IEEE 802.3 standard.<img src="./deltaend.gif" alt="End of change" /></p>
|
||
|
|
<p><img src="./delta.gif" alt="Start of change" />i5/OS does not have integrated support for SNA over Gigabit
|
||
|
|
or 10 Gbps Ethernet. Enterprise Extender or AnyNet is required to run SNA
|
||
|
|
over Gigabit or 10 Gbps Ethernet.<img src="./deltaend.gif" alt="End of change" /></p>
|
||
|
|
<p><img src="./delta.gif" alt="Start of change" />The UTP cards have the capability of running 10BASE-T/100BASE-TX/1000BASE-T
|
||
|
|
in full or half duplex mode. The recommended minimum cabling type for use
|
||
|
|
between these cards and their link partner is Category 5e, which has copper
|
||
|
|
twisted pair wiring. All four pairs are used when running Gigabit Ethernet.
|
||
|
|
The cable and connectors must also be wired to TIA/EIA 568-B standard. Crossover
|
||
|
|
cables are not supported.<img src="./deltaend.gif" alt="End of change" /></p>
|
||
|
|
<p><img src="./delta.gif" alt="Start of change" />The Gigabit fiber optic cards only support 1000BASE-SX in
|
||
|
|
full duplex mode. The 10 Gigabit fiber optic cards only support 10Gbase-LR
|
||
|
|
and 10Gbase-SR in full duplex mode. The 2743 and 576A use duplex SC connectors
|
||
|
|
while the 5700, 5707, and 573A use duplex LC connectors. The recommended fiber
|
||
|
|
to use with the 2743, 5700, 5707, and 573A IOAs is 50 or 62.5 micron MMF (multi
|
||
|
|
mode) fiber. 9 micron SMF (single mode) fiber is recommended for the 576A.<img src="./deltaend.gif" alt="End of change" /></p>

models.</div>
|
||
|
|
<p>Ethernet frames can contain anywhere from 64 to 9000 bytes of information.
|
||
|
|
All of these cards support the largest, 9000-byte jumbo frame size. The amount
|
||
|
|
of work for the adapter card to process each frame, regardless of size, is
|
||
|
|
nearly the same. Therefore, you want to pack the most information possible
|
||
|
|
into each frame. The final result will be to decrease processor utilization,
|
||
|
|
leaving it more available for other application usage.</p>
