<h3 id="rzahqperfve">Virtual Ethernet</h3>
|
||
|
|
<p>The Virtual Ethernet point to point connection is the default virtual network
|
||
|
|
connection between the iSeries™ hosting partition and each integrated Windows server.
|
||
|
|
The point to point connection is used primarily for administrative operations
|
||
|
|
which are part of the integration environment.</p>
|
||
|
|
<p>The iSeries and Windows CPU utilization cost of using the point to point
|
||
|
|
connection is similar to the utilization cost of using a hardware network
|
||
|
|
adapter. The connection is high speed, but total bandwidth is always shared
|
||
|
|
with disk, tape and other operations on IXS and IXA adapters. When you use
|
||
|
|
internet SCSI (iSCSI), you can separate virtual Ethernet operations by using
|
||
|
|
another iSCSI HBA channel.</p>
|
||
|
|
<p>A Virtual Ethernet connection between two or more integrated servers uses
|
||
|
|
the iSeries CPU to switch the traffic between servers, even when the iSeries server is not an endpoint of the traffic. For most connections this
|
||
|
|
utilization won't be significant. But, if you expect high sustained network
|
||
|
|
loads across the virtual Ethernet connection between integrated servers, you
|
||
|
|
might want to balance the cost of using the Virtual Ethernet internal switch
|
||
|
|
against external network adaptors on the integrated servers.</p><img src="deltaend.gif" alt="End of change" /><img src="deltaend.gif" alt="End of change" />
