<h4 id="scnwsh">Network server host adapters</h4>
|
||
|
|
<p>The network server host adapter (NWSH) device description object shown
|
||
|
|
in <a href="rzahqscattixaixs.htm#rzahqiscinosec">Figure 15</a> represents the iSCSI host bus adapter (HBA)
|
||
|
|
that is used by the iSeries™ side of the iSCSI connection:</p>
|
||
|
|
<ul>
|
||
|
|
<li>It identifies the iSeries hardware resource name (for example, LIN33) for
|
||
|
|
the iSCSI HBA.</li>
|
||
|
|
<li>It defines how communications errors are logged and communications recovery
|
||
|
|
information.</li>
|
||
|
|
<li>It defines the internet addresses, ports, and so on. for the SCSI and
|
||
|
|
LAN interfaces on the iSCSI HBA.</li></ul>
|
||
|
|
<p>The iSeries can have multiple iSCSI HBAs, each with an associated NWSH object.</p>
|
||
|
|
<ul>
|
||
|
|
<li>Each NWSH can be shared by multiple integrated servers. In configurations
|
||
|
|
where bandwidth is not a concern, this results in a lower cost solution.</li>
|
||
|
|
<li>Each integrated server can use multiple NWSHs. This allows multiple SCSI
|
||
|
|
and virtual Ethernet data paths between the iSeries and the xSeries® or IBM® BladeCenter™ systems, which can provide greater
|
||
|
|
bandwidth and connection redundancy.</li></ul><img src="deltaend.gif" alt="End of change" />
