<h3 id="hsl">HSL OptiConnect</h3>
|
||
|
|
<p>HSL OptiConnect is the term used to refer to the OptiConnect licensed software
|
||
|
|
providing high speed server-to-server connectivity between two or three servers
|
||
|
|
which are connected to each other through an HSL OptiConnect loop. It also
|
||
|
|
refers to the HSL Loop technology used to connect two or three physical servers
|
||
|
|
together on a single loop. Each server may have one or more LPAR partitions
|
||
|
|
participating in the OptiConnect network.</p>
|
||
|
|
<p>While each HSL OptiConnect loop is limited to three servers, OptiConnect
|
||
|
|
software will support multiple HSL OptiConnect loops between servers, providing
|
||
|
|
loop redundancy in addition to the hardware redundancy provided within each
|
||
|
|
HSL loop. It should be noted that any LPAR partition on the server may be
|
||
|
|
allowed to participate in the HSL OptiConnect loop functions without additional
|
||
|
|
cost.</p>
|
||
|
|
<p>To activate Virtual OptiConnect communications between LPAR partitions,
|
||
|
|
the OptiConnect licensed software must be installed on all of the partitions
|
||
|
|
where you want to use Virtual OptiConnect and the OptiConnect subsystem must
|
||
|
|
be started on each of these partitions.</p>
|
||
|
|
<p>On 5xx models, from the Hardware Management Console (HMC), select Server
|
||
|
|
Management and then select the local partition profile properties. Under the
|
||
|
|
OptiConnect tab select Use High Speed Link (HSL) OptiConnect. In order for
|
||
|
|
the change to take effect, you must activate the partition from the HMC.</p>
|
||
|
|
<p>On 8xx models, use the dedicated service tools (DST) or system service
|
||
|
|
tools (SST) to configure each LPAR partition into the HSL OptiConnect loop
|
||
|
|
environment. From the primary partition set the communication option "Connect
|
||
|
|
to HSL OptiConnect" to "yes" for each partition (in addition to the primary)
|
||
|
|
that uses the OptiConnect function.</p>
|
||
|
|
<p>The following figure shows an example of two servers that are connected
|
||
|
|
through an HSL OptiConnect loop. When OptiConnect software is installed and
|
||
|
|
running, a high-speed server-to-server connection is maintained. Two servers
|
||
|
|
can have more than one HSL loop that connects them together, providing the
|
||
|
|
server model supports more than one HSL OptiConnect loop.</p>

|
||
|
|
<p>There are two HSL cabling types: HSL and HSL-2. Servers and expansion units
|
||
|
|
may have HSL or HSL-2 cable ports, depending on the model. Both types are
|
||
|
|
supported on an HSL OptiConnect loop by using an HSL to HSL-2 cable.</p>
|
||
|
|
<p>HSL OptiConnect loops also support the use of HSL fiber-optic cables. This
|
||
|
|
technology is offered on some models. The entire HSL OptiConnect loop must
|
||
|
|
use the fiber-optic cables.</p>
|
||
|
|
<p>The following figure shows an example of a three-server HSL OptiConnect
|
||
|
|
loop. All servers in a three-server HSL OptiConnect loop must be at the minimum
|
||
|
|
operating system release level of the most current hardware.</p>
