You can use zones to specify a physical location of your
appliance. This physical location might be two different areas of
a power grid within the same data center, or appliances that are in
completely different data centers, perhaps in different parts of the
country.
Before you begin
Before you create
and configure zones, you must install, configure,
and assemble your appliances into a collective. You can then select
the appliances in your collective to be in particular zones. If you
add an additional appliance to the collective after zones have been
created, you can specify the zone when you add the appliance.
About this task
By specifying zones to physically demarcate the location
of your appliances, the data that is stored in your
data grids can be placed in a proper
location. The
DataPower® XC10 Appliance uses
zones to determine where to place primary and replica information
for the cache. For example, if a primary
data grid is in zone 1, then the
replica for that
data grid would
be in zone 2. If you only have one zone, then no replicas are created.
When
an appliance is first initialized, it is added to the default zone,
which is called DefaultZone. When you add your
appliances to zones that you create, they are removed from the DefaultZone zone.
You cannot add appliances back to the DefaultZone zone
after they have been removed.
Procedure
- In the user interface, click .
- Add zones. Click Add
Zones.
Specify a name for the zone that you want to add. The zone name displays
on the console page. You can repeat these steps if you are creating
multiple zones.
- Add appliances to the zone. Expand the zone
name and select appliances to add to the zone. Repeat these steps
until all your appliances in the collective have been added to zones.
Each appliance must be in a zone. A single zone cannot contain appliances
from different collectives.
- Apply the zone
changes. Your zone changes are
not effective until after you click Activate Zone Changes.
If you want to change your zone information, you can click the delete
icon (
) to remove a zone or click Reset
Zone Changes to reset the zones to the last configuration
that you activated.
Results
DataPower XC10 Appliance can
create primary and replica data caches based on the physical locations,
or zones, that you defined. You can view or change the topology of
your zones at any time by clicking in the
user interface.
