Step 8: Enabling
Communication with a Multi-Geo
System
A Lattus Multi-Geo configuration is one that spans two or three data
centers which are located in different geographic areas.
The Lattus A10 can be located at any of the locations in the Multi-Geo
system, but for optimal performance the Lattus A10 should be located
at the same data center that contains the Lattus Controller Node(s) with
which the Lattus A10 will communicate.
At a minimum, the Lattus A10 must have 10GigE connectivity to the
local Lattus Controller Node(s), as well as access to the customer’s
public network if REST connectivity is desired.
Although you can enable connectivity between a Lattus A10 and Lattus
Controller Nodes at remote sites, performance will suffer due to double
latency. Consequently, this remote configuration might be best used as
a cold spare option only.
Adding a Lattus A10 to a Multi-Geo System
Assuming you have already completed the previous configuration steps
in this guide and wish to enable connectivity between the Lattus A10
and one or more Lattus Controller Nodes in the same data center, use
the Lattus A10 GUI’s
Object Storage Destinations
page to specify the
name(s) of the local Lattus Controller Node(s).
