Table 2-15 Stacking Methods
Dynamic Stacking
Static Stacking
All servers in a stack must be configured with the same 'Stack Name.' When naming, it is
suggested that you create a new domain for the stack, and then place each server in that
domain. For example, the Company Corporation may create the domain "company.com"
for its OmniTouch ACS stack, and then name each server in the stack using the following
sequential format.
Alcatel-Lucent1.company.com
Alcatel-Lucent2.company.com
You should also configure your DNS server to cycle among the servers (DNS Round
Robin) in your stack when resolving Stack Name, so that users can address the stack
through a single fully qualified domain name (FQDN).
Each server must have a unique Node ID. This Node ID will be used as the first two digits
of all conference access codes for this server's users.
Note:
owned by that Application Server will no longer be valid.

If you change a system's Node ID, all pre-existing conference access codes
This "plug and play" setting is the preferred
configuration for stacks where all servers are co-
located. All servers connected through the IP
Stack Backplane that are configured with
identical Stack Names will automatically
discover each other and form the stack. Since
each server's secondary IP addresses will be set
automatically based on its configured (manually
assigned) unique node ID, Dynamic stacking
requires that the secondary Ethernet switch, the
Stack Backplane, be dedicated to the stack with
no outside connections.
It is possible to statically configure a stack's IP
addresses. This may be necessary, for example, if
a stack is geographically distributed between
cities. Static stacking requires that you specify
the Name, Primary IP Address, and Backplane
IP Address of all the servers in the stack. (You
may statically configure up to 10 servers in a
single stack.) Each server in the stack must be
manually configured with these parameters.
Also, for PSTN stacks, each PSTN gateway card
has an Ethernet port, which will also require a
static address.
