| You
can specify that each server handle a certain percentage
of server requests, routing more requests to your more
robust servers. |
| |
| • It's
an "intelligent" round robin |
| |
| When
a server fails TZO-HA removes it from the rotation however
it continues to monitor all the servers. When the server
is back online TZO-HA automatically returns it to the
rotation and restores your originally specified weight
to each server. |
| |
| • Action
taken ONLY if both/All monitoring agents report a failure
|
| |
Servers
may be in geographically dispersed areas.
By placing the servers in different geographic areas
you can protect against regional disruptions yet continue
to balance the load among the server locations. |
| |
| • Servers
can use different Internet backbones |
| |
| Using
different Internet backbones for your servers reduces
the risk of failure due to the failure of one or multiple
Internet backbones. |
| |
| • TZO-HA
complements existing load balancing devices. |
| |
| If
you're using a load balancing device at one or more
of your installations, TZO-HA can balance the load among
your locations while your load balancing device can
balance the load within each location. Using TZO-HA
to augment your hardware load balancing devices protects
against failure of the load balancing device and protects
against the loss of connection to one or more of your
installations. |
