RapiDeploy Technical Reference
-threshold: [n] Function This option applies only to the “Restore and Send” (-
mdb) mode. We have found that when using a small number of
clients, it is faster to perform individual downloads on each
client than it is to multicast to all of them. There is a point where
it becomes more efficient to multicast than it is to perform
individual downloads. This “threshold” is where it becomes
faster to multicast than to do individual downloads and can be
specified by the -
threshold:
[n] command line parameter.
Depending upon the network environment, this number may
vary. You should perform a few tests to pick a good threshold
value for your network. It may be a small number, like four, or it
could be much larger, like 15.
Once you have found this threshold value, you can specify this
number on the command line and then RapiDeploy will,
depending on the number of clients that connect, have them do
individual downloads or have them multicast.
The number [n] specifies the minimum number of clients that
will need to connect to the master in order for it to multicast.
Example: if you specify
-threshold=5
, and four or fewer
clients connect to the master PC, it will have them all do
individual downloads of the image. If five or more clients
connect to that master, it will multicast to them.
This becomes more important when multicasting across subnets
with a router that doesn't support multicasting. If you start one
master and nine clients (10 PC's total), three of which are on
one side of the router and seven of which are on the other side,
RapiDeploy will detect that there are only three on one side of
the router and do individual downloads to them. It will also
detect that seven are on the other side and multicast to them.
RapiDeploy does all of this automatically. All you must supply is
the threshold value to let RapiDeploy determine when it should
multicast or not.
Example
Suppose you have determined that the threshold value for your
network is five. In other words, you have found that
multicasting from one master to five or more clients is faster
than doing individual downloads to those clients and the master.
You could then specify the following threshold value on the
command line:
rdeploy -mdb -f
[filename]
-s9 -threshold:5

PCs]
-throttle:[

Function Throttle RDeploy operations to N mbps.
