Achieving Scalability In The Real World - Novell ZENWORKS 10 CONFIGURATION MANAGEMENT SP3 - SYSTEM PLANNING-DEPLOYMENT-BEST PRACTICES GUIDE 10.3 30-03-2010 System Planning Manual

The graph illustrates the probable scalability limitations of the Satellite device. Under normal load,
and through the use of proper configuration parameters (for example, randomizing distributions and
collections) we can comfortably conclude that a Satellite device running on server-class hardware
and Windows Server can scale to approximately 1,000 managed devices, and a Satellite device
running on workstation-class hardware and Windows XP or Vista can scale to approximately 250
managed devices.
Test 2: Server OS Delivering Multiple Chained Bundles
This test shows the results of a Satellite device running on a server OS delivering multiple chained
bundles to connected managed devices. This information is useful when calculating how much load
you can place on the Satellite device running on a Server OS when deploying applications that are
chained. This obviously can differ greatly from deploying single bundles.

Test 3: Workstation OS Delivering Multiple Chained Bundles
This test shows the results of a Satellite device running on a workstation OS delivering multiple
chained bundles to connected managed devices. This information is useful when calculating how
much load you can place on the Satellite device on a workstation OS when deploying applications
that are chained together. This obviously can differ greatly from deploying single bundles.

3.3.3 Achieving Scalability in the Real World

The testing in the SuperLab tests the upper limits of a Satellite device. It is important to note that if
you are deploying a bundle that is less than 25 MB in size, we see successful distributions to both
250 and 1,000 managed devices from workstation-class and server-class Satellite devices. With this
as a known, we can safely assume that by doing the following, you can achieve these levels of
scalability, and quite possibly much more:
For larger sites (more than 250 managed device):
Have a dedicated Satellite device for imaging purposes.
Have a dedicated Satellite device for inventory collection if the collection frequency is
high. In other words, if you are collecting daily, you want the server to be dedicated, but if
you are collecting monthly, you can collapse this service into another Satellite device
onsite.
