●
Number of phones to be managed: Cisco Unified Provisioning Manager is tested at several tiers, and
hardware recommendations are listed below for each tier. The number of phones to be managed has a
major impact on disk performance requirements, especially during device sync operations.
●
Concurrent user load on the system: The responsiveness of the system may change as more concurrent
users are added. More concurrent administrators generally require more CPU for processing and memory
for user space. The 10,000 and lower phone recommendation assumes 1 to 5 operators. The 20,000
phone and larger phone recommendation assumes up to 10 concurrent users. In smaller environments
with more than 5 concurrent administrators, you should consider going to a faster computer tier to assure
responsiveness. See the section “VMware Support in Provisioning Manager” for virtualization
recommendations.
●
Network growth effect on hardware: As the number of phones increases, the number of concurrent
administrators will usually also increase. Sometimes the increase in managed phones will cause the
hardware platform to be upgraded. It is a good practice to look at growth requirements versus platform cost
depreciation to decide which tier of performance should be considered for the initial purchase.

How to Select the OS
●
Cisco Unified Provisioning Manager is supported with off-the-shelf Windows Server 2003 or 2008.
◦
The latest service pack, currently Service Pack 2, should be installed
●
Windows Server 2003/2008: Standard and Enterprise
◦
Cisco Unified Provisioning Manager is tested on both versions. Choosing which one to use is based on
the amount of RAM and swap (virtual memory/page file) space required. The Standard version, for
example, will only allow a maximum of 4 GB of swap space. If you feel you need more swap space, use
the Enterprise version
●
32-bit or 64-bit OS
