SolarWinds UDT installations on Windows Server 2008 R2 and Windows 7
(supported for evaluation purposes only) require a Microsoft hotfix to realize the
FIPS-compatibility features of this release. For more information about this
required Microsoft hotfix, see the article
http://support.microsoft.com/kb/981119
.
As noted in the KB article, you need to enable FIPS first before applying the
Microsoft hotfix.
Server Sizing
SolarWinds UDT is capable of monitoring networks of any size, ranging from
small corporate LANs to large enterprise and service provider networks. Most
SolarWinds UDT systems perform well on 3.0 GHz systems with 4 GB of RAM,
using default polling engine settings. However, when monitoring larger networks,
you should give additional consideration to the hardware used and the system
configuration.
There are three primary variables that affect scalability. The most important
consideration is the number of monitored ports, nodes, and users. Systems
monitoring more than 50,000 elements require 8+ GB of RAM. The second
variable to consider is polling frequency. For instance, if you are collecting
statistics more frequently than the default, the system will have to work harder and
system requirements will increase. Finally, the number of simultaneous users
accessing SolarWinds UDT directly impacts system performance.
When planning an SolarWinds UDT installation, there are four main factors to
keep in mind with respect to polling capacity: CPU, memory, number of polling
engines, and polling engine settings. For minimum hardware recommendations,
see “Requirements”. For more information about polling engines, see Appendix A
of the SolarWinds User Device Tracker Administrator Guide.
In most situations, installing SolarWinds UDT and SQL Server on different
servers is highly recommended, particularly if you are planning to monitor a high
number of ports. If you experience performance problems or you plan to monitor a
very large network, you should certainly consider this option. This scenario offers
several performance advantages, as the SolarWinds UDT server does not
perform any database processing, and it does not have to share resources with
SQL Server.
If you plan to monitor 150,000 or more ports, SolarWinds recommends that you
install additional polling engines on separate servers to help distribute the work
load. For more information about sizing SolarWinds UDT to your network, contact
