than OME. Please refer to the whitepaper “Installing Dell OpenManage Essentials” for more
information about installing Dell OME on a remote Database.
Generic recommendations
Based on the analysis of the performance data collected for the various features tested, the
following are the recommendations:
1. The minimum hardware and software mentioned in Table 1 must be used in order for better
performance of OME. Higher hardware specifications i.e., increase in processor cores or RAM will
yield better performance that that detailed out in the rest of the document.
2. Recommendation is to configure the “max server memory” of SQL server based on the available
system resources. Please refer to the MSDN link for more information.
3. OME must be installed using a remote database when the number of managed system is >500 and
if the hardware specification is that provided in Table 1.
4. Domain Name System (DNS) must be configured such that OME is able to resolve the hostname of
all the managed systems.
