Distributed/HA Hardware Requirements
The distributed server hardware guidelines are based on average OpenManage Network Manager
application use on your managed network (Table 5-1). These guidelines include number of users,
number of devices managed, Traffic Flow Analysis (TFA), Performance Management (PM), and
Event Management (EM) as the most demanding elements.
Distributed installations consist of separate servers for separate functions within the OpenManage
Network Manager system. Web server (WS), Application server (AS), Mediation server (MS), and
Database server (DB) are on separate hosts. The RAM, CPU and hard drive (HD) sizes for these are
provided. All CPUs and/or cores should be 3.0GHz or faster.
For sizing recommendations not covered here, contact your sales representative.

PM supports 600 inserts per second using a single disk (SSD) Drive. 1 insert = 1 monitored attribute. Performance improves
as you add drives and worsens with slower drives.
5
EM supports a sustained 200 traps per second using a single (SSD) drive. Performance improves as you add drives and
worsens with slower drives.
6
Mediation recommendations assume managing <1000 devices per host.
