17 Dell OpenManage Plug- in Version 2.0 for Oracle Enterprise Manager 12c | A00
5 Best practices
The following are the best practices recommended for implementing and using Dell OpenManage Plug- in
for Oracle Enterprise Manager:
5.1 Dell PowerEdge servers
To monitor Dell PowerEdge 12th generation (12G) servers, it is recommended to use agent- free, out- of-
band method, using Integrated Dell Remote Access Controller 7 (iDRAC7). By using out- of- band
management, IT administrators no longer need to install or periodically certify/validate traditional in- band
OpenManage Server Administrator (OMSA) installed on the server. The out- of- band management method
allows IT administrators to effectively monitor Dell systems with increased availability from any location,
without the use of agents, and regardless of the operating system or hypervisor presence or state.
Alternatively, Dell PowerEdge servers from 9th generation (9G) to 12th generation (12G) can be monitored
using in- band method through OpenManage Server Administrator (OMSA) installed server. This includes
Microsoft Windows, Red Hat Enterprise Linux (RHEL), SUSE Linux Enterprise Server (SLES), ESX/ESXi,
Hyper- V, and Citrix XenServer support. OMSA is currently not supported on Oracle Linux operating system.
To monitor servers running Oracle Linux operating system, use iDRAC7 supported only with PowerEdge
12G servers. The
Dell OpenManage Server Administrator Support Matrix can be accessed at

.
5.2 Dell OpenManage Essentials
While discovering devices in OpenManage Essentials, for optimal operation it is recommended to:
• Discover target devices running Linux operating system using SSH protocol and iDRAC using WS-
Man protocol
• Discover target devices running Windows operating system using WMI protocol and iDRAC using
WS- Man protocol
• If OMSA is installed and supports the operating system of the target device, SNMP protocol can
also be used instead of the SSH/WMI protocol
• In server generations prior to Dell PowerEdge 11G, WS- Man protocol is not supported for
discovering iDRAC; SNMP protocol must be used instead.
Discovering devices using the recommended protocol in OpenManage Essentials enables OpenManage
Plug- in for OEM to discover Dell devices, and for the automatic association of the server- to- database to
happen in the Oracle Enterprise Manager console.
