Operational Overview 17
A separate network increases the security of the management network
because you can physically control which workstations are connected to the
network.

An iLO Shared Network Port using the server's NIC instead of the dedicated
iLO management NIC for server management. This configuration simplifies
the network and reduces total network cost. Fewer cables, hubs, and switches
are needed because both regular and iLO network traffic comes through the
system NIC.
The main disadvantage of using the iLO Shared Network Port for iLO server
management is the lack of speed compared to the dedicated iLO management
NIC. As a result, not all iLO management features are available through the
iLO Shared Network Port configuration.
Supported Server Operating System Software
iLO is an independent microprocessor running an embedded operating system.
The architecture ensures that the majority of iLO functionality is available,
regardless of the host operating system.
Graceful host operating system shutdown, Insight Manager 7, and Systems
Insight Manager integration require Health Drivers and Management Agents or
remote console access.
iLO provides two interface drivers:
iLO Advanced Server Management Controller Driver (Health Driver)—This
driver provides system management support, including monitoring of server
components, event logging, and support for the Management Agents.
iLO Management Interface Driver—This driver enables system software and
SNMP Insight Agents to communicate with the iLO.
These drivers and agents are available for the following network operating
systems:
Microsoft®
− Windows NT® 4.0 Server
− Windows NT® 4.0, Enterprise Edition
