Data Center Management Interface
The iRMC supports the DCMI (Data Center Management Interface) protocol, which is
compliant with the IPMI V2.0 standard. DCMI has been designed to improve
manageability and energy efficiency of server systems that are deployed in large data
centers.
To meet the hardware management requirements of servers within data centers, DCMI
supports, among others, the following key features:
Inventory functions (server identification)
l
Power Management and power monitoring
l
Power consumption monitoring and control
l
Event logging
l
Temperature monitoring
l
Detailed information about DCMI can be found on the Internet.

Serial over LAN (SOL)
"Serial Over LAN" is an interface compliant with the IPMI V2.0 standard, which
controls transfer of serial data over a LAN connection. In particular, SOL specifies the
packet formats and protocols for transferring serial data streams over a LAN between
the serial controller on the managed computer and a remote workstation. SOL is
based on the IPMI- over-LAN specification.
In order to establish a SOL connection, a remote management application first initiates
an IPMI-over-LAN session with the BMC. After this has been done, the SOL services
can be activated from the remote workstation. The data traffic between the serial
controller and the remote workstation is handled over the same IPMI session as the
IPMI commands.
As soon as an SOL connection has been established, data transfer between the serial
controller and the remote workstation is carried out as follows:
Transfer from the serial controller to the remote workstation:
l
The data stream issued by the serial controller is partitioned by the BMC,
packaged and then sent to the remote workstation over the LAN.
Transfer from the remote workstation to the serial controller:
l
BMC unpacks the characters contained in the packages sent by the remote
workstation and forwards them to the serial controller as a character stream.
