Example: Display the Physical Servers Connected
to the Chassis
The OVN host drivers communicate with Xsigo’s OpenSM by default. When an IB
connected host server boots up, the installed OVN host driver advertises the server’s
host name to the Oracle Fabric Interconnect.
Issue show physical-server command to display the list of InfiniBand-
connected servers:
The alexander server is connected to the Oracle Fabric Interconnect named “iowa”
on IB port 8 (iowa:ServerPort8).
When you issue add server-profile
<name>, you will see the reported host
server names for which command completion can configure:
m-key Management key. A construct that is contained in InfiniBand Architecture
(IBA) management datagrams to authenticate the sender to the receiver.
lid Local Identifier. An address assigned to a port by the IB Subnet Manager
(SM), unique within the subnet, used for forwarding packets within the
subnet. The SM manages the switching and routing tables with the IB
fabric. The Source and Destination LIDs are present in the Local Route
Header. A Local Identifier is formed by the sum of the Base LID and the
value of the Path Bits. Unlike a fixed GUID, a LID can change from time-
to-time.
sm-lid The LID where the master SM is located. It is not the SM priority value.
link-width
link-speed
Link-width is the number of physical lanes (1, 4, 8, or 12) whereas link
speed is the speed of the physical lanes, such as 2.5 Gbps (SDR), 5 Gbps
(DDR), or 10 Gbps (QDR). If the link-width field is not 4x, there is
something wrong.
The InfiniBand Architecture (IBA) defines a number of different link bit
rates. The lowest bit rate of 2.5 Gbps is referred to as a 1x (times one)
link. Other link rates are 10 Gbps (4x) and 30 Gbps (1x2).
