The Allocated Bandwidth column displays "not allocated" until the profile is assigned to a device bay that
contains a server. At that time, bandwidth is allocated to each connection and the result is reported in this
column. See "Bandwidth assignment (on page
)."
The Mapping column describes how each connection of a profile is assigned to physical devices in a
server, and to which interconnect bay that device is connected. The four FlexNICs on port 1 of a server
LOM that supports Flex-10 are numbered LOM:1-a, LOM:1-b, LOM:1-c, and LOM:1-d. If a LOM does not
support Flex-10, then it is simply referenced by its port number (for example, LOM:1 or LOM:2).
Port assignment
A server profile is simply a list of connections and other parameters until that profile is applied to a
physical server. The same profile can be mapped to server hardware differently depending on the
presence or absence of different mezzanine cards, and if Ethernet devices in the server are capable of
supporting Flex-10.
In versions of firmware prior to VC 2.00 (versions that do not support Flex-10), server profile connections
are assigned to a half-height server in the following order:
1.
Assign a connection to LOM port 1.
2.
Assign a connection to LOM port 2.
3.
Assign a connection to MEZ1 port 1 (if present).
4.
Assign a connection to MEZ1 port 2 (if present).
5.
Assign a connection to MEZ2 port 1 (if present).
6.
Assign a connection to MEZ2 port 2 (if present).
7.
Assign a connection to MEZ2 port 3 (if present).
8.
Assign a connection to MEZ2 port 4 (if present).
Connections are assigned to full-height servers in a similar way, but MEZ1 could have four ports and an
additional mezzanine slot (MEZ3) exists.
Virtual Connect v2.00 and higher implements the same assignment algorithm with the exception that the
algorithm repeats for all remaining unassigned profile connections. Additional profile connections can be
assigned to Flex-10 capable devices with a maximum of four connections per Flex-10 capable port.
For example, a profile with eight connections is assigned to a half-height server with a Flex-10 LOM and
a traditional NIC mezzanine in MEZ1 in the following order:
1.
Assign profile connection 1 to LOM port 1.
2.
Assign profile connection 2 to LOM port 2.
3.
Assign profile connection 3 to MEZ1 port 1.
4.
Assign profile connection 4 to MEZ1 port 2.
5.
Assign profile connection 5 to LOM port 1 because it is Flex-10 capable and can support up to four
connections.
6.
Assign profile connection 6 to LOM port 2 because it is Flex-10 capable and can support up to four
connections.
7.
MEZ1 is not Flex-10 capable in this example, so additional connections cannot be assigned to
MEZ1. Therefore, assign profile connection 7 to LOM port 1 because it is Flex-10 capable and can
support up to four connections.
