If FCoE connections are configured, VCM sets the FCoE personality to the PF. If FC boot parameters are

configured, VC Manager writes these to the NIC and sets the boot order as it does in the case of iSCSI boot
parameters.
In the first example, a profile with eight Ethernet and two FCoE connections is assigned to a server with a

1-Gb LOM and a dual-port 57711 Broadcom MEZ card in MEZ1 and a CNA in MEZ2. The results of the

mapping algorithm are shown in Table 2. Each 1-Gb LOM port only has one connection assigned.

In the second example, a profile with two iSCSI, ten Ethernet, and two FCoE connections is assigned to a
server with a Flex-10 LOM and NC551m dual-port MEZZ card in MEZZ1 and MEZZ2. The results of the

mapping algorithm are shown in the following table.

The third example is similar to the second except that the LOM is the NC551i. The example compares ten
Ethernet, one iSCSI, and four FCoE connections. The second PF on MEZZ2:Port 2 has to be enumerated as

iSCSI since the corresponding PF on port 1 is iSCSI. But, since there is only one iSCSI connection defined in

the Profile, the second PF on MEZZ2:Port 2 is disabled.

Bandwidth assignment

In Flex-10 environments, four FlexNICs must share a single 10Gb link. Each FlexNIC is allocated a portion

of that 10Gb link's bandwidth. The bandwidth assigned to the four FlexNICs in a single physical port cannot

exceed 10Gb, but the requested bandwidth settings you specified in the profile might exceed 10Gb.
