Virtual Connect server profiles 168

The corresponding physical functions for each port on the same adapter must have the same

personality. For example, if MZ1:1-b is iSCSI, MZ1:2-b must also be iSCSI; it cannot be Ethernet.

PXE and iSCSI can be enabled at the same time on a single port (PXE on a, iSCSI on b).

PXE and FCoE can be enabled at the same time on a single port (PXE on a, FCoE on b).

FCoE and iSCSI cannot be enabled at the same time on a single port, since they use the same PF.

After the iSCSI connections are created in the profile, VCM inventories the LOMs and mezzanines to

determine each of the physical function capabilities, and assigns a personality (Ethernet, iSCSI, FCoE) to

each PF based on connections in the profile and on the PF's capability. VCM sets the boot controller order on

the server. The server boots from the primary iSCSI boot target. If the PF personality has changed, an
automatic reboot is initiated by the adapter. After the server boots, you can configure additional iSCSI

targets from the iSCSI BIOS utility or by using OS tools.
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 the following table. 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.
