<strong>vSphere</strong> <strong>Storage</strong><br />
n Turn on Priority-based Flow Control (PFC) and set it to AUTO.<br />
<strong>VMware</strong> recommends that you use the following firmware on the FCoE switch:<br />
n Cisco Nexus 5000: version 4.1(3)N2 or higher.<br />
n Brocade FCoE switch: version 6.3.1 or higher.<br />
Network Adapter Best Practices<br />
If you plan to enable software FCoE adapters to work with network adapters, specific considerations apply.<br />
n Make sure that the latest microcode is installed on the FCoE network adapter.<br />
n If the network adapter has multiple ports, when configuring networking, add each port to a separate<br />
vSwitch. This practice helps you to avoid an APD condition when a disruptive event, such as an MTU<br />
change, occurs.<br />
n Do not move a network adapter port from one vSwitch to another when FCoE traffic is active. If you need<br />
to make this change, reboot your host afterwards.<br />
n If you changed the vSwitch for a network adapter port and caused a failure, moving the port back to the<br />
original vSwitch resolves the problem.<br />
Set Up Networking for Software FCoE<br />
Before you activate the software FCoE adapters, you need to connect the VMkernel to physical FCoE NICs<br />
installed on your host.<br />
Procedure<br />
1 Log in to the <strong>vSphere</strong> Client, and select a host from the inventory panel.<br />
2 Click the Configuration tab and click Networking.<br />
3 In the <strong>vSphere</strong> standard switch view, click Add Networking.<br />
4 Select VMkernel and click Next.<br />
5 Select Create a <strong>vSphere</strong> standard switch to create a new <strong>vSphere</strong> standard switch.<br />
6 Select the network adapter (vmnic#) that supports FCoE and click Next.<br />
If your host has multiple network adapters or multiple ports on the adapter, you can add all of them to a<br />
single <strong>vSphere</strong> standard switch. An alternative is to connect each FCoE NIC to a separate standard switch.<br />
NOTE <strong>ESXi</strong> <strong>5.0</strong> supports the maximum of four network adapter ports used for software FCoE.<br />
7 Enter a network label.<br />
Network label is a friendly name that identifies the VMkernel adapter that you are creating, for example,<br />
FCoE.<br />
8 Specify a VLAN ID and click Next.<br />
Because FCoE traffic requires an isolated network, make sure that the VLAN ID you enter is different from<br />
the one used for regular networking on your host. For more information, see the <strong>vSphere</strong> Networking<br />
documentation.<br />
9 Specify the IP settings and click Next.<br />
10 Review the information and click Finish.<br />
You have created the virtual VMkernel adapter for the physical FCoE network adapter installed on your host.<br />
NOTE To avoid FCoE traffic disruptions, do not remove the FCoE network adapter (vmnic#) from the <strong>vSphere</strong><br />
standard switch after you set up FCoE networking.<br />
