2012-11-07T09:33:19-06:00 VCEFXTW210600GN vcm_svr: [PRO::6044:Info] SR-IOV Virtual Functions added to powered on server. SR-IOV will not be available until server is rebooted. : Profile: p_sriov, Server bay: 1

Virtual Connect does not send traffic back on the same downlink port on which it was received. This means that if two or more VMs are using VFs on the same PF on the host, they are not able to communicate with each other over those VFs.

If a server profile has Ethernet connections that do not map to the third PF, the adapter distributes the VFs among the PFs that do exist and no system log entry is generated.

Flex-10 configurationNetwork administrator

For each Virtual Connect network, the network administrator can set a "Preferred" and "Maximum" speed for FlexNICs that connect to that network. FlexNICs cannot connect to a network at a speed higher than the maximum speed set by the network administrator for that network. The "preferred" speed setting is the speed recommended by the network administrator for any FlexNIC that attaches to that network. The server administrator can choose to follow or disregard this recommendation.

The network administrator can change these two settings by clicking the Advanced button on the create/edit network screen. For more information, see "Multiple Networks Link Speed Settings (on page 98)."

Server administrator

The server administrator can configure a requested bandwidth for every connection in a server profile. Virtual Connect can control the link speed of FlexNICs but cannot control the link speed of traditional NICs.

The server administrator has four choices for Requested Bandwidth for each connection:

1.Preferred. Choosing "Preferred" sets the requested bandwidth equal to the bandwidth recommended by the network administrator's "Preferred" speed setting for that network. If the administrator has not configured a preferred bandwidth for the network, this setting is treated the same as "Auto".

2.Custom. Choosing "Custom" enables you to specify a number between 100Mb and 20Gb (in increments of 100Mb) for requested bandwidth.

3.Auto. Choosing "Auto" evenly distributes the available bandwidth between all connections assigned to "auto".

4.Disabled. VC determines the bandwidth speed.For more information, see "Bandwidth assignment (on page 175)."

Although the Port Speed Setting is available for all network connections in a profile, Virtual Connect can only control link speed for Flex-10 NICs when they are connected to an HP Virtual Connect Flex-10 Module. Virtual Connect cannot control the link speed of traditional NICs. Enabling specification of port speed regardless of the underlying NIC allows the profile to configure the connection automatically when moved to or from Flex-10 enabled servers and NICs.
