HP OneView - Manual (Page 119)

IMPORTANT: When you move a server profile to a different enclosure, and the profile is configured
to boot from a Direct attach storage device, you must manually update the boot connection of the
profile to specify the WWPN (World Wide Port Name) used for the storage device that is directly
attached to the enclosure.
Each enclosure connects to a different port of the Direct attach storage device, so the WWPN for
that storage device is different for each enclosure. If you do not specify the correct WWPN and
LUN for the storage device, the server will not boot successfully from the boot target.
15.4.1.4 Fibre Channel networks and FCoE
Servers connect to the enclosure interconnect downlinks using FCoE (Fibre Channel over Ethernet),
and uplink to SANs and Direct attach storage systems using Fibre Channel. The interconnects
automatically handle the routing between the server blades and the Fibre Channel networks, so
you do not need to specify a VLAN ID for a Fibre Channel network.
15.4.2 About Ethernet networks
You use Ethernet networks for data networks.
Ethernet networks and network sets
You can assign multiple Ethernet networks to a named group called a network set. Later, when
you add a connection in a server profile, you can select this network set to enable multiple networks
to be selected for that single connection. For information about network sets, see the online help
for the Network Sets screen.
15.4.2.1 Ethernet networks and VLAN IDs
When you add an Ethernet network to the appliance, you are adding a VLAN (virtual local area
network) to the configuration. VLANs allow multiple networks to use the same physical connections.
server profiles can specify networks without knowledge of the hardware configuration of the data
center network.
When defined on this appliance, Ethernet networks connected to enclosure interconnects require
a VLAN ID.
15.4.3 About network sets
A network set is a collection of Ethernet networks that form a named group to simplify server profile
creation. Network sets are useful in ESXi environments where each server profile connection needs
to access multiple networks. Network sets define how packets will be delivered to the server when
a server Ethernet connection is associated with the network set. Network sets also enable you to
define a VLAN trunk and associate it with a server connection.
Instead of assigning a single network to a connection in a server profile, you can assign a network
set to that connection.
•
Using network sets, you can quickly deploy changes to the network environment to multiple
servers. For example, you have 16 servers connected to a network set. To add a new network
to all 16 servers, you only need to add it to the network set instead of each server individually.
•
You can create a network set for your production networks and one for your development
networks.
•
You can configure a hypervisor with a vSwitch to access multiple VLANs by creating a network
set as a trunk that includes these networks.
