HP OneView - Manual (Page 138)

Servers connecting to a Direct attach Fibre Channel network have access to all devices connected
on the uplink ports defined for that network. If there is more than one connection from a FlexFabric
module to the storage system, each server can access as many paths to the storage LUN (logical
unit number) as there are connections to the storage system.
For Direct attach Fibre Channel networks, the enclosure interconnect does not distribute server
logins evenly across uplink ports. Server login-balancing and login-distribution do not apply to
Fibre Channel networks.
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.
18.3.4 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 (virtual local area network) ID for a Fibre Channel network.
18.3.5 Managing Fibre Channel networks (SANs)
You can manage Fibre Channel networks from the UI Networks screen or by using the REST APIs.
18.3.5.1 Roles
•
Minimum required privileges: Infrastructure administrator or Network administrator
18.3.5.2 Tasks for Fibre Channel networks
The appliance online help provides information about using the UI or the REST APIs to:
•
Add and delete a Fibre Channel SAN.
•
Edit a Fibre Channel SAN configuration.
18.4 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.
18.4.1 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.
