HP 1.10GB Virtual Connect Ethernet Module for c-Class BladeSystem - Manual (Page 111)

Virtual Connect fabrics 111
To create a proper Virtual Connect fabric, all VC-FC uplinks that are included in the fabric must be connected
to the same physical SAN fabric. If the fabric uplinks are not connected to the same SAN fabric, then the
fabric becomes degraded and a log message indicates that the uplinks are connected to different SAN
switches. The WWN of the principal fabric switch indicates connectivity to the same SAN fabric in Virtual
Connect.
The VC-FC module uses dynamic login distribution to provide the following:
• Load balancing as new server HBA logins are completed through the uplink port with the least amount
of active logins
• A failover path if an uplink becomes unusable
Managing fabrics
Use the following screens to manage fabric settings:
• Define SAN Fabric screen (on page 111 )
o Define a SAN fabric, including selecting login re-distribution for SAN fabrics using HP VC
FlexFabric 10Gb/24-port Modules
• SAN Fabrics (External Connections) screen (on page 117 )
o View of list of SAN fabrics with external connection information
o Add, edit, or delete a fabric
o Redistribute logins on a SAN fabric
• SAN Fabrics (Server Connections) screen (on page 118 )
o View a list of SAN fabrics with server connection information
o Delete a fabric
o Redistribute logins on a SAN fabric
o Define a SAN fabric
• Edit SAN Fabric screen (on page 115 )
o Modify a fabric name
o Set the uplink port speed
o Change the login re-distribution
o Add or delete an uplink port
• Fibre Channel Settings (Misc.) screen (on page 120 )
o Set the time interval to wait after a link becomes unstable before automatic redistribution occurs
within the fabric
Define SAN Fabric screen
To define a SAN fabric, select the Define SAN Fabric link on the home page, click Define SAN Fabric on the
SAN Fabrics (Server Connections) ("
SAN Fabrics (Server Connections) screen " on page 118 ) screen, or
select SAN Fabric from the Define pull-down menu.
Only connect HP VC 4Gb FC module, HP VC 8Gb 24-Port FC module, HP VC 8Gb 20-Port FC module, or
FlexFabric FC uplinks to Fibre Channel switch ports that are NPIV-enabled.
