Fibre Channel With Vtl - HP StoreOnce 2700 Installation And Configuration Manual

NOTE: On Linux systems, it is possible that a client HBA port can open multiple concurrent
StoreOnce Catalyst over Fibre Channel connections to a target StoreOnce Fibre Channel port and
therefore it is sufficient to have a device count of 1. On Windows and HP-UX, this is not possible.
The number of devices per initiator port should be increased when multiple backup streams are
required so that multiple LUNs are presented to the client.
The number of paths available to a particular client is calculated as:
number of client ports
devices per initiator port

Fibre Channel with VTL

There are three StoreOnce GUI screens that relate to FC with VTL.
If required, the administrator may configure the port speed or topology from the VTL-Fibre
Channel Settings tab. The default settings are recommended.
NOTE:
in the StoreOnce Catalyst section of the GUI, if you are backing up to StoreOnce Catalyst
target devices over Fibre Channel. Port Speed or Topology settings, defined on either page,
apply to all target devices being backed up over Fibre Channel. Therefore, any changes here
will also apply to StoreOnce Catalyst target devices over Fibre Channel and vice versa.
When the user creates a library, using the VTL-Libraries-Create function, they specify which
FC ports it will use.
The world wide names for the ports can then be found on the VTL-Libraries-Interface Information
tab.
