Zoning may not be necessary for small or simple configurations. Typically the bigger the SAN
is, the more zoning is needed. HPE recommends the following for determining how and when
to use zoning.
•
Small fabric (16 ports or less)—may not need zoning.
•
Small to medium fabric (16 - 128 ports)—use host-centric zoning. Host-centric zoning is
implemented by creating a specific zone for each server or host, and adding only those
storage elements to be used by that host. Host-centric zoning prevents a server from detecting
any other devices on the SAN or including other servers, and it simplifies the device discovery
process.
•
Disk and tape on the same pair of HBAs is supported along with the coexistence of array
multipath software (no multipath to tape or library devices on the StoreOnce System, but
coexistence of the multipath software and tape devices).
•
Large fabric (128 ports or more)—use host-centric zoning and split disk and tape targets.
Splitting disk and tape targets into separate zones prevents the StoreOnce System from
discovering unnecessary disk controllers. For optimal performance, where practical, dedicate
HBAs for disk and tape.
NOTE:
Overlapping zones are supported.
NOTE:
The HP Brocade SAN Switches support NPIV natively but the Cisco SAN Switches
require that it be turned on for each port used.
Configuring Fibre Channel
This section provides an overview only; see the
StoreOnce System User Guide
for detailed
instructions with screenshot examples.
For use with StoreOnce Catalyst stores
The
StoreOnce Catalyst — Fibre Channel Settings
tab is the main page for configuring
StoreOnce Catalyst over Fibre Channel.
•
In the
Devices
section, locate the
World Wide Node Name
and
World Wide Port Name
information for each port on the StoreOnce System. This is the information that you need
to zone the client with the StoreOnce System.
•
Also look at the
Identifier Name
in the top section of the screen. This is the FC address of
the StoreOnce System and is used to identify the StoreOnce System in the backup
application. It is in the format
CoFC-<device-id>
; if preferred, you may provide an
Identifier
Alias
, which will be easier to identify from the backup application.
•
The
Target Ports
section in the center of the screen is identical to the settings that you can
configure for VTL target devices over FC. The default values are recommended, but you
may edit
Speed
and
Topology
