Table 86 Enforcing hardware zoning, Fabric type, Methodology, Best practice

Page 388 highlights

• Is available on 1, 2, 4, 8 and 10 Gbps platforms. • Ensures that the name server does not return any information to an unauthorized initiator in response to a name server query. • Is exclusively enforced through selective information presented to end nodes through the fabric Simple Name Server (SNS). When an initiator queries the name server for accessible devices in the fabric, the name server returns only those devices that are in the same zone as the initiator. Devices that are not part of the zone are not returned as accessible devices. Fabric OS uses hardware-enforced zoning (on a per-zone basis) whenever the fabric membership or zone configuration changes. The exact zoning methodology varies on different switch models. Table 86 shows various HP switch models, the hardware zoning methodology for each, and tips for best usage. Table 86 Enforcing hardware zoning Fabric type Methodology Best practice Brocade 2000-series Enable hardware-enforced zoning only on domain,port zones; WWN or mixed zones are not hardware-enforced. Any domain,port zone that overlaps a mixed or WWN zone is not hardware-enforced. Use domain,port identifiers. Do not identify a zone member by its WWN. An overlap occurs when a member specified by WWN is connected to a port in a domain,port zone. The domain,port zone loses its hardware enforcement even though a review of the zone configuration does not indicate it. HP StorageWorks 4/8 SAN Switch, 4/16 SAN Switch, Brocade 4Gb SAN Switch for HP p-Class BladeSystem, Brocade 4Gb SAN Switch for HP c-Class BladeSystem, SAN Switch 4/32, 4/64 SAN Switch, SAN Switch 4/32B, 400 MP Router, 4/256 SAN Director, and the DC SAN Backbone Director (short name, DC Director) Enable hardware-enforced zoning on domain,port zones, and WWN zones. Overlap of similar zone types does not result in the loss of hardware enforcement. Overlap with other zone type results in the loss of hardware enforcement. As in the Brocade 2000-series switches, connecting a device specified by WWN to a port specified in a domain,port zone results in loss of the hardware enforcement in both zones. For the 4/256 SAN Director with an FC4-48 port blade and the DC Director with an FC8-48 port blade: If ports 16 through 47 on the FC4-48 port blade use domain,port identifiers, then session-based zoning is enforced on these ports. Use either WWN or domain,port identifiers. Mixed switches Enable hardware-enforced zoning according to each switch type. Use the portZoneShow command to find the zone type to which a device is attached. Use domain,port identifiers. You can use WWN identifiers if you place disk and tape targets on HP 2Gb and SAN Director 2/128 models, and do not use domain,port identifiers. 392 Administering Advanced Zoning

Administering Advanced Zoning
Is available on 1, 2, 4, 8 and 10 Gbps platforms.
Ensures that the name server does not return any information to an unauthorized initiator in response to
a name server query.
Is exclusively enforced through selective information presented to end nodes through the fabric Simple
Name Server (SNS). When an initiator queries the name server for accessible devices in the fabric, the
name server returns only those devices that are in the same zone as the initiator. Devices that are not
part of the zone are not returned as accessible devices.
Fabric OS uses hardware-enforced zoning (on a per-zone basis) whenever the fabric membership or zone
configuration changes.
The exact zoning methodology varies on different switch models.
Table 86
shows various HP switch
models, the hardware zoning methodology for each, and tips for best usage.

Best practice
Brocade
2000-series
Enable hardware-enforced zoning only on
domain,port
zones; WWN or mixed zones are
not hardware-enforced. Any
domain,port
zone
that overlaps a mixed or WWN zone is not
hardware-enforced.
An overlap occurs when a member specified
by WWN is connected to a port in a
domain,port
zone. The
domain,port
zone loses
its hardware enforcement even though a
review of the zone configuration does not
indicate it.
Use
domain,port
identifiers.
Do not identify a zone
member by its WWN.

Enable hardware-enforced zoning on
domain,port
zones, and WWN zones.
Overlap of similar zone types does not result in
the loss of hardware enforcement. Overlap
with other zone type results in the loss of
hardware enforcement.
As in the Brocade 2000-series switches,
connecting a device specified by WWN to a
port specified in a
domain,port
zone results in
loss of the hardware enforcement in both
zones.
For the 4/256 SAN Director with an
FC4-48 port blade and the DC Director
with an FC8-48 port blade:
If ports 16
through 47 on the FC4-48 port blade use
domain,port
identifiers, then session-based
zoning is enforced on these ports.
Use either WWN or
domain,port
identifiers.
Mixed switches
Enable hardware-enforced zoning according
to each switch type. Use the
portZoneShow
command to find the zone type to which a
device is attached.
Use
domain,port
identifiers.
You can use WWN
identifiers if you place disk
and tape targets on HP
2Gb and
SAN Director
2/128
models, and do not
use
domain,port
identifiers.
