Relaxing subnet restrictions
Beginning with Fabric OS 7.0.0x, subnet restrictions have been lifted. On HP DC SAN Director
Multiprotocol Extension Blade and HP 1606 SAN Extension Switch running pre-Fabric OS 7.0.0a,
there was restriction where each IPv4 Gigabit Ethernet interface must have had IP addresses on a
separate subnet from all other interfaces and IPv6 addresses must be on separate prefixes from all
other interfaces. In addition, the IPv6 interfaces must have had a unique link-local address from
the peer node on that interface.
GigE/xGigE port sharing across Logical Switches
On HP DC SAN Director Multiprotocol Extension Blade running pre-Fabric OS 7.0.0a, to create
a tunnel in a Logical Switch (LS), both the VE_Port and the corresponding GE_Port must be in the
same LS. Starting with Fabric OS 7.0.0a, this limitation is removed. That is, VE ports in different
LSs are able to share a GE_Port/xGE_Port that is present in the Default Switch.
Increase in number of circuits on 1 GE ports
In Fabric OS 7.0.0x, the number of circuits supported per tunnel on 1 GE ports has been increased
as follows:
• Up to 6 circuits per tunnel on HP 1606 SAN Extension Switch
• Up to 10 circuits per tunnel on HP DC SAN Director Multiprotocol Extension Blade
Encryption Platform Enhancements (HP StorageWorks Encryption SAN Switch / HP
StorageWorks DC Switch Encryption FC Blade)
Fabric OS 7.0.0x includes support for the key vault diagnostics. The key vault connectivity
information is periodically collected and any connectivity errors are reported as RASlog.
Access Gateway Enhancements
Detection of Unreliable N_Port Links
This feature monitors the reliability of a link on every N_Port of an Access Gateway. If the number
of ONLINE/OFFLINE SCNs (State Change Notifications) for a port exceeds a certain threshold
within a predefined time period, the link is considered unreliable and failback is disabled for that
port. Once the port is reliable again, user configured failback settings are enforced. The port
becomes reliable when the number of SCNs is less than the threshold value in the most recent time
interval.
RADIUS/LDAP support
Starting with Fabric OS 7.0.0x, RADIUS/Active Directory for user management is supported on
the switches operating in AG mode.
APM (Advanced Performance Monitoring) End to End and Frame Monitoring capability
Select Advanced Performance Monitoring capabilities in AG mode are features introduced in the
Fabric OS 7.0.0x release. Two types of performance monitors are supported in AG mode:
End-to-End Monitor and Frame Monitor.
F_Port Static Mapping
This feature allows users to change an existing F to N_Port mapping by executing a single CLI.
Here, F_Ports are statically mapped to an N_Port and port properties such as
failover/failback/preferred are always disabled. This new static mapping capability is in addition
to previously supported F to N_Port mappings where a user must execute multiple CLI commands
to map an F_Port to an N_Port.
