Firmware Summary
Expansion port (E_Port)
staging
E_Port staging not supported. The Intrepid 10000 Director
supports E_Port staging. The
director allows only one E_Port
connection to a neighbor switch
to take part in a fabric build
process. Upon process
completion, subsequent E_Ports
to neighbor switches are brought
up (staged). In addition, staged
E_Ports are brought up in
groups to minimize Class F
traffic and avoid overloading.
E_Port staging not supported.
ESS payload
processing and domain
port number zoning
E/OSc Version 6.0 (or earlier)
handshakes the ESS sequence
but does not apply content of
ESS payload to calculate port
numbering (PN) to logical port
address (PA) mapping. Legacy
directors and switches are
assumed to use an offset of four
for PN to PA mapping.
The Intrepid 10000 Director
sends and accepts payloads
specifying minimum and
maximum logical port addresses
and processes payload content
to calculate PN to PA mapping.
A correct mapping scheme
interprets domain port number
zoning enforcement across the
fabric and allows the director to
participate in a legacy fabric with
domain port number zoning.
E/OSi handshakes the ESS
sequence. However, domain port
number zoning not supported.
Registered state
change notification
(RSCN) coalescing
Only fabric login (FLOGI) and
Name Server events are
coalesced.
The Intrepid 10000 Director
coalesces all events that trigger
and transmit RSCNs to N_Ports.
This minimizes the number of
RSCNs generated.
SAN routers coalesce all RSCN
events.
Generating fabric
format RSCNs after
CTP failover (directors)
Does not replicate RSCN event
triggers, therefore transmits a
fabric format RSCN to all
attached devices after CTP card
failover.
Replicates events that trigger
RSCNs to the backup CTP,
therefore does not generate a
fabric format RSCN after CTP
failover.
RSCNs after CTP failover not
supported.
Hop count restriction Hop count of up to three is
supported. Devices more than
three hops away cannot be
reached.
No hop count restriction is
applied.
No hop count restriction is
applied.
Exchange switch
capabilities (ESC)
support
SW_ILS ESC sequence not
supported.
The Intrepid 10000 Director
processes SW_ILS ESC
sequences to identify
neighboring director ports.
SW_ILS ESC sequence not
supported.
