Full Fabric
Remote Fabric
When a director or fabric switch (without the full volatility feature
installed) powers off or fails, a dump file is written to non-volatile
random-access memory (NV-RAM). This dump file retains the last 30
Fibre Channel frames transmitted from the embedded port and the
last four frames transmitted to the embedded port.
These Fibre Channel frames are then written to diskette and included
as part of the data collection procedure. This process constitutes a
security breach if the frame data includes classified information.
With the full volatility feature installed and enabled, no frame data is
stored and the NV-RAM dump does not occur when the director or
switch powers off or fails. Although this feature limits the diagnostic
information available for fault isolation and resolution, the majority
of failures are resolved without the dump file.
The Sphereon 4300 Fabric Switch is delivered without E_Port (ISL)
functionality and with all ports set to a BB_Credit value of 5. With the
full fabric feature installed and enabled, switch E_Port functionality
is provided and all port BB_Credit values are increased to 12. This
feature is provided only for the Sphereon 4300 Fabric Switch.
Intrepid 10000 Director LIMs contain two scalable packet processors,
each supporting an optical paddle pair. Each paddle pair provides 16
ports (1.0625 or 2.12500 Gbps operation), four ports (10.2000 Gbps
operation), or ten ports (mixed data rate operation). A minimal
BB_Credit buffer pool is allocated among all paddle-pair ports that
allows a 1.0625 or 2.12500 Gbps port to be set to 60 BB_Credits and a
10.2000 Gbps port to be set to 360 BB_Credits.
With the remote fabric feature installed and enabled, the buffer pool
is increased and each paddle pair is allocated a maximum of 1,373
BB_Credits. Feature enablement allows a long-link 1.0625 or 2.12500
Gbps port to be set to 1133 BB_Credits and a long-link 10.2000 Gbps
port to be set to 1085 BB_Credits. This feature is provided only for the
Intrepid 10000 Director.
