It is strongly recommended that the path between
the primary and secondary storage systems have a
minimum data transfer speed of 100 Mbps. If the
data transfer speed falls to 10 Mbps or lower, UR
operations cannot be properly processed. As a result,
many retries occur and UR pairs might be
suspended. This SOM is provided to ensure proper
system operation for data transfer speeds of at least
10 Mbps.
Mode 466 = ON: Data transfer speeds of 10 Mbps
and higher are supported. The JNL read is performed
with 4-multiplexed read size of 256 KB.
Mode 466 = OFF (default): For conventional
operations. Data transfer speeds of 100 Mbps and
higher are supported. The JNL read is performed
with 32-multiplexed read size of 1 MB by default.
Note: The data transfer speed can be changed using
the Change JNL Group options.
