1.6 ICSNET Pseudo Driver Performance Optimization
This kit provides an enhancement to the ICSNET pseudo driver that improves the
performance of the ics0 interface in a LAN cluster.
This optimization is helpful for cluster applications that use the ics0 interface to
interact with other nodes in the cluster. It does this by avoiding the latency associated
with time critical Interconnect Communication Subsystem (ICS) remote procedure
calls, and by using available bandwidth of the LAN interconnect directly, which
provides increased throughput.
This new functionality is enabled or disabled by the new sysconfigtab attribute,
described as follows:
icsnet:
icsnet_optimization_enable = 1
The following restrictions and limitations apply to the use of this feature:
1. This enhancement requires the version switch. Run the
/var/adm/patch/noroll/noroll_versw command, after the no-roll
installation.
2. There will not be any change in the statistics of the ics0 interface. All statistics
must be checked at the physical cluster interconnect level only.
3. Tcpdump behavior will change. The sender side behavior remains the same.
However, the receiving part of tcpdump must be checked at the physical interface
(cluster interconnect) level.
4. The ics0 interface MTU (Magnetic Tape Unit) will be dependent on the MTU of
the physical cluster interconnect. Any change in the MTU of the physical cluster
