network setup, and appliance configuration. The design of zACI allows a simpler product
(function) deployment model.
Several exploiters are planned for delivery through zACI. For instance, z/VSE Network
Appliance provides network access for TCP/IP socket applications running on z/VSE in an
LPAR. The z/VSE Network Appliance is an example of a product that is intended to be
managed by using the zACI infrastructure. IBM zAware is also designed to be implemented
by using the zACI partition, which replaces the zAware partition infrastructure used
previously. For more information about zACI, see Appendix A, "IBM z Appliance Container
Infrastructure" on page 449.
IBM z/VSE Network Appliance
The z/VSE Network Appliance builds on the z/VSE Linux Fast Path (LFP) function and
provides TCP/IP network access without requiring a TCP/IP stack in z/VSE. The appliance
uses zACI, which was introduced on z13 and z13s servers. Compared to a TCP/IP stack in
z/VSE, this configuration can support higher TCP/IP traffic throughput while reducing the
processing resource consumption in z/VSE. The z/VSE Network Appliance is an extension of
the IBM z/VSE - z/VM IP Assist (VIA®) function introduced on z114 and z196 servers. VIA
provides network access for TCP/IP socket applications running on z/VSE as a z/VM guest.
With the new z/VSE Network Appliance, this configuration is available for z/VSE systems
running in an LPAR. When available, the z/VSE Network Appliance is provided as a
downloadable package. It can then be deployed with the appliance installer.
In summary, the VIA function is available for z/VSE systems running as z/VM guests. The
z/VSE Network Appliance is available for z/VSE systems running without z/VM in LPARs.
Both provide network access for TCP/IP socket applications that use the Linux Fast Path.
However, no TCP/IP stack is required on the z/VSE system, and no Linux on z Systems
needs to be installed.
IBM zAware
IBM zAware is a feature that was introduced with the zEC12 that provides the next generation
of system monitoring. IBM zAware is designed to offer a near real-time, continuous-learning
diagnostic and monitoring capability. This function helps pinpoint and resolve potential
problems quickly enough to minimize their effects on your business.
The ability to tolerate service disruptions is diminishing. In a continuously available
environment, any disruption can have grave consequences. This negative effect is especially
true when the disruption lasts days or even hours. But increased system complexity makes it
more probable that errors occur, and those errors are also increasingly complex. Some
incidents' early symptoms go undetected for long periods of time and can become large
problems. Systems often experience "soft failures" (sick but not dead), which are much more
difficult and unusual to detect. IBM zAware is designed to help in those circumstances. For
more information, see Appendix B, "IBM z Systems Advanced Workload Analysis Reporter
(IBM zAware)" on page 453.
IBM zAware also now offers support for Linux running on z Systems and supports Linux
message log analysis. IBM zAware enables processing of message streams including those
without message IDs. It provides increased flexibility for analysis with the ability to group
multiple systems for modeling and analysis purposes together, which is especially helpful for
Linux workloads.
For use across the sysplex, IBM zAware now features an aggregated Sysplex view for z/OS
and system views. Visualization and usability are enhanced with an enhanced Heat Map
display, enhanced filtering and visualization capabilities, and improvements in time zone
display.
