I would like to add one other advantage that I took advantage of. When you define your hipersocket network, you can define a very large MTU size for the hipersocket network. This can eliminate a lot of segmentation/re-assembly overhead because the data transmission is broken up into fewer

In addition to the previous comments, there are some potential advantages to HiperSockets when considering workload portability. You may be able to ignore some OSA-Express physical and logical configuration considerations for inter-LPAR communications on, for example, a DR machine. That could

Remember SMC-D is only supported on z13 or z13s at Driver level 27 with z/OS 2.2. With these levels of H/W and OS, when comparing CPU utilization, SMC-D could be a better option than HiperSockets. The other point to note about OSes when comparing SMC-D with HiperSockets, SMC-D is only

Z/OS 2.2 also provides SMC-D, which I am eager to get a chance to play with. All the convenience and familiarity of sockets, but with most of the TCP/IP overhead stripped out (since the underlying transport layer is reliable). It should have significantly better performance and less CPU

Hipersockets are *MUCH MUCH* faster than exiting one LPAR and returning to another via OSA cards. This is done via an internal memory to memory transfer. All of the OSA overhead as well as the network latency are eliminated. However, as all LPAR's are in the same SYSPLEX, all of the data should

The real purpose of Hipersockets is fast LAN (TCP/IP) communication between LPARs inside single CPC. With no real add-on hardware like OSA card. With no chance for intruders. With the best performance possible. It cannot replace CTC. However many CTC exploiters can use TCP/IP links instead of
