If you have gone for the zLinux virtual server option as
an alternative to multiple external servers then its
my guess you will want to maximise the advantage by
utilising the superfast speeds of the mainframe.
Putting in Hipersockets gives you high speed network
connections between all your virtual Linux servers and
LPARs running z/OS or S/390, that looks and feels just
like TCP/IP. Of course it is not TCP/IP - the connections
move data around from one memory location to another,
there is no physical cabling involved. IBM quotes the
following improvements in speeds "Benchmarks using two
LPARs each with four CPUs, each running 31-bit Linux
kernal 2.4.7 on a zSeries 900 HiperSockets demonstrated
up to four to six times more throughput than a single
Gigabit Ethernet for batch streaming traffic,and up
to between two and five times more throughput for interactive
traffic. This can translate into shorter batch windows
and faster response times".
